nz.ac.waikato.jdsl.core.api.ObjectIterator

Iterator over a set of objects. No order of the objects is required by this interface, although order may be promised or required by users of the interface. Conceptually, the iterator starts out positioned before the first object to be considered. With each call to next(), the iterator skips over another object and returns the object skipped over, until the iterator is positioned after the last object. Note that NoSuchElementException indicates two different failure states: when the iterator is positioned before the first object, object() fails; when the iterator is positioned after the last object, next() fails. @version JDSL 2.1.1 @author Mark Handy
