|

25 | * Clase en memoria para registrar y gestionar los comandos que vamos
|
||
26 | * realizando. La forma en que ha sido implementada esta clase, en vez de una
|
||
27 | * ?nica lista para albergar los comandos de deshacer(undos) y los de
|
||
28 | * rehacer(redos), se ha optado por dos pilas una para deshacer(undos) y otra
|
||
29 | * para rehacer(redos), de esta forma : Cuando se a?ade un nuevo comando, se
|
||
30 | * inserta este a la pila de deshacer(undos) y se borra de la de rehacer(redos).
|
||
31 | * Si se realiza un deshacer se desapila este comando de la pila deshacer(undos)
|
||
32 | * y se apila en la de rehacer(redos). Y de la misma forma cuando se realiza un
|
||
33 | * rehacer se desapila este comando de la pila de rehacer(redos) y pasa a la de
|
||
34 | * deshacer(undos).
