execute()

bool Command::execute ( )

virtual

the command is executed a first time after its registration for undo redo, then on redo

Execute may induce subcommands to be registered during its execution. Subcommands must be deleted before redo, to be recreated by redo. CommandDestroy is a special case, where subcommands are registered before Execute, and undo action calls executeSubOnly instead of reverse. Subcommands pf CommandDestroy must not be deleted.
