Method Summary

boolean	doCommand(DoCommand cmd) Process a command if this command makes sense for this object (the target is is expected).

Method Detail

setState

boolean setState(State s)

Listeners should be careful that the s's ident matches what they are expecting and disregard all other state events.
This implementation provides advantages and disadvantages. The advantage is that you don't need to register for the right states, all states are fired at you and you can monitor what is going on around you.
The disadvantage is that this may add overhead and it is a potential pitfall.

Parameters:

s -

Returns:

true if anything changed.

doCommand

boolean doCommand(DoCommand cmd)
