Method Detail

canMoveShape

public boolean canMoveShape(IMoveShapeContext context)
Description copied from interface: IMoveShape
Can move shape.

Parameters:
context - the context
Returns:
true, if successful

moveShape

public void moveShape(IMoveShapeContext context)
Description copied from interface: IMoveShape
Move shape.

Specified by:
moveShape in interface IMoveShape
Parameters:
context - the context

canUndo

public boolean canUndo(IContext context)
Description copied from interface: IFeature
Decides if the current feature can be undone - this is the undo of the execute operation.

Specified by:
canUndo in interface ICustomUndoableFeature
Specified by:
canUndo in interface IFeature
Overrides:
canUndo in class AbstractFeature
Parameters:
context - this is the general input for this method

IContext

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