Public Member Functions inherited from edbee::Change
virtual	~Change ()
	a virtual empty destructor
virtual bool	canUndo ()
	This method should return true if the change can be reverted.
virtual bool	isPersistenceRequired ()
	This flag is used to mark this stack item as non-persistence requirable The default behaviour is that every textchange requires persistence. It is also possible to have certain changes that do not require persitence but should be placed on the undo stack.
virtual TextEditorController *	controllerContext ()
	A text command can belong to a controller/view When it's a view only command. The undo only applies only to this view warning a DOCUMENT change may NEVER return a controllerContext!!
bool	isDocumentChange ()
	this method can be used to check if the given change is a document change
virtual bool	isGroup ()
	This method returns true if this change is a group change. When an object is group change it should be inherited by TextChangeGroup.
