Hi, I wrote a transform class in Siddhi which i wanted to return variable number of parameters depending on the # of input parameters. So I got the input stream definition in init method to find out number of input parameters and added attributes to out put stream depending on that.
but I found that when siddhi query returns the out put , it only takes the output stream parameters which are added in the constructor. I found that siddhi call updateQueryEventSourceOutDefinition method when adding query. package org.wso2.siddhi.core.util.parser; StreamParser.java In this method it only make instance of the Transformer class , but not call the init method. So i can not add attributes to out stream when called in side init method in a Transform class. Please advice me on this. Waruna
