public interface Mediator
extends SynapseArtifact

All Synapse mediators must implement this Mediator interface. As a message passes through the Synapse system, each mediator's mediate() method is invoked in the sequence/order defined in the SynapseConfiguration.

It is recommended to extend the abstract class AbstractMediator or the AbstractListMediator as appropriate instead of directly implementing this interface

synCtx - the current message for mediation

Returns:

true if further mediation should continue

getType

This is used for debugging purposes and exposes the type of the current mediator for logging and debugging purposes

Returns:

a String representation of the mediator type

getTraceState

This is used to check whether the tracing should be enabled on the current mediator or not

Returns:

value that indicate whether tracing is on, off or unset

setTraceState
