MoveShapeFeatureForPattern

public MoveShapeFeatureForPattern(IFeatureProvider featureProvider,
                                  IPattern pattern)

Creates a new MoveShapeFeatureForPattern.

Parameters:

featureProvider - the feature provider

pattern - the pattern

Method Detail

canMoveShape

public boolean canMoveShape(IMoveShapeContext context)

Description copied from interface: IMoveShape

Can move shape.

Specified by:

canMoveShape in interface IMoveShape

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

Returns:

true if the feature can be undone, false if not

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
