| Method Detail |
protected boolean prepare()
AbstractCommandAbstractCommand.canExecute() to give the command an opportunity to ready itself for execution.
The returned value is stored in AbstractCommand.canExecute().
In other words, you can override this method to initialize
and to yield a cached value for the all subsequent calls to canExecute.
prepare in class AbstractCommandpublic void execute()
Commandexecute when canExecute returns false,
or when canExecute hasn't been called, is undefined.

Commandredo the effect after undoing the effect.
The effect, if any, of calling redo before undo is called is undefined.
Note that if you implement redo to call execute
then any derived class will be restricted by that decision also.
