Detailed Description

Map undo step which deletes the referenced objects.

Take care of correct application order when mixing with an add step to make sure that the object indices are preserved.

Member Function Documentation

getModifiedObjects()

void OpenOrienteering::DeleteObjectsUndoStep::getModifiedObjects ( int  part_index, ObjectSet &  out  ) const

overridevirtual

Adds the list of the step's modified objects to the container provided by out.

Only adds objects when the given part_index matches this step's part index.

Reimplemented from OpenOrienteering::ObjectModifyingUndoStep.

getModifiedParts()

bool OpenOrienteering::DeleteObjectsUndoStep::getModifiedParts ( PartSet &  out ) const

overridevirtual

Adds the the step's modified part to the container provided by out.

Returns

True if there are objects modified by this undo step, false otherwise.

Reimplemented from OpenOrienteering::ObjectModifyingUndoStep.

undo()

UndoStep * OpenOrienteering::DeleteObjectsUndoStep::undo ( )

overridevirtual

Undoes the action and returns a new UndoStep.

The returned UndoStep can redo the action again.

Implements OpenOrienteering::UndoStep.
