org.apache.giraph.edge

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

Type Parameters:

I - Vertex index

E - Edge value

All Superinterfaces:

Edge<I,E>, MutableEdge<I,E>

All Known Implementing Classes:

DefaultEdge, EdgeNoValue

public interface ReusableEdge<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>
extends MutableEdge<I,E>

A complete edge, the target vertex and the edge value. Can only be one edge with a destination vertex id per edge map. This edge can be reused, that is you can set it's target vertex ID and edge value. Note: this class is useful for certain optimizations, but it's not meant to be exposed to the user. Look at MutableEdge instead.
