abstract class TPrimitiveIterator
extends TIterator

Implements all iterator functions for the hashed object set. Subclasses may override objectAtIndex to vary the object returned by calls to next() (e.g. for values, and Map.Entry objects).

Note that iteration is fastest if you forego the calls to hasNext in favor of checking the size of the structure yourself and then call next() that many times:

 Iterator i = collection.iterator();
 for (int size = collection.size(); size-- > 0;) {
   Object o = i.next();
 }
 

You may, of course, use the hasNext(), next() idiom too if you aren't in a performance critical spot.
