Method Detail

beforeTransition

void beforeTransition(FSMTransitionEvent e)
               throws IllegalStateException

A method to be called BEFORE the specified transition takes place. Since the transition still has to happen, no listener can be sure that the event notification eventually leads to the transition. This is because the state machine process can fail after the notice, or the target state can be prevented somehow.

Parameters:

e - The transition that will be attempted.

Throws:

IllegalStateException - on failure.

transitionPerformed

void transitionPerformed(FSMTransitionEvent e)

A method to be called AFTER the specified transition is done.

Parameters:

e - The transition that was made.
