/**
 * PartIterator provides access to these objects sequentially, one at a time.
 * The purpose of all Iterators is to to offer a way for OSID methods to
 * return multiple values of a common type and not use an array.  Returning an
 * array may not be appropriate if the number of values returned is large or
 * is fetched remotely.     Iterators do not allow access to values by index,
 * rather you must access values in sequence. Similarly, there is no way to go
 * backwards through the sequence unless you place the values in a data
 * structure, such as an array, that allows for access by index.
 * 
 * <p>
 * OSID Version: 2.0
