| * <p> |
| * Adds an entry to the extension to factory map of the {@link ResourceFactoryRegistryImpl resource factory registry} on |
| * the {@link TransactionalEditingDomain editing domain}'s underlying {@link ResourceSet resource set} making sure that |
| * the {@link ExtendedUMLResourceFactoryImpl extended UML2 resource factory} provided by Sphinx will be used to create |
| * {@link Resource resource}s for *.uml files. |
| * </p> |
| * <p> |
| * This would normally be done by contributing the {@link ExtendedUMLResourceFactoryImpl} to the |
| * <code>org.eclipse.emf.ecore.extension_parser</code> extension point. However, in the present case, the Eclipse UML2 |
| * project contributes already the standard {@link UMLResourceFactoryImpl} for *.uml files to the very same extension |
| * point. In order to avoid conflicting contributions of multiple {@link ResourceFactoryImpl resource factory} |
| * implementations for the same file extension, we have to go this way and leverage the fact that the |
| * {@link ResourceSetImpl resource set}'s own {@link ResourceFactoryRegistryImpl resource factory registry} takes always |
| * precedence over the static {@link Resource.Factory.Registry#INSTANCE} where all contributed |
| * {@link ResourceFactoryImpl resource factory} implementations end up. |
