Detailed Description

An undo step which does nothing.

Its validness depends on the argument given to the constructor. It always returns a valid NoOpUndoStep from undo().

This class is used to catch unknown types of undo step when loading files from newer version of Mapper. Another use is unit-testing the UndoManager.

Constructor & Destructor Documentation

OpenOrienteering::NoOpUndoStep::NoOpUndoStep	(	Map *	map,
