<p>This object can also be used to access the metadata related with the application like
<code class="docutils literal"><span class="pre">applicationId</span></code>, <code class="docutils literal"><span class="pre">taskId</span></code>,
and <code class="docutils literal"><span class="pre">stateDir</span></code>, and also record related metadata as <code class="docutils literal"><span class="pre">topic</span></code>,

<div class="highlight-java"><div class="highlight"><pre><span></span><span class="n">public void process(String key, String value) {</span>
- <span class="c1">// add a heaeder to the elements</span>
+ <span class="c1">// add a header to the elements</span>
<span class="n">context()</span><span class="o">.</span><span class="na">headers</span><span class="o">()</span><span class="o">.</span><span class="na">add</span><span class="o">.</span><span class="o">(</span><span class="s">&quot;key&quot;</span><span class="o">,</span> <span class="s">&quot;key&quot;</span>
