java.lang.Object

psdi.mbo.iterator.SpecificMboIterator

All Implemented Interfaces:

MboSetIterator

public class SpecificMboIterator
extends java.lang.Object
implements MboSetIterator

This "iterator" actually only visits a single Mbo in the set, specified by it's position. At most, a single call to next will return a non-null value. A 2nd call to next will always return null.
