|

51 | * rehacer(redos), se ha optado por dos pilas una para deshacer(undos) y otra

52 | * para rehacer(redos), de esta forma : Cuando se a?ade un nuevo comando, se
|
||
53 | * inserta este a la pila de deshacer(undos) y se borra de la de rehacer(redos).
|
||
54 | * Si se realiza un deshacer se desapila este comando de la pila deshacer(undos)
|
||
55 | * y se apila en la de rehacer(redos). Y de la misma forma cuando se realiza un
|
||
56 | * rehacer se desapila este comando de la pila de rehacer(redos) y pasa a la de
|
||
57 | * deshacer(undos).
