+.SH DESCRIPTION
+The QCacheIterator class provides an iterator for QCache collections.
+.PP
+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.
+.PP
+Multiple iterators are completely independent, even when they operate on the same QCache. QCache updates all iterators that refer an item when that item is removed.
+.PP
+QCacheIterator provides an operator++(), and an operator+=() to traverse the cache. The current() and currentKey() functions are used to access the current cache item and its key. The atFirst() and atLast() return TRUE if the iterator points to the first or last item in the cache respectively. The isEmpty() function returns TRUE if the cache is empty, and count() returns the number of items in the cache.
+.PP
+Note that atFirst() and atLast() refer to the iterator's arbitrary ordering, not to the cache's internal least recently used list.
+.PP
+See also QCache, Collection Classes, and Non-GUI Classes.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QCacheIterator::QCacheIterator ( const QCache<type> & cache )"
+Constructs an iterator for \fIcache\fR. The current iterator item is set to point to the first item in the \fIcache\fR.
+.SH "QCacheIterator::QCacheIterator ( const QCacheIterator<type> & ci )"
+Constructs an iterator for the same cache as \fIci\fR. The new iterator starts at the same item as ci.current(), but moves independently from there on.
+.SH "bool QCacheIterator::atFirst () const"
+Returns TRUE if the iterator points to the first item in the cache; otherwise returns FALSE. Note that this refers to the iterator's arbitrary ordering, not to the cache's internal least recently used list.
+.PP
+See also toFirst() and atLast().
+.SH "bool QCacheIterator::atLast () const"
+Returns TRUE if the iterator points to the last item in the cache; otherwise returns FALSE. Note that this refers to the iterator's arbitrary ordering, not to the cache's internal least recently used list.
+.PP
+See also toLast() and atFirst().
+.SH "uint QCacheIterator::count () const"
+Returns the number of items in the cache on which this iterator operates.
+.PP
+See also isEmpty().
+.SH "type * QCacheIterator::current () const"
+Returns a pointer to the current iterator item.
+.SH "QString QCacheIterator::currentKey () const"
+Returns the key for the current iterator item.
+.SH "bool QCacheIterator::isEmpty () const"
+Returns TRUE if the cache is empty, i.e. count() == 0; otherwise it returns FALSE.
+.PP
+See also count().
+.SH "QCacheIterator::operator type * () const"
+Cast operator. Returns a pointer to the current iterator item. Same as current().
+.SH "type * QCacheIterator::operator() ()"
+Makes the succeeding item current and returns the original current item.
+.PP
+If the current iterator item was the last item in the cache or if it was 0, 0 is returned.
+.SH "type * QCacheIterator::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.
+.SH "type * QCacheIterator::operator+= ( uint jump )"
+Returns the item \fIjump\fR positions after the current item, or 0 if it is beyond the last item. Makes this the current item.
+.SH "type * QCacheIterator::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.
+.SH "type * QCacheIterator::operator-= ( uint jump )"
+Returns the item \fIjump\fR positions before the current item, or 0 if it is before the first item. Makes this the current item.
+.SH "QCacheIterator<type> & QCacheIterator::operator= ( const QCacheIterator<type> & ci )"
+Makes this an iterator for the same cache as \fIci\fR. The new iterator starts at the same item as ci.current(), but moves independently thereafter.
+.SH "type * QCacheIterator::toFirst ()"
+Sets the iterator to point to the first item in the cache and returns a pointer to the item.
+.PP
+Sets the iterator to 0 and returns 0 if the cache is empty.
+.PP
+See also toLast() and isEmpty().
+.SH "type * QCacheIterator::toLast ()"
+Sets the iterator to point to the last item in the cache and returns a pointer to the item.
+.PP
+Sets the iterator to 0 and returns 0 if the cache is empty.
+.PP
+See also toFirst() and isEmpty().
