Method Detail

smStateChanged

void smStateChanged(SimpleStateMachine sm,
                    SMStateIF state)

Called every time a state added or changed

Parameters:

sm - the state machine containing the state

state - the state

smTransitionAdded

void smTransitionAdded(SimpleStateMachine sm,
                       SMStateIF origState,
                       java.lang.Class triggerEventCls,
                       StateTransition transition,
                       SMStateIF newState)

Called every time a transition added. Look at addTransition method for the details about the parameters

smStateEntry

void smStateEntry(SimpleStateMachine sm,
                  SMStateIF state)

Called every time a state becomes current

Parameters:

sm - containing SM

state - the new current state

smStateExit

void smStateExit(SimpleStateMachine sm,
                 SMStateIF state)

Called every time a current state changes to other state

Parameters:

sm - containing SM

state - the old current state

smHandledEvent

void smHandledEvent(SimpleStateMachine sm,
                    SMStateIF origState,

                    StateTransition transition,
                    SMStateIF newState)

Called every time a transition performed. newState is the actual state that will be set current. Look at addTransition method for the details about the parameters

smStateEntryTransAdded
