schema.extension_parser.exsd Maven / Gradle / Ivy
This extension point is used to define the resource factory that handles a specific file (or URI) extension. The global EMF resource factory registry, <samp>Resource.Factory.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 file extension (without the leading .) that identifies the filenames and URIs to be handled by a resource factory.
A fully qualified name of the Java class implementing <samp>org.eclipse.emf.ecore.resource.Resource.Factory
</samp>.
1.0.0
Following is an example of how a URI extension can be registered:
<pre>
<extension point="org.eclipse.emf.ecore.extension_parser">
<parser type="xsd" class="org.eclipse.xsd.util.XSDResourceFactoryImpl"/>
</extension>
</pre>
The value of the class attribute must represent a class
that implements <samp>org.eclipse.emf.ecore.resource.Resource.Factory</samp>.
<p>
A URI extension can be also registered from the source code with the <samp>Resource.Factory.Registry.INSTANCE</samp> as follows:
</p>
<pre>
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("library", new XMIResourceFactoryImpl());
</pre>
The <samp>org.eclipse.emf.ecore.xmi</samp> plug-in extends this extension point to make the default EMF registrations: "ecore" is handled by <samp>EcoreResourceFactoryImpl</samp>, "emof" by <samp>EMOFResourceFactoryImpl</samp>, and <samp>XMIResourceFactoryImpl</samp> is the default.
