Package org.apache.synapse.mediators.eip.splitter

Class IterateMediator

java.lang.Object

org.apache.synapse.mediators.AbstractMediator

org.apache.synapse.mediators.eip.splitter.IterateMediator

All Implemented Interfaces:

AspectConfigurable, ManagedLifecycle, Mediator, FlowContinuableMediator, SynapseArtifact

public class IterateMediator
extends AbstractMediator
implements ManagedLifecycle, FlowContinuableMediator

Splits a message using an XPath expression and creates a new message to hold each resulting element. This is very much similar to the clone mediator, and hands over the newly created messages to a target for processing
