Class ValueFactories<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>

java.lang.Object

org.apache.giraph.factories.ValueFactories<I,V,E>

Type Parameters:

I - Vertex id

V - Vertex data

E - Edge data

public class ValueFactories<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>
extends Object

Holder for factories to create user types. Note that we don't store the MessageValueFactory here because they reference types which may change at a given superstep. Instead we create them as necessary so that they get the latest information.
