public class EvaluateExpressionProcessor extends Object implements AsyncProcessor, Traceable
Processor which evaluates an Expression
and stores the result as a property on the Exchange with the key
Exchange.EVALUATE_EXPRESSION_RESULT.
This processor will in case of evaluation exceptions, set the caused exception
on the Exchange.| Constructor and Description |

AsyncProcessorProcessor.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.process in interface AsyncProcessorexchange - 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 String getTraceLabel()
