Class IdempotentMessageValidator

java.lang.Object

org.mule.runtime.api.meta.AbstractAnnotatedObject

org.mule.runtime.core.routing.IdempotentMessageValidator

All Implemented Interfaces:

Function<org.reactivestreams.Publisher<Event>,org.reactivestreams.Publisher<Event>>, org.mule.runtime.api.lifecycle.Disposable, org.mule.runtime.api.lifecycle.Initialisable, org.mule.runtime.api.meta.AnnotatedObject, FlowConstructAware, MuleContextAware, Processor, ReactiveProcessor

Direct Known Subclasses:

IdempotentSecureHashMessageValidator

public class IdempotentMessageValidator
extends org.mule.runtime.api.meta.AbstractAnnotatedObject
implements Processor, MuleContextAware, FlowConstructAware, org.mule.runtime.api.lifecycle.Initialisable, org.mule.runtime.api.lifecycle.Disposable

IdempotentMessageValidator ensures that only unique messages are passed on. It does this by checking the unique ID of the incoming message. Note that the underlying endpoint must support unique message IDs for this to work, otherwise a UniqueIdNotSupportedException is thrown.
