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

Type Parameters:

I - vertexId type parameter

E - edge type parameter

All Superinterfaces:

VertexIdDataIterator<I,Edge<I,E>>, VertexIdIterator<I>

All Known Implementing Classes:

ByteStructVertexIdEdgeIterator

public interface VertexIdEdgeIterator<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>
extends VertexIdDataIterator<I,Edge<I,E>>

Special iterator that reuses vertex ids and edge objects so that the lifetime of the object is only until next() is called.
