Message class in Hama Graph

[Ηλίας Τριχόπουλος <it...@csd.auth.gr>]

Hello everyone,

I am new in developing with Hama and generally with BSP model.
The Vertex interface expects an argument "M" that defines the message class. In my class that extends the Vertex class, I am using the sendMessageToNeighboors method (inside the compute method). The sendMessageToNeighboors method expects the same argument type as the Vertex class for the message. During the computation (in different supersteps) I want to be able to send different kind of messages.
Is this somehow possible?

Thank you,

Thanks for your support!

I finally came up with the same idea, I will try it and see what happens

With current implementation, if the messages sent are of same type per
superstep, you can also define a base class for defining the message class
and the API. The messages sent and received could be derived classes. Off
course this would involve some casting.

You can use MapWritable to send different type messages among processors.
