 <h3 id="implement-the-interface-mediaentityprocessor">Implement the interface 
<code>MediaEntityProcessor</code><a class="headerlink" 
href="#implement-the-interface-mediaentityprocessor" title="Permanent 
link">&para;</a></h3>
 <p>As you can see the <a 
href="http://olingo.apache.org/javadoc/odata4/org/apache/olingo/server/api/processor/MediaEntityProcessor.html";><code>MediaEntityProcessor</code>(Javadoc)</a>
 extends <a 
href="http://olingo.apache.org/javadoc/odata4/org/apache/olingo/server/api/processor/EntityProcessor.html";><code>EntityProcessor</code></a>,
 therefore we will implement <code>MediaEntityProcessor</code> in class 
<code>DemoEntityProcessor</code>.</p>
 <p>The easiest part is to delete an media entity. The method 
<code>deleteMediaEntity</code> is delegated to the method 
<code>deleteEntity(...)</code>.</p>
