Class RepresentativeByteStructIterator<T extends org.apache.hadoop.io.Writable>

java.lang.Object

org.apache.giraph.utils.ByteStructIterator<T>

org.apache.giraph.utils.RepresentativeByteStructIterator<T>

Type Parameters:

T - Type that extends Writable that will be iterated

All Implemented Interfaces:

Iterator<T>

public abstract class RepresentativeByteStructIterator<T extends org.apache.hadoop.io.Writable>
extends ByteStructIterator<T>

The objects provided by this iterator have lifetimes only until next() is called. In that sense, the object provided is only a representative object.
