Interface TPrimitiveIterator

All Superinterfaces:

TIterator

public interface 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.

Method Summary

boolean	hasNext() Returns true if the iterator can be advanced past its current location.
void	remove() Removes the last entry returned by the iterator.

Method Detail

hasNext

boolean hasNext()

Returns true if the iterator can be advanced past its current location.

Specified by:

hasNext in interface TIterator

Returns:

a boolean value

remove

void remove()

Removes the last entry returned by the iterator. Invoking this method more than once for a single entry will leave the underlying data structure in a confused state.
