doStart

protected void doStart()
                throws Exception
Specified by:
doStart in class ServiceSupport
Throws:
Exception

doStop

protected void doStop()
               throws Exception

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.

Specified by:
process in interface AsyncProcessor
Parameters:
exchange - the Exchange to process
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:
true if the processing was completed synchronously.

process

public void process(Exchange exchange)
             throws Exception
Description copied from interface: Processor
Processes the message exchange

Specified by:
process in interface Processor
Throws:
Exception - if an internal processing error has occurred.
