DESCRIPTION

       The QIntCacheIterator class provides an iterator for
       QIntCache collections.

       Note that the traversal order is arbitrary, you are not
       guaranteed any particular order. If new objects are
       inserted into the cache while the iterator is active, the
       iterator may or may not see them.

       Multiple iterators are completely independent, even when
       they operate on the same QIntCache. QIntCache updates all
       iterators that refer an item when that item is removed.

       QIntCacheIterator provides an operator++(), and an
       operator+=() to traverse the cache, current() and
       currentKey() to access the current cache item and its key,
       atFirst() atLast() which return TRUE if the iterator
       points to the first/last item in the cache, isEmpty()
       which returns TRUE if the cache is empty and finally
       count() which returns the number of items in the cache.

       Note that atFirst() and atLast() refer to the iterator's
       arbitrary ordering, not to the cache's internal LRU list.

       See also QIntCache.


QIntCacheIterator::QIntCacheIterator ( const QIntCache &

       cache )
       Constructs an iterator for cache. The current iterator
       item is set to point on the first item in the cache (or
       rather, the first item is defined to be the item at which
       this constructor sets the iterator to point).


QIntCacheIterator::QIntCacheIterator ( const

       QIntCacheIterator<type> & ci )
       Constructs an iterator for the same cache as ci. The new
       iterator starts at the same item as ci.current(), but
       moves independently from there on.


QIntCacheIterator::operator type * () const

       Cast operator. Returns a pointer to the current iterator
       item. Same as current().


bool QIntCacheIterator::atFirst () const

       Returns TRUE if the iterator points to the first item in
       the cache. Note that this refers to the iterator's
       arbitrary ordering, not to the cache's internal LRU list.

       See also toFirst() and atLast().


bool QIntCacheIterator::atLast () const

       Returns TRUE if the iterator points to the last item in
       the cache. Note that this refers to the iterator's
       arbitrary ordering, not to the cache's internal LRU list.

       See also toLast() and atFirst().


uint QIntCacheIterator::count () const

       Returns the number of items in the cache on which this
       iterator operates.

       See also isEmpty().


type * QIntCacheIterator::current () const

       Returns a pointer to the current iterator item.


long QIntCacheIterator::currentKey () const

       Returns the key for the current iterator item.


bool QIntCacheIterator::isEmpty () const

       Returns TRUE if the cache is empty, i.e. count() == 0,
       otherwise FALSE.

       See also count().


type * QIntCacheIterator::operator() ()

       Makes the succeeding item current and returns the original
       current item.

       cache or if it was null, null is returned.


type * QIntCacheIterator::operator++ ()

       Prefix ++ makes the iterator point to the item just after
       current(), and makes that the new current item for the
       iterator. If current() was the last item, operator--()
       returns 0.


type * QIntCacheIterator::operator+= ( uint jump )

       Returns the item jump positions after the current item, or
       null if it is beyond the last item. Makes this the current
       item.


type * QIntCacheIterator::operator-- ()

       Prefix -- makes the iterator point to the item just before
       current(), and makes that the new current item for the
       iterator. If current() was the first item, operator--()
       returns 0.


type * QIntCacheIterator::operator-= ( uint jump )

       Returns the item jump positions before the current item,
       or null if it is beyond the first item. Makes this the
       current item.


QIntCacheIterator& QIntCacheIterator::operator= ( const

       QIntCacheIterator<type> & ci )
       Makes this an iterator for the same cache as ci. The new
       iterator starts at the same item as ci.current(), but
       moves independently thereafter.


type * QIntCacheIterator::toFirst ()

       Sets the iterator to point to the first item in the cache
       and returns a pointer to the item.

       Sets the iterator to null and returns null if if the cache
       is empty.

       See also toLast() and isEmpty().


type * QIntCacheIterator::toLast ()

       Sets the iterator to point to the last item in the cache
       and returns a pointer to the item.

       Sets the iterator to null and returns null if if the cache
       is empty.

       See also  toFirst() and isEmpty().
