sendMessages

public void sendMessages(Vertex<K,Double> vertex)

Description copied from class: ScatterFunction

This method is invoked once per superstep for each vertex that was changed in that superstep. It needs to produce the messages that will be received by vertices in the next superstep.

Specified by:

sendMessages in class ScatterFunction<K,Double,Double,Double>

Parameters:

vertex - The vertex that was changed.
