Subject Re: Custom state values in CEP
Date Fri, 22 Apr 2016 09:05:39 GMT
Hi Sowmya,

I'm afraid at the moment it is not possible to store custom state in the
filter or select function. If you need access to the whole sequence of
matching events then you have to put this code in the select clause of your
pattern stream.

Cheers,
Till
