Metrics how integration with prometheus in 1.0.0-m1
Metrics had supported from Java chassis version 0.5.0,in version 1.0.0-m1,we had reconstruction it and add some more features,please checkout the user guide and release note for more information.Also subscribe ServiceComb<EMAIL_ADDRESS>and join discussion is welcome.
Background
Prometheus is a opensource open-source monitoring solution like Google Borgmon,also member of CNCF,community is very active.Java chassis metrics support integration with prometheus in 1.0.0-m1,and can use Grafana to query metrics data further.
Integration Principles
We known Java chassis developed by Java,so we use Simple Client in prometheus java client as SDK,the version we use is 0.1.0.
Prometheus use pull mode collect metrics data,microservice act as producer,we use Simple HTTP Server(also in client java SDK) publish them;
As an integration(optional) module,the implementation code is in metrics-integration/metrics-prometheus,you can get it’s dependency:
<dependency>
<groupId>io.prometheus</groupId>
<artifactId>simpleclient</artifactId>
</dependency>
<dependency>
<groupId>io.prometheus</groupId>
<artifactId>simpleclient_httpserver</artifactId>
</dependency>
<dependency>
<groupId>org.apache.servicecomb</groupId>
<artifactId>metrics-core</artifactId>
</dependency>
So if we import metrics-prometheus,no longer need to add metrics-core dependence.
How Configuration
Enable prometheus integration is very easy:
Global Configuration
Please add prometheus port config in microservice.yaml:
APPLICATION_ID: demo
service_description:
name: demoService
version: 0.0.1
servicecomb:
metrics:
prometheus:
#prometheus provider port
port: 9696
If do not config,default value is 9696
Maven Configuration
We just only need add metrics-prometheus dependency:
<dependency>
<groupId>org.apache.servicecomb</groupId>
<artifactId>metrics-prometheus</artifactId>
<version>1.0.0-m1</version>
</dependency>
Config prometheus.yml in Prometheus
You need add job in prometheus.yml,like:
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ['localhost:9090']
- job_name: 'servicecomb'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ['localhost:9696']
The job_name: ‘servicecomb’ is our custom job,it will collect metrics data from local microservice localhost:9696,more information about configuration of prometheus can found here.
Verify Output
Prometheus Simple HTTP Server use /metrics as default URL,metrics-prometheus will use 9696 as default port,after microservice start up you can get metrics data at http://localhost:9696/metrics.
Prometheus Simple HTTP Server provider interface will publish the standard format which prometheus needed:

LIFE IS BEAUTIFUL (1997) A Film Review by Ted Prigge Copyright 1998 Ted Prigge
Director: Roberto Benigni Writers: Vincenzo Cerami and Roberto Benigni Starring: Roberto Benigni, Nicoletta Braschi, Giorgio Cantarini, Giustino Durano, Sergio Bini Bustric, Marisa Peredes, Horst Bucholz, Lidia Alfonsi
The entire world has been praising Roberto Benigni's "Life is Beautiful," and I'm no exception to that. I too think it's a wonderful flick, but I suspect for different reasons. Everyone's been praising this as a great uplifter, a - oh, how did they put it? - "triumph of the human spirit." In fact, the opposite is true, and it took me awhile to come to my conclusion that the entire film is about man's ability for denial, and the way horrific instances cause certain people to pervert reality in favor of themselves, and thus harm others considerably, if not mortally, psychologically. I can remember seeing it vividly: I laughed through the first, magical half, then hardly peeped during the second, except to let out a couple hollow laughs at some rather funny moments.
But as I went home, I felt unsatisfied in my delight for the film, while my movie-going companion seemed to think it was the greatest film of the year, without a shred of doubt. Cute, witty, and sad. Sure, it was.  But the more I thought of it, I decided that my primary reasoning had, in fact, been compeltely off.
Let me lay out the film for you, first, to illustrate my point. The film, as you may have heard, is about the Holocaust, but it's also a comedy (don't mesh those words together, though: this is not a "holocaust comedy," as I describe it to some of my friends who haven't seen it, jokingly). Great Italian comic actor Roberto Benigni directs, co-writes, and stars in the film as a hapless character who is a joyous motormouth, a wonderfully adept physical comedian, and also energetic and charismatic. He's not exactly the Little Tramp or Buster Keaton or anyone else from the silent era though: he's an original creation, though a bit inspired by them.
But anyway, his character, Guido, moves to a lovely, picturesque Italian city in the beginning of the film, and along the way, meets and falls in love with a beautiful woman, Dora (Nicoletta Braschi, his wife and thus his co-star).  Much of the first fifty minutes deals with his attempts to woo her, by bending reality so that he can be with her, and his attempts at becoming a respectable waiter so that he can make money and one day open a bookstore of his own.
It's all rather predictable, and we've seen it all before, but that hardly means it's arbitrary to the rest of the film; the first half is hilarious and witty and charming and it's completely entertaining in the way films today aren't. Gags abound, and the romance between Guido and Dora becomes sweet like romances aren't these days. However, this first half isn't just cuteness: it's deceptively complex, with hints that this film may be deeper than just uplifting, and that Benigni probably just didn't stumble onto something more interesting. As Benigni courts Dora, he finds he is able to bend reality, and soon keys are popping into his hand at will, and she's becoming truly in love with him because he is so magical and wonderful and so not the bore her temper-ridden fiance is. By the time, he rides into her engagement reception on a horse and sweeps her off her feet, the film has almost transcended any traces of realism, and become a truly magical experience...and take note of that, because they carry on a picturesque, near-perfect life together. They have a child named Giousť (Giorgio Cantarini), he opens the bookstore, and they stay completely in love with eachother. They also live in Italy during the holocaust and Guido just happens to be Jewish, so when he and Giousť are taken away by Nazis to go to concentration camp, their life is shattered.
Now here's where the film becomes complicated, not to mention controversial: in order to protect his son from the horrors, Guido lies to Giousť and tells him that it's all a game, an adventure holiday disguised as a horrific prison. Points are handed out for doing things like not asking for desert, and hiding from the Nazis, and not screaming. In fact, in one scene when a German officer comes into the shack where the prisoners are held and asks for an interpretor, a non-German-speaking Guido says he can translate and turns every word and every gesture the officer makes into a description of the rules of the game. The complicated thing about this is is he really protecting Giousť? By the end (if you don't want to hear what happens, skip a paragraph or three), when Guido has been gunned down by an officer for making trouble, and Giousť thinks he has won the game by collecting a thousand points, and is then reunited with his mother in one beautifully uplifting reunion where they're both happy to see eachother and have no clue their father and husband is lying in a ditch a couple miles away, you have to wonder if this isn't the least uplifting film of the year disguised as the exact opposite. Though the narration by an older Giousť says he's happy his father retained his son's humanity, it's a wonder if everyone in this film isn't in deep denial, and if they are, this has to be the entire point of the film. Guido, a man who has been able to pervert the truth for the entire film, finds himself in real hellish conditions, and tries to fix them by lying to himself and to his son, finally meets a tragic conclusion - not so uplifting anymore, eh?
But that's what's so extremely interesting about this film. It's deceptive and clever, and it certainly had me thinking it was something else and not such a downbeat film. In fact, this may be the greatest hoax in contemporary cinema: the film has been praised as the great humane film of the year, been awarded numerous accolades from organizations who usually don't recognize films, and Benigni himself has gone around discussing how it is a great message for his life, and how his father used to water down the stories of his life in a concentration camp to not freak his kids out. Maybe a little bit older, Benigni has recognized the errors of his father's ways: by not telling the truth, he has perhaps awakened some deep psyhological demons in his son when he learned the bitter truth about life, and Benigni, clever bastard that he is, has constructed a film so complex that it can only be accurately discerned by heavy thinking and a lack of suppression. The fact that I denied the final shot, the key to the entire film's truth, and thought it was a great uplifter was one example of Benigni's genius as a filmmaker.
In fact, out of all the reviews I've read for this film, only one other critic in the entire world agrees with me, and that's Mike D'Angelo, who makes the exact same case as I do, and likes it about as much as I do. He too spotted the hints, the allusions to Schopenhauer, and the little tricks Benigni uses to make his point about denial so incredibly truthful, that if the only thing I have wrong with this film is that it is deceptive. I'm always a tad taken back at a film that uses manipulation to make its own ends meet, and I'm a little appalled that Benigni has let it go as far as he has (unless, of course, I'm reading this film completely wrong, and that's not out of the question).
Add that along with the fact that the second half is just not as great as it should be, even with the deception, and you have a film which is, yes, great, but perhaps not as great as it could be. I admire the fact that it goes to such far lengths to get its point across. But that doesn't mean that it's perfect. But as it is, "Life is Beautiful" may be the most engagingly ironic film to ever hit the big screen - a film that I fear may result in bad word of mouth if every critic realized the truth behind the mask long after they've praised it for being so incredibly "uplifting."

This section covers the common abilities of STL container classes. Most of them are requirements that, in general, every STL container should meet. The three core abilities are as follows:
All containers provide value rather than reference semantics. Containers copy elements internally when they are inserted rather than managing references to it. Thus, each element of an STL container must be able to be copied. If objects you want to store don't have a public copy constructor, or copying is not useful (for example, because it takes time or elements must be part of multiple containers), the container elements must be pointers or pointer objects that refer to these objects. Section 5.10.2, covers this problem in detail.
In general, all elements have an order. Thus, you can iterate one or many times over all elements in the same order. Each container type provides operations that return iterators to iterate over the elements. This is the key interface of the STL algorithms.
In general, operations are not safe. The caller must ensure that the parameters of the operations meet the requirements. Violating these requirements (such as using an invalid index) results in undefined behavior. Usually the STL does not throw exceptions by itself. If user-defined operations called by the STL containers do throw, the behavior is different. See Section 5.11.2, for details.
The operations common to all containers meet the core abilities that were mentioned in the previous subsection. Table 6.1 lists these operations. The following subsections explore some of these common operations.
Every container class provides a default constructor, a copy constructor, and a destructor. You can also initialize a container with elements of a given range. This constructor is provided to initialize the container with elements of another container, with an array, or from standard input. These constructors are member templates (see page 11), so not only the container but also the type of the elements may differ, provided there is an automatic conversion from the source element type to the destination element type.[2] The following examples expand on this:
[2] If a system does not provide member templates, it will typically allow only the same types. In this case, you can use the copy() algorithm instead. See page 188 for an example.
| Operation | Effect |
|---|---|
| ContType c | Creates an empty container without any element |
| ContType c1(c2) | Copies a container of the same type |
| ContType c(beg,end) | Creates a container and initializes it with copies of all elements of [beg,end) |
| c.~ContType() | Deletes all elements and frees the memory |
| c.size() | Returns the actual number of elements |
| c.empty() | Returns whether the container is empty (equivalent to size()==0, but might be faster) |
| c.max_size() | Returns the maximum number of elements possible |
| c1 == 2 | Returns whether c1 is equal to c2 |
| c1 != c2 | Returns whether c1 is not equal to c2 (equivalent to !(c1==c2)) |
| c1 < c2 | Returns whether c1 is less than c2 |
| c1 > c2 | Returns whether c1 is greater than c2 (equivalent to c2<c1 |
| c1 <= c2 | Returns whether c1 is less than or equal to c2 (equivalent to !(c2<c1)) |
| c1 >= c2 | Returns whether c1is greater than or equal to c2 (equivalent to !(c1<c2)) |
| c1 = c2 | Assigns all elements of c1 to c2 |
| c1.swap(c2) | Swaps the data of c1and c2 |
| swap(c1,c2) | Same (as global function) |
| c.begin() | Returns an iterator for the first element |
| c.end() | Returns an iterator for the position after the last element |
| c.rbegin() | Returns a reverse iterator for the first element of a reverse iteration |
| c.rend() | Returns a reverse iterator for the position after the last element of a reverse iteration |
| c.insert(pos,elem) | Inserts a copy of elem (return value and the meaning of pos differ) |
| c.erase(beg,end) | Removes all elements of the range [beg,end) (some containers return next element not removed) |
| c.clar() | Removes all elements (makes the container empty) |
| c.get_allocator() | Returns the memory model of the container |
Initialize with the elements of another container:
std::list<int> l; //l is a linked list of ints ... //copy all elements of the list as floats into a vector std::vector<float> c(l.begin(),l.end());
Initialize with the elements of an array:
int array[] = { 2, 3, 17, 33, 45, 77 }; ... //copy all elements of the array into a set std::set<int> c(array,array+sizeof(array)/sizeof(array[0]));
Initialize by using standard input:
//read all integer elements of the deque from standard input std::deque<int> c((std::istream_iterator<int>(std::cin)), (std::istream_iterator<int>()));
Don't forget the extra parentheses around the initializer arguments here. Otherwise, this expression does something very different and you probably will get some strange warnings or errors in following statements. Consider writing the statement without extra parentheses:
std::deque<int> c(std::istream_iterator<int>(std::cin), std::istream_iterator<int>());
In this case, c declares a function with a return type that is deque<int>. Its first parameter is of type istream_iterator<int> with the name cin, and its second unnamed parameter is of type "function taking no arguments returning istream_iterator<int>." This construct is valid syntactically as either a declaration or an expression. So, according to language rules, it is treated as a declaration. The extra parentheses force the initializer not to match the syntax of a declaration.[3]
[3] Thanks to John H. Spicer from EDG for this explanation.
In principle, these techniques are also provided to assign or to insert elements from another range. However, for those operations the exact interfaces either differ due to additional arguments or are not provided for all container classes.
For all container classes, three size operations are provided:
size()
Returns the actual number of elements of the container.
empty()
Is a shortcut for checking whether the number of elements is zero (size()==0). However, empty() might be implemented more efficiently, so you should use it if possible.
max_size()
Returns the maximum number of elements a container might contain. This value is implementation defined. For example, a vector typically contains all elements in a single block of memory, so there might be relevant restrictions on PCs. Otherwise, max_size() is usually the maximum value of the type of the index.
The usual comparison operators ==, ! =, <, <=, >, and >= are defined according to the following three rules:
Both containers must have the same type.
Two containers are equal if their elements are equal and have the same order. To check equality of elements, use operator ==.
To check whether a container is less than another container, a lexicographical comparison is done(see page 360).
To compare containers with different types, you must use the comparing algorithms of Section 9.5.4.
If you assign containers, you copy all elements of the source container and remove all old elements in the destination container. Thus, assignment of containers is relatively expensive.
If the containers have the same type and the source is no longer used, there is an easy optimization: Use swap(). swap() offers much better efficiency because it swaps only the internal data of the containers. In fact, it swaps only some internal pointers that refer to the data (elements, allocator, sorting criterion, if any). So, swap() is guaranteed to have only constant complexity, instead of the linear complexity of an assignment.

JUST IN: Gunmen kidnap nursing mother, baby, others in Kaduna
by Godwin IsenyoGodwin Isenyo, Kaduna
Some gunmen suspected to be kidnappers have abducted six persons including a nursing mother with her three-week-old baby at Hayin Danmani Community in Igabi Local Government Area of Kaduna State.
It was gathered that the incident took place on Tuesday night but community residents got to know about it on Wednesday.
Our correspondent also gathered that the kidnappers may have returned to the community on Wednesday night.
A source said, “We heard gunshots yesterday (Wednesday) night and it is possible that they (kidnappers) revisited.”
Meanwhile, it was also gathered that the kidnappers contacted the family of one of the victims and demanded a ransom of N10 million.
A source, who spoke on the condition of anonymity, told our correspondent that when the gunmen invaded the community, they shot indiscriminately and went from house-to-house to pick their victims.
One of the community leaders said the residents of the community were not living in fear.
He said while the kidnappers picked the nursing mother and her three-week-old baby, her husband managed to escape.
He added that the kidnappers made away with six other people, who were mostly peasants.
He said, “The incident actually took place on Tuesday night but the community discovered the abduction yesterday (Wednesday) morning.
“We learnt that they made away with a nursing mother and her three-week-old baby.
“You know that Mahuta, Mando, Rigasa, Danmani communities share common boundaries with Dogon Daji which lead to Birnin Gwari, where a military operation is ongoing. It is possible that the military operation is becoming unbearable for the bandits. So, they are being pushed into the communities mentioned.”
As of the time of filing this report, the State Command of the Police had yet to confirm the incident as the spokesman of the command, DSP Yakubu Sabo didn’t respond to our correspondent’s telephone call.

JComboBox
, which lets the user choose one of several choices,
can have two very different forms.
The default form
is the uneditable combo box,
which features a button
and a drop-down list of values.
The second form, called the editable combo box,
features a text field
with a small button abutting it.
The user can type a value in the text field
or click the button to display a drop-down list.
Here's what the two forms of combo boxes look like
in the Java look and feel:
|
|
|
|
|
|
| Uneditable combo box, before (top)
and after the button is clicked | Editable combo box, before and after
the arrow button is clicked |
Combo boxes require little screen space, and their editable (text field) form is useful for letting the user quickly choose a value without limiting the user to the displayed values. Other components that can display one-of-many choices are groups of radio buttons and lists. Groups of radio buttons are generally the easiest for users to understand, but combo boxes can be more appropriate when space is limited or more than a few choices are available. Lists are not terribly attractive, but they're more appropriate than combo boxes when the number of items is large (say, over 20) or when selecting multiple items might be valid.
Because editable and uneditable combo boxes are so different, this section treats them separately. This section covers these topics:
ComboBoxDemo.java
vs.
RadioButtonDemo.java
.
ComboBoxDemo.java
,
creates an uneditable combo box
and sets it up:
String[] petStrings = { "Bird", "Cat", "Dog", "Rabbit", "Pig" }; //Create the combo box, select item at index 4. //Indices start at 0, so 4 specifies the pig. JComboBox petList = new JComboBox(petStrings); petList.setSelectedIndex(4); petList.addActionListener(this);
The preceding code registers an action listener on the combo box. To see the action listener implementation and learn about other types of listeners supported by combo box, refer to Handling Events on a Combo Box.
No matter which constructor you use,
a combo box uses a combo box model
to contain and manage the items in its menu.
When you initialize a combo box with an array or a vector,
the combo box creates a default model object for you.
As with other Swing components,
you can customize a combo box
in part by implementing a custom model —
an object that implements the
ComboBoxModel
interface.
JComboBox
methods that change
the items in the combo box's menu,
such as insertItemAt
,
work only if the data model implements the
MutableComboBoxModel
interface
(a subinterface of ComboBoxModel
).
Refer to the
API tables to see which methods are affected.
Something else to watch out for —
even for uneditable combo boxes —
is ensuring that your custom model fires
list data events when the combo box's data or state changes.
Even immutable combo box models,
whose data never changes,
must fire a list data event
(a CONTENTS_CHANGED
event)
when the selection changes.
One way to get the list data event firing code for free
is to make your combo box model a subclass of
AbstractListModel
.
ComboBoxDemo.java
that registers and implements an action listener on the combo box:
public class ComboBoxDemo ... implements ActionListener { . . . petList.addActionListener(this) { . . . public void actionPerformed(ActionEvent e) { JComboBox cb = (JComboBox)e.getSource(); String petName = (String)cb.getSelectedItem(); updateLabel(petName); } . . . }
Combo boxes also generate item events,
which are fired when any of the items' selection state changes.
Only one item at a time can be selected in
a combo box, so when the user makes a new selection
the previously selected item becomes unselected.
Thus two item events are fired each time the user
selects a different item from the menu.
If the user chooses the same item,
no item events are fired.
Use addItemListener
to register an item listener
on a combo box.
How to Write an Item Listener gives general information about implementing item listeners.
Although JComboBox
inherits methods
to register listeners for
low-level events —
focus, key, and mouse events, for example —
we recommend that
you don't listen for low-level events on a combo box.
Here's why:
A combo box is a compound component —
it is comprised of two or more other components.
The combo box itself fires high-level events such as action events.
Its subcomponents fire low-level events such as mouse,
key, and focus events.
The low-level events and the subcomponent that fires
them are look-and-feel-dependent.
To avoid writing look-and-feel-dependent code,
you should listen only for high-level events
on a compound component such as a combo box.
For information about events, including a discussion about
high- and low-level events, refer to
Writing Event Listeners.
Using an Editable Combo Box
Here's a picture of a demo application
that uses an editable combo box to enter a pattern
with which to format dates.
The following code, taken from
ComboBoxDemo2.java
,
creates and sets up the combo box:
String[] patternExamples = { "dd MMMMM yyyy", "dd.MM.yy", "MM/dd/yy", "yyyy.MM.dd G 'at' hh:mm:ss z", "EEE, MMM d, ''yy", "h:mm a", "H:mm:ss:SSS", "K:mm a,z", "yyyy.MMMMM.dd GGG hh:mm aaa" }; . . . JComboBox patternList = new JComboBox(patternExamples); patternList.setEditable(true); patternList.addActionListener(this);
An editable combo box fires an action event when the user chooses an item from the menu and when the user types Enter. Note that the menu remains unchanged when the user enters a value into the combo box. If you want, you can easily write an action listener that adds a new item to the combo box's menu each time the user types in a unique value.
See
Internationalization to learn more about formatting dates
and other types of data.
Providing a Custom Renderer
A combo box uses a renderer to display each item in its menu.
If the combo box is uneditable,
it also uses the renderer to display the currently selected item.
An editable combo box, on the other hand,
uses an editor to display the selected item.
A renderer for a combo box must implement the
ListCellRenderer
interface.
A combo box's editor must implement
ComboBoxEditor
.
This section shows how to provide
a custom renderer for an uneditable combo box.
The default renderer knows how to render strings and icons.
If you put other objects in a combo box,
the default renderer calls the toString
method to provide a string to display.
You can customize the way a combo box renders itself
and its items
by implementing your own ListCellRenderer
.
Here's a picture of an application that uses a combo box with a custom renderer:
Click the Launch button to run the CustomComboBox Demo using Java™ Web Start (download JDK 6). Alternatively, to compile and run the example yourself, consult the example index.
The full source code for this example is in
CustomComboBoxDemo.java
.
To get the image files it requires,
consult the
example index.
The following statements from the example
create an instance of ComboBoxRenderer
(a custom class)
and set up the instance as the combo box's renderer:
JComboBox petList = new JComboBox(intArray); . . . ComboBoxRenderer renderer = new ComboBoxRenderer(); renderer.setPreferredSize(new Dimension(200, 130)); petList.setRenderer(renderer); petList.setMaximumRowCount(3);
The last line sets the combo box's maximum row count,
which determines the number of items visible when
the menu is displayed.
If the number of items in the combo box is larger than
its maximum row count, the menu has a scroll bar.
The icons are pretty big for a menu,
so our code limits the number of rows to 3.
Here's the implementation of ComboBoxRenderer
,
a renderer that puts an icon and text side-by-side:
class ComboBoxRenderer extends JLabel implements ListCellRenderer { . . . public ComboBoxRenderer() { setOpaque(true); setHorizontalAlignment(CENTER); setVerticalAlignment(CENTER); } /* * This method finds the image and text corresponding * to the selected value and returns the label, set up * to display the text and image. */ public Component getListCellRendererComponent( JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { //Get the selected index. (The index param isn't //always valid, so just use the value.) int selectedIndex = ((Integer)value).intValue(); if (isSelected) { setBackground(list.getSelectionBackground()); setForeground(list.getSelectionForeground()); } else { setBackground(list.getBackground()); setForeground(list.getForeground()); } //Set the icon and text. If icon was null, say so. ImageIcon icon = images[selectedIndex]; String pet = petStrings[selectedIndex]; setIcon(icon); if (icon != null) { setText(pet); setFont(list.getFont()); } else { setUhOhText(pet + " (no image available)", list.getFont()); } return this; } . . . }
ListCellRenderer
,
ComboBoxRenderer
implements a method
called getListCellRendererComponent
,
which returns a component whose paintComponent
method is used to display the combo box and each of its items.
The easiest way to display an image and an icon
is to use a label.
So ComboBoxRenderer
is a subclass of label
and returns itself.
The implementation of getListCellRendererComponent
configures the renderer to display the currently selected
icon and its description.
These arguments are passed to getListCellRendererComponent
:
JList list
—
a list object used behind the scenes
to display the items.
The example uses this object's colors
to set up foreground and background colors.
Object value
—
the object to render.
An Integer
in this example.
int index
—
the index of the object to render.
boolean isSelected
—
indicates whether the
object to render is selected.
Used by the example to determine which colors to use.
boolean cellHasFocus
—
indicates whether the
object to render has the focus.
ListCellRenderer
.
You can save yourself some time
by sharing renderers between
combo boxes and lists,
if it makes sense for your program.
JComboBox
constructors and methods.
Other methods you are most likely to invoke on
a JComboBox
object are those
it inherits from its superclasses,
such as setPreferredSize
.
See
The JComponent API
for tables of commonly used inherited methods.
The API for using combo boxes falls into two categories:
| Method | Purpose |
|---|---|
|
JComboBox() JComboBox(ComboBoxModel) JComboBox(Object[]) JComboBox(Vector) |
Create a combo box with the specified items in its menu.
A combo box created with the default constructor has no
items in the menu initially.
Each of the other constructors initializes the menu
from its argument: a model object,
an array of objects, or a Vector of objects.
|
|
void addItem(Object) void insertItemAt(Object, int) |
Add or insert the specified object into the combo box's menu.
The insert method places the specified object at
the specified index, thus inserting it before the object currently
at that index.
These methods require that the combo box's data model
be an instance of MutableComboBoxModel .
|
|
Object getItemAt(int) Object getSelectedItem() |
Get an item from the combo box's menu. |
|
void removeAllItems() void removeItemAt(int) void removeItem(Object) |
Remove one or more items from the combo box's menu.
These methods require that the combo box's data model
be an instance of MutableComboBoxModel .
|
| int getItemCount() | Get the number of items in the combo box's menu. |
|
void setModel(ComboBoxModel) ComboBoxModel getModel() |
Set or get the data model that provides the items in the combo box's menu. |
|
void setAction(Action) Action getAction() |
Set or get the Action
associated with the combo box.
For further information, see
How to Use Actions.
|
| Method or Constructor | Purpose |
|---|---|
| void addActionListener(ActionListener) | Add an action listener to the combo box.
The listener's actionPerformed method is called
when the user selects an item from the combo box's menu
or, in an editable combo box, when the user presses Enter.
|
| void addItemListener(ItemListener) | Add an item listener to the combo box.
The listener's itemStateChanged method is called
when the selection state of any of the combo box's items change.
|
|
void setEditable(boolean) boolean isEditable() |
Set or get whether the user can type in the combo box. |
|
void setRenderer(ListCellRenderer) ListCellRenderer getRenderer() |
Set or get the object responsible for painting the selected item in the combo box. The renderer is used only when the combo box is uneditable. If the combo box is editable, the editor is used to paint the selected item instead. |
|
void setEditor(ComboBoxEditor) ComboBoxEditor getEditor() |
Set or get the object responsible for painting and editing the selected item in the combo box. The editor is used only when the combo box is editable. If the combo box is uneditable, the renderer is used to paint the selected item instead. |

Serves 3-4
Pot-roasting pheasant keeps it deliciously moist. Potato and sweetcorn mash makes the perfect accompaniment.
For the pot roast, place a flameproof casserole large enough to take the pheasants and all the carrots over a high heat. Add the butter and the oil and melt together.
Add the pheasant and fry, turning regularly, until golden-brown all over, then remove from the casserole and set aside.
Reduce the heat, then stir the onion and garlic into the fat and fry gently for 3-4 minutes, or until tender.
Add the carrots and tarragon and stir around for 4-5 minutes, then return the pheasant to the pot, nestling it breast-side down in among the carrots.
Pour over the Riesling and season, to taste, with salt and freshly ground black pepper.
Bring up to the boil, then cover with a tight-fitting lid. Turn the heat down low and leave to cook gently for one hour, turning the pheasants over after 30 minutes.
Meanwhile, for the mash, place the milk into a saucepan and bring to the boil. Remove from the heat, add the saffron and set aside to infuse.
Cut the baked potatoes in half and scoop the flesh out into a clean saucepan. Add the butter and salt, to taste, and place over a low heat.
Gradually add the saffron milk, mashing continuously. Stop and assess the texture - if you prefer your mash softer and runnier then add more milk.
Add the sweetcorn and season, to taste, with salt and freshly ground black pepper.
To finish the pot roast, check that the pheasant is tender and cooked through, then lift out onto a serving plate and keep warm.
Add the cream to the casserole and simmer for two minutes. Season, to taste, with salt and freshly ground black pepper.
Spoon the sauce around the pheasants and serve the mash alongside.

DESCRIPTION
The
getpwent()
function returns a pointer to a structure containing
the broken-out fields of a record from the password database
(e.g., the local password file
/etc/passwd,
NIS, and LDAP).
The first time
getpwent()
is called, it returns the first entry; thereafter, it returns successive
entries.
The
setpwent()
function rewinds to the beginning
of the password database.
The
endpwent()
function is used to close the password database
after all processing has been performed.
The passwd structure is defined in <pwd.h> as follows:
struct passwd {
char *pw_name; /* username */
char *pw_passwd; /* user password */
uid_t pw_uid; /* user ID */
gid_t pw_gid; /* group ID */
char *pw_gecos; /* user information */
char *pw_dir; /* home directory */
char *pw_shell; /* shell program */
};
For more information about the fields of this structure, see
passwd(5).
RETURN VALUE
The
getpwent()
function returns a pointer to a
passwd
structure, or NULL if
there are no more entries or an error occurred.
If an error occurs,
errno
is set appropriately.
If one wants to check
errno
after the call, it should be set to zero before the call.
The return value may point to a static area, and may be overwritten
by subsequent calls to
getpwent(),
getpwnam(3),
or
getpwuid(3).
(Do not pass the returned pointer to
free(3).)

Some time ago I developed a pretty simple SPA with Rails on backend & React.js on the front. It was pretty simple, but (surprisingly for me!) started to grow like on steroids. Rails started to be a bottleneck since one of the customer requirements was not just making application fast. He wanted it to be instant.
It’s not a big deal to buy a couple of servers. But 50 ms response isn’t enough for my client. So, I decided to rewrite backend on something else. After long thinking I chose elixir & phoenix.
I want to share this transition details with you - maybe you can find something interesting.
You have to run rails & phoenix on the same address to prevent battle with CORS.
I solved this by installing nginx
locally & configuring it to serve few servers on the same address. /etc/nginx/conf.d/development.conf
listing:
server {
listen 80;
server_name development.local;
location / {
proxy_pass http://<IP_ADDRESS>:3000; // rails server
}
location /api {
proxy_pass http://<IP_ADDRESS>:4000; // phoenix server; as you can notice, my rails server doesn't have even /api namespace - it was just a rapid prototype
}
}
restart nginx, add these lines to etc/hosts/
:
# For elixir-to-rails transition
<IP_ADDRESS> development.local
and you can open http://development.local
in your browser.
