CommandChangeDescription(Command command)
Initializes me with the command that I encapsulate. |
Method Summary | |
---|---|
void |
apply()
I apply my change by undoing the encapsulated operation. |
void |
applyAndReverse()
I apply-and-reverse by alternately undoing and redoing the encapsulated operation. |
boolean |
canApply()
I can apply if my wrapped command can undo or redo, according to whether it was last undone or redone. |
Command |
chain(Command newCommand)
Chains a new command onto the command that I encapsulate, returning the chained result. |

dispose()
Forgets my operation and clears my reference to the adaptable. |
