Method Detail

doStart

protected void doStart()

Description copied from class: LifecycleObjectSupport

Subclasses may implement this method with the start behavior. This method will be invoked while holding the LifecycleObjectSupport.lifecycleLock.

Overrides:

doStart in class LifecycleObjectSupport

setBeanName

public void setBeanName(java.lang.String name)

Specified by:

setBeanName in interface org.springframework.beans.factory.BeanNameAware

getBeanName

protected java.lang.String getBeanName()

Returns a bean name known to context per contract with BeanNameAware.

Returns:

a bean name

getStateMachineEventPublisher

protected StateMachineEventPublisher getStateMachineEventPublisher()

Gets the state machine event publisher.

Returns:

the state machine event publisher

setStateMachineEventPublisher

public void setStateMachineEventPublisher(StateMachineEventPublisher stateMachineEventPublisher)

Sets the state machine event publisher.

Parameters:

stateMachineEventPublisher - the new state machine event publisher

setContextEventsEnabled

public void setContextEventsEnabled(boolean contextEventsEnabled)

Set if context application events are enabled. Events are enabled by default. Set this to false if you don't want state machine to send application context events.

Parameters:

contextEventsEnabled - the enabled flag
