Class ByteStructVertexIdEdgeIterator<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>

java.lang.Object

org.apache.giraph.utils.ByteStructVertexIdIterator<I>

org.apache.giraph.utils.ByteStructVertexIdDataIterator<I,Edge<I,E>>

org.apache.giraph.utils.ByteStructVertexIdEdgeIterator<I,E>

Type Parameters:

I - vertexId type parameter

E - edge type parameter

All Implemented Interfaces:

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

public class ByteStructVertexIdEdgeIterator<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>
extends ByteStructVertexIdDataIterator<I,Edge<I,E>>
implements VertexIdEdgeIterator<I,E>

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