Class DefaultFeatureCommandsStack

java.lang.Object

org.gvsig.tools.undo.command.impl.DefaultUndoRedoCommandStack

org.gvsig.fmap.dal.feature.impl.undo.DefaultFeatureCommandsStack

All Implemented Interfaces:

FeatureCommandsStack, Observable, WeakReferencingObservable, UndoRedoCommandStack, UndoRedoStack

public class DefaultFeatureCommandsStack
extends DefaultUndoRedoCommandStack
implements FeatureCommandsStack

Clase en memoria para registrar y gestionar los comandos que vamos realizando. La forma en que ha sido implementada esta clase, en vez de una única lista para albergar los comandos de deshacer(undos) y los de rehacer(redos), se ha optado por dos pilas una para deshacer(undos) y otra para rehacer(redos), de esta forma : Cuando se añade un nuevo comando, se inserta este a la pila de deshacer(undos) y se borra de la de rehacer(redos). Si se realiza un deshacer se desapila este comando de la pila deshacer(undos) y se apila en la de rehacer(redos). Y de la misma forma cuando se realiza un rehacer se desapila este comando de la pila de rehacer(redos) y pasa a la de deshacer(undos).
