Method Detail

beforePhaseExecution

public boolean beforePhaseExecution(LifecyclePhase phase,
                                    Object object)

Description copied from interface: LifecycleInterceptor

Invoked before the given phase is applied over the object.

This method's return value also indicates if the lifecycle should in fact be applied over the object or if it should be skipped. Note that this interceptor is not responsible from actually preventing the phase from being applied. It's the invoker's responsibility to skip the object if the interceptor indicates so.

Specified by:

beforePhaseExecution in interface LifecycleInterceptor

Parameters:

phase - the phase being applied

object - the target object

Returns:

always returns true

afterPhaseExecution

public void afterPhaseExecution(LifecyclePhase phase,
                                Object object,

NoOp implementation

Specified by:

afterPhaseExecution in interface LifecycleInterceptor

Parameters:

phase - the phase that was applied

object - the target object
