A more complex version of Processor which supports asynchronous processing of the Exchange. Any processor can be coerced to have an AsyncProcessor interface by using the AsyncProcessorTypeConverter.covert method.

Method Detail

process

boolean process(Exchange exchange,
                AsyncCallback callback)

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

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.
