All Implemented Interfaces:

MuleContextAware, Disposable, Initialisable, OutboundRouter, Router

public class EndpointSelector
extends FilteringOutboundRouter

EndpointSelector selects the outgoing endpoint based on a an expression evaluator ("header:endpoint" by default). It will first try to match the endpoint by name and then by address. The endpoints to use can be set on the router itself or be global endpoint definitions.

 <outbound>
      <endpoint-selector-router evaluator="xpath" expression="/MSG/HEADER/NEXT-ADDRESS">
          <endpoint name="dest1" address="jms://queue1" />
          <endpoint name="dest2" address="jms://queue2" />
          <endpoint name="dest3" address="jms://queue3" />
      </endpoint-selector-router>
 </outbound>

route

public MuleMessage route(MuleMessage message,
                MuleSession session,
                boolean synchronous)
                  throws RoutingException

Description copied from interface: OutboundRouter

This method is responsible for routing the Message via the MuleSession. The logic for this method will change for each type of router depending on expected behaviour. For example, a MulticastingRouter might just iterate through the list of assoaciated endpoints sending the message. Another type of router such as the ExceptionBasedRouter will hit the first endpoint, if it fails try the second, and so on. Most router implementations will extends the FilteringOutboundRouter which implements all the common logic need for a router.

Specified by:

route in interface OutboundRouter

Overrides:

route in class FilteringOutboundRouter

Parameters:

message - the message to send via one or more endpoints on this router

session - the session used to actually send the event

synchronous - whether the invocation process should be synchronous or not

Returns:

a result message if any from the invocation. If the synchronous flag is false a null result will always be returned.

Throws:

RoutingException
