canResizeShape
Description copied from interface:IResizeShapeCan resize shape.- Specified by:
canResizeShapein interfaceIResizeShape- Overrides:
canResizeShapein classDefaultResizeShapeFeature- Parameters:
context- the context- Returns:
- true, if successful
-
resizeShape
Description copied from interface:IResizeShapeResize shape.- Specified by:
resizeShapein interfaceIResizeShape- Overrides:
resizeShapein classDefaultResizeShapeFeature- Parameters:
context- the context
-
getResizeConfiguration
Description copied from interface:IResizeFeatureProvides configuration object, which describes the resize behavior- Specified by:
getResizeConfigurationin interfaceIResizeFeature- Overrides:
getResizeConfigurationin classDefaultResizeShapeFeature- Parameters:
context- the resizing context- Returns:
- configuration object
-
isAbort
public boolean isAbort()Description copied from interface:ICustomAbortableUndoRedoFeatureThe Graphiti framework will call this method afterICustomUndoRedoFeature.preUndo(org.eclipse.graphiti.features.context.IContext)/ICustomUndoRedoFeature.preRedo(org.eclipse.graphiti.features.context.IContext)have been called and before the actual undo/redo operation is triggered. In case this method returnstrue, the operation will be cancelled by the Graphiti framework by throwing anOperationCanceledExceptionthat causes am EMF revert of the operation.Implementing classes might e.g. set a flag in
ICustomUndoRedoFeature.preUndo(org.eclipse.graphiti.features.context.IContext)/ICustomUndoRedoFeature.preRedo(org.eclipse.graphiti.features.context.IContext)as cancellation indication and check that that flag here.- Specified by:
isAbortin interfaceICustomAbortableUndoRedoFeature- Returns:
truein case you want to cancel the current operation,falseotherwise.- Since:
- 0.12
-
canUndo
Description copied from interface:IFeatureDecides if the current feature can be undone - this is the undo of the execute operation.- Specified by:
canUndoin interfaceICustomUndoRedoFeature- Specified by:
canUndoin interfaceIFeature- Overrides:
canUndoin classAbstractFeature- Parameters:
context- this is the general input for this method- Returns:
- true if the feature can be undone, false if not
- See Also:
-
preUndo
Description copied from interface:ICustomUndoRedoFeatureThis method will be called by the Graphiti framework before the EMF undo is triggered. Customers may revert their non-EMF changes done by the feature here or inICustomUndoRedoFeature.postUndo(IContext).- Specified by:
preUndoin interfaceICustomUndoRedoFeature- Parameters:
context- this is the instance of theIContextobject that was in use when executing the feature- Since:
- 0.12
-
postUndo
Description copied from interface:ICustomUndoRedoFeatureThis method will be called by the Graphiti framework after the EMF undo is finished. Customers may revert their non-EMF changes done by the feature here or inICustomUndoRedoFeature.preUndo(IContext).- Specified by:
postUndoin interfaceICustomUndoRedoFeature- Parameters:
context- this is the instance of theIContextobject that was in use when executing the feature- Since:
- 0.12
-
canRedo
Description copied from interface:ICustomUndoRedoFeatureDecides if the processed feature can be re-done. This method is called once by the Graphiti framework just before any redo work is started, e.g. beforeICustomUndoRedoFeature.preRedo(IContext).Note that as soon as any feature reports
falsehere, also all consecutive entries in the command stack are no longer reachable for redo.- Specified by:
canRedoin interfaceICustomUndoRedoFeature- Parameters:
context- this is the instance of theIContextobject that was in use when executing the feature- Returns:
- true if the feature can be re-done, false if not
- Since:
- 0.8
-
preRedo
Description copied from interface:ICustomUndoRedoFeatureThis method will be called by the Graphiti framework before the EMF undo has triggered. Customers may re-apply their non-EMF changes done by the feature here or inICustomUndoRedoFeature.postRedo(IContext). (Usually it might be sufficient to delegate to the execution method of the feature.)- Specified by:
preRedoin interfaceICustomUndoRedoFeature- Parameters:
context- this is the instance of theIContextobject that was in use when executing the feature- Since:
- 0.12
-
postRedo
Description copied from interface:ICustomUndoRedoFeatureThis method will be called by the Graphiti framework after the EMF undo has finished. Customers may re-apply their non-EMF changes done by the feature here or inICustomUndoRedoFeature.preRedo(IContext). (Usually it might be sufficient to delegate to the execution method of the feature.)- Specified by:
postRedoin interfaceICustomUndoRedoFeature- Parameters:
context- this is the instance of theIContextobject that was in use when executing the feature- Since:
- 0.12
