| 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> |
| </documentation> |
| </annotation> |
| |
| <annotation> |
| <appInfo> |
| <meta.section type="apiInfo"/> |
| </appInfo> |
| <documentation> |
| 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&lt;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> |
