Interface StrictRandomAccessOutEdges<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>

Type Parameters:

I - Vertex id

E - Edge value

All Superinterfaces:

Iterable<Edge<I,E>>, OutEdges<I,E>, org.apache.hadoop.io.Writable

All Known Implementing Classes:

HashMapEdges, LongByteHashMapEdges, LongDoubleHashMapEdges, LongNullHashSetEdges

public interface StrictRandomAccessOutEdges<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>
extends OutEdges<I,E>

Interface for OutEdges implementations that provide efficient random access to the edges given the target vertex id. This version is for strict graphs (i.e. assumes no parallel edges).

Method Summary

Modifier and Type	Method and Description
E	getEdgeValue(I targetVertexId) Return the edge value for the given target vertex id (or null if there is no edge pointing to it).
void	setEdgeValue(I targetVertexId, E edgeValue) Set the edge value for the given target vertex id (if an edge to that vertex exists).
