java.lang.Object

org.apache.synapse.FaultHandler

Direct Known Subclasses:

AbstractEndpoint, DynamicLoadbalanceFaultHandler, MediatorFaultHandler

public abstract class FaultHandler
extends Object

This is an abstract class that handles an unexpected error during Synapse mediation, but looking at the stack of registered FaultHanders and invoking on them as appropriate. Sequences and Endpoints would be Synapse entities that handles faults. If such an entity is unable to handle an error condition, then a SynapseException should be thrown, which triggers this fault handling logic.
