Method Detail


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.

Specified by:
process in interface AsyncProcessor
process in class DelegateAsyncProcessor
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.
(doneSync) true to continue execute synchronously, false to continue being executed asynchronously

public String getTraceLabel()
Description copied from interface: Traceable
Gets the trace label used for logging when tracing is enabled.

The label should be short and precise.
