Class SequenceMediator

java.lang.Object

org.apache.synapse.mediators.AbstractMediator

org.apache.synapse.mediators.AbstractListMediator

org.apache.synapse.mediators.base.SequenceMediator

All Implemented Interfaces:

AspectConfigurable, ManagedLifecycle, Mediator, ListMediator, Nameable, SynapseArtifact

public class SequenceMediator
extends AbstractListMediator
implements Nameable

The Sequence mediator either refers to a named Sequence mediator instance or is a *Named* list/sequence of other (child) Mediators

If this instance defines a sequence mediator, then the name is required, and an errorHandler sequence name optional. If this instance refers to another (defined) sequence mediator, the errorHandler will not have a meaning, and if an error in encountered in the referred sequence, its errorHandler would execute.

SequenceMediator

public SequenceMediator()

Method Detail

mediate

public boolean mediate(MessageContext synCtx)

If this mediator refers to another named Sequence, execute that. Else execute the list of mediators (children) contained within this. If a referenced named sequence mediator instance cannot be found at runtime, an exception is thrown. This may occur due to invalid configuration of an erroneous runtime change of the synapse configuration. It is the responsibility of the SynapseConfiguration builder to ensure that dead references are not present.

Specified by:

mediate in interface Mediator

Overrides:

mediate in class AbstractListMediator

Parameters:

synCtx - the synapse message

Returns:

as per standard mediator result

init

public void init(SynapseEnvironment se)

This method will ensure that each and every sequence wil only be initialized atmost once

Specified by:

init in interface ManagedLifecycle

Overrides:

init in class AbstractListMediator

Parameters:

se - - enviorenment to be initialized

destroy

public void destroy()

Description copied from class: AbstractListMediator

Destroy child mediators recursively

Specified by:

destroy in interface ManagedLifecycle

Overrides:

destroy in class AbstractListMediator

getName
