Q3AsciiCacheIterator Class Reference

Q3AsciiCacheIterator::Q3AsciiCacheIterator ( const Q3AsciiCache<type> & cache )

Constructs an iterator for cache. The current iterator item is set to point to the first item in the cache.

Q3AsciiCacheIterator::Q3AsciiCacheIterator ( const Q3AsciiCacheIterator<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.

bool Q3AsciiCacheIterator::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.

See also toFirst() and atLast().

bool Q3AsciiCacheIterator::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.

See also toLast() and atFirst().

uint Q3AsciiCacheIterator::count () const

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

See also isEmpty().

type * Q3AsciiCacheIterator::current () const

Returns a pointer to the current iterator item.

const char * Q3AsciiCacheIterator::currentKey () const

Returns the key for the current iterator item.

bool Q3AsciiCacheIterator::isEmpty () const

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

See also count().

type * Q3AsciiCacheIterator::toFirst ()

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

Sets the iterator to 0 and returns 0 if the cache is empty.

See also toLast() and isEmpty().

type * Q3AsciiCacheIterator::toLast ()

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

Sets the iterator to 0 and returns 0 if the cache is empty.

See also toFirst() and isEmpty().

Q3AsciiCacheIterator::operator type * () const

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

type * Q3AsciiCacheIterator::operator() ()

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

If the current iterator item was the last item in the cache or if it was 0, 0 is returned.

type * Q3AsciiCacheIterator::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 * Q3AsciiCacheIterator::operator+= ( uint jump )

Returns the item jump positions after the current item, or 0 if it is beyond the last item. Makes this the current item.

type * Q3AsciiCacheIterator::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 * Q3AsciiCacheIterator::operator-= ( uint jump )

Returns the item jump positions before the current item, or 0 if it is before the first item. Makes this the current item.

Q3AsciiCacheIterator<type> & Q3AsciiCacheIterator::operator= ( const Q3AsciiCacheIterator<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.
