Method Detail

onEvent

public State<T> onEvent(T stateful,
                        String event,
                        Object... parms)
                 throws TooBusyException

Description copied from class: FSM

Process event. Will handle all retry attempts. If attempts exceed maximum retries, it will throw a TooBusyException.

Overrides:

onEvent in class FSM<T>

Parameters:

stateful - The Stateful Entity

event - The Event

parms - Optional parameters to pass into the Action

Returns:

The current State

Throws:

TooBusyException - Exception indicating that we've exceeded the number of RetryAttempts

transition

protected State<T> transition(T stateful,
                              State<T> current,
                              String event,
                              Transition<T> t,
                              Object... args)
                       throws RetryException

Overrides:

transition in class FSM<T>

Throws:

RetryException
