PlantUML is a component that allows to quickly write diagrams from text.
This extension point is used to define a content handler that describes content types.
The global EMF content handler registry, <samp>ContentHandler.Registry.INSTANCE</samp>, is used to record the registration.
A fully qualified identifier of the target extension point.
An optional identifier of the extension instance.
An optional name of the extension instance.
A fully qualified name of the Java class implementing <samp>org.eclipse.emf.ecore.resource.Resource.Factory
</samp>.
2.4.0
Following is an example of how a URI content handler can be registered:
<pre>
<extension point="org.eclipse.emf.ecore.content_handler" >
<contentHandler
class="org.eclipse.emf.ecore.resource.impl.PlatformContentHandlerImpl"
priority="2000">
</contentHandler>
</extension>
</pre>
The value of the class attribute must represent a class
that implements <samp>org.eclipse.emf.ecore.resource.ContentHandler</samp>.
It must either have a no argument contructor
or if there are parameters in the body of the configuration element,
a constructor taking a <samp>Map<String, String></samp> argument representing those parameters.
<p>
A content handler can be also registered from the source code with the <samp>ContentHandler.Registry.INSTANCE</samp> as follows:
</p>
<pre>
ContentHandler.Registry.INSTANCE.getContentTypeToFactoryMap().put(2000, new PlatformContentHandlerImpl());
</pre>
