public IResizeConfiguration getResizeConfiguration(IResizeShapeContext context)
Description copied from interface: IResizeFeature
Provides configuration object, which describes the resize behavior

Specified by:
getResizeConfiguration in interface IResizeFeature

getResizeConfiguration in class DefaultResizeShapeFeature
Parameters:
context - the resizing context
Returns:
configuration object

canUndo

public boolean canUndo(IContext context)

undo

public void undo(IContext context)
Description copied from interface: ICustomUndoableFeature
This method will be called to actually do the work needed for undo. Customers may revert their non-EMF changes done by the feature here.

Specified by:
undo in interface ICustomUndoableFeature
Parameters:
context - this is the instance of the IContext object that was in use when executing the feature
Since:
0.8

canRedo

public boolean canRedo(IContext context)
Description copied from interface: ICustomUndoableFeature
Decides if the processed feature can be re-done.

Note that as soon as any feature reports false here, also all consecutive entries in the command stack are no longer reachable for redo.

Specified by:
canRedo in interface ICustomUndoableFeature
Parameters:
context - this is the instance of the IContext object that was in use when executing the feature
Returns:
true if the feature can be re-done, false if not
Since:
0.8

redo

public void redo(IContext context)
Description copied from interface: ICustomUndoableFeature
This method will be called to actually do the work needed for redo. Customers may re-apply their non-EMF changes done by the feature here. (Usually it might be sufficient to delegate to the execution method of the feature.)

Specified by:

Parameters:
context - this is the instance of the IContext object that was in use when executing the feature
Since:
