Class FlowStatusChangeListenerWrapperTransformer<T>

java.lang.Object

com.neurosys.events.ChangeListenerWrapperTransformer<SynchronousFlowStatusChange<T,List<Status>>>

com.neurosys.events.FlowStatusChangeListenerWrapperTransformer<T>

Type Parameters:

T - as core event object

All Implemented Interfaces:

ChangeListener<SynchronousFlowStatusChange<T,List<Status>>>, ChangeListenerTransfomer<SynchronousFlowStatusChange<T,List<Status>>>, Serializable, EventListener, org.apache.commons.collections.Transformer

public class FlowStatusChangeListenerWrapperTransformer<T>
extends ChangeListenerWrapperTransformer<SynchronousFlowStatusChange<T,List<Status>>>

A convenience extension of ChangeListenerWrapperTransformer that accepts only SynchronousOperationChange type events and if the ChangeListenerWrapperTransformer.getTransformer() transformation is successful then adds a Status INFO level or ERROR level to the feedback.
