Processor
public boolean process(Exchange exchange, AsyncCallback callback)
AsyncProcessor
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

exchange
- the message exchangecallback
- 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.public List<Processor> next()
