Type Parameters:

I - Vertex index value

V - Vertex value

E - Edge value

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

Write out Edge Value with Source and Destination ID, but not the vertex value. This is a demostration output format to show the possibility to separately output edges from vertices.
