Emitting Custom Object as Tuple from spout

[Ankur Garg]

Hi ,

I am new to apache Storm . To understand it I was looking at storm examples
provided in the storm tutorial (
https://github.com/apache/storm/tree/master/examples/storm-starter)  .


In all the examples , we are emitting prmitive types (String,int etc) as
Tuples .

In my use case I am having a Java Object which i want to emit as tuple to
bolts .

I am not sure how to do it . It seems I have to implement a custom Tuple
producer to convert java Object to Values .

Can anyone provide me some example how to do that :

For ex my Java Object is :

class Bean
{
    int A ;
    String B;
     Bean2 b;
   //setters and getters

}

and Class Bean2
{
   //Some Attributes
}

Now , in my nextTuple() method for Spout , I have an instance of Bean
object .

How do I translate into Tuple and emit it and consume it through my bolt.

Any ideas please.

Thanks
