| /** |
| * This is an example of a Semantic model editor. |
| * <!-- begin-user-doc --> |
| * This particular implementation is customized from the default editor generated |
| * by EMF. This editor differs from the default EMF implementation in the following |
| * ways: |
| * <ul> |
| * <li>all instances operate in a single, shared |
| * {@link TransactionalEditingDomain transactional editing domain}</li> |
| * <li>a {@link ResourceSetListener} is statically registered on this editing |
| * domain that automatically creates editors for any resource loaded (e.g., |
| * by proxy resolution)</li> |
| * <li>the editing domain delegates command-stack functionality to the worbench |
| * {@link IOperationHistory}. It provides its {@link IUndoContext} to |
| * specialized implementations of the undo/redo actions that operate on the |
| * operation history. Execution of commands is also delegated to the |
| * operation history</li> |
| * <li>refreshing of the tree content and property sheet is performed within |
| * read-only transactions on the editing domain, using the |
| * {@link TransactionalEditingDomain#runExclusive(Runnable)} API</li> |
| * <li>only the 'selection' tree view is provided (it is not a multi-page editor)</li> |
| * <li>synchronization of the workspace resource with the loaded EMF resource |
| * uses the {@link WorkspaceSynchronizer} utility API</li> |
| * </ul> |
