"some sort of" decision handler.
I mean that, when you do a signal without a transition name, it will do a
getDefaultLeavingTransition on the node (check the sourcecode for this). It
would be nice if this function also calls a handler, similar to a
DecisionHandler, which returns the name of the transition that should be
consequently used in the signal.
| In token:
| public void signal() {
| if ( (node == null) || (node.getDefaultLeavingTransition() == null)) {
| throw new IllegalStateException("couldn't signal token '" + this + "'
: couldn't leave node '" + node + "' over its default transition");
| }
| signal(node.getDefaultLeavingTransition());
| }
|
| In node:
|
| public Transition getDefaultLeavingTransition() {
| Transition defaultTransition = null;
| if ( (leavingTransitions!=null)
| && (leavingTransitions.size()>0) ) {
| // here you could check for the existence of a handler, and use this
| // if it returns null, you could still use the rest of the code, giving
back the first one
| defaultTransition = (Transition) leavingTransitions.get(0);
| } else if ( superState!=null ){
| defaultTransition = superState.getDefaultLeavingTransition();
| }
| return defaultTransition;
| }
|
| ....
