Class PairList.Iterator

java.lang.Object

org.apache.giraph.utils.PairList.Iterator

Enclosing class:

PairList<U,V>

public class PairList.Iterator
extends Object

Special iterator class which we'll use to iterate through elements of PairList, without having to create new object as wrapper for each pair. Protocol is somewhat similar to the protocol of Iterator only here next() doesn't return the next object, it just moves along in the collection. Values related to current pair can be retrieved by calling getCurrentFirst() and getCurrentSecond() methods. Not thread-safe.
