Class VertexMessageIterable<V,T>

java.lang.Object

org.apache.hama.graph.VertexMessageIterable<V,T>

All Implemented Interfaces:

Iterable<T>

public final class VertexMessageIterable<V,T>
extends Object
implements Iterable<T>

The rationale behind this class is that it polls messages if they are requested and once it finds a message that is not dedicated for this vertex, it breaks the iteration. The message that was polled and doesn't belong to the vertex is returned by getOverflowMessage().
