Thomas Bernhardt commented on ESPER-580:
----------------------------------------
It seems that update listener code could also assign a row number.
What is the advantage of having an EPL function?
> rownum() function

> A function for numbering the events when a listener gets invoked. In this version of the function, the numbering should start over again, everytime the update listener gets invoked. The numbering should be based on ordering or on event arrival. The start (0,1,2..n) of the numbering should be configurable as well as the increment.
