Examples of jade.util.leap.Iterator

jade.util.leap.Iterator
The LEAP (environment-dependent) version of the &qote;java.util.Iterator&qote; interface. This interface appears to be exactly the same in J2SE, PJAVA and MIDP. The internal implementation is different in the three cases however. @author Nicolas Lhuillier @version 1.0, 29/09/00 @see java.util.Iterator
