Retrieve data from org.wso2.siddhi.core.event.Event class

I have an output stream whose definition is define stream outStream (deviceID string, val int).

In the 'receive' method of its callback, I want to do some processing with the val(of type int). Is there any method to retrieve this integer value from the Event object?

I tried to retrieve it using "events[i].getData().toString()", but the string returned is "[Ljava.lang.Object;@c55cfc" and i can't make any sense of it. (Here, 'events' is the array of 'Events' passed in to the 'receive' method of the callback)

Thanks in advance for any assistance.

getData() method of Event class returns an Object[]. That means, you'll be calling toString() on an Object[]. In Java, that'll print the class name + hashcode of the object (Ljava.lang.Object;@c55cfc) (refer to this for more info). So, if you need to get the values instead, simply iterate through the Object[] returned by getData() method. (i.e events[i].getData()[j])
