preStateActivate

public void preStateActivate(State state)

Description copied from interface: StateMachineListener

Invoked just prior to activating a state.

Specified by:

preStateActivate in interface StateMachineListener

postStateActivate

public void postStateActivate(State state)

Description copied from interface: StateMachineListener

Invoked just after activating a state.

Specified by:

postStateActivate in interface StateMachineListener

preStateDeactivate

public void preStateDeactivate(State state)

Description copied from interface: StateMachineListener

Invoked just prior to de-activating a state.

Specified by:

preStateDeactivate in interface StateMachineListener

postStateDeactivate

public void postStateDeactivate(State state)

Description copied from interface: StateMachineListener

Invoked just after de-activating a state.

Specified by:

postStateDeactivate in interface StateMachineListener

eventHandlingError

public void eventHandlingError(Event event,
                               Throwable throwable)

Description copied from interface: StateMachineListener

Invoked whenever an unexpected error occurs running an action in response to an event. This could include an unexpected error in another StateMachineListener or such things as multiple ambiguous actions being applicable for a certain event.

Specified by:

eventHandlingError in interface StateMachineListener

eventEnabledStateEvaluationError

public void eventEnabledStateEvaluationError(Throwable throwable)

Description copied from interface: StateMachineListener

Invoked whenever an unexpected error occurs trying to determine the enabled state of any of the events types in the state machine. The likely cause of this is a failed Condition evaluation.

Specified by:

eventEnabledStateEvaluationError in interface StateMachineListener

eventTypeEnabledStateChanged

public void eventTypeEnabledStateChanged(EventType event_type,
                                         boolean is_enabled)

Description copied from interface: StateMachineListener

Invoked whenever the StateMachine figures out that events of a particular EventType become enabled or disabled.

Specified by:

eventTypeEnabledStateChanged in interface StateMachineListener

stateMachineStopped

public void stateMachineStopped()

Description copied from interface: StateMachineListener

Invoked when the StateMachine transitions to a stop state.

Specified by:

stateMachineStopped in interface StateMachineListener
