public abstract class DGAAbstractEdgeOutputFormat<I extends WritableComparable,V extends Writable,E extends Writable>
extends TextEdgeOutputFormat<I,V,E>

The EdgeTDTOutputFormat outputs the edges that make up our graph.

This output format will allow users to write out the source vertex ID, the destination vertex ID, and optionally, the vertex value and/or the edge value, using an optionally defined field delimiter (defaults to ,)
