Handling Exceptional Cases in a CommandGroup

[notmattlythgoe]

What about something like this?

private Command2 timeoutCommand  = new Command2();

public SomethingCommandGroup() {
     addSequential(new Command1());
     addSequential(timeoutCommand, 5);
     addSequential(new Command3());

}

protected boolean isFinished() {
     return super.isFinished()
          || timeoutCommand.isTimedOut();
}

Since a CommandGroup is still a Command you can override isFinished() to finish if a certain command or several have timed out.

I am unsure if the timed out command will need reinitialized or not. My gut says no.
