There is a StatementAwareUpdateListener interface that delivers the statement object together with EventBean output.
Esper EventBean and EPStatement Association
سؤال
Is there anyway to relate the output of an Esper EventBean object back to the original EPStatement that produced the result using Java?
I have a number of EPStatements defined that use the @Name annotation but I noticed that this value is not present in the resulting EventBean. I need this value so I can uniquely identify the EventBeans that are produced.
Alternatively, is there is some way to attach an additional field that will be present in a resulting EventBean object after Esper outputs a result? This would also work for my use case.
