All Implemented Interfaces:

AsyncProcessor, Navigate<Processor>, Processor, LoadBalancer, Service, ShutdownableService, StatefulService, SuspendableService

public abstract class SimpleLoadBalancerSupport
extends LoadBalancerSupport

A default base class for a LoadBalancer implementation.

This implementation is dedicated for simple synchronous load balancers.

Consider using the LoadBalancerSupport if you want to support the asynchronous routing engine in Camel.

Method Detail

process

public boolean process(Exchange exchange,
              AsyncCallback callback)

Description copied from interface: AsyncProcessor

Processes the message exchange. Similar to Processor.process(org.apache.camel.Exchange), but the caller supports having the exchange asynchronously processed.

If there was a failure processing then the caused Exception would be set on the Exchange.

Parameters:

exchange - the message exchange

callback - the AsyncCallback will be invoked when the processing of the exchange is completed. If the exchange is completed synchronously, then the callback is also invoked synchronously. The callback should therefore be careful of starting recursive loop.

Returns:

(doneSync) true to continue execute synchronously, false to continue being executed asynchronously

process

public abstract void process(Exchange exchange)
                      throws Exception

Description copied from interface: Processor

Processes the message exchange

Specified by:

process in interface Processor

Overrides:

process in class LoadBalancerSupport

Parameters:

exchange - the message exchange

Throws:

Exception - if an internal processing error has occurred.
