class | RWHashTableConstIterator |
Iterator for class RWHashTable, which allows sequential access to all the elements of RWHashTable.
As with all Rogue Wave iterators, the "current item" is undefined immediately after construction – you must define it by using operator()() or some other (valid) operation.
Once the iterator has advanced beyond the end of the collection it is no longer valid – continuing to use it brings undefined results.
RWHashTableIterator::RWHashTableIterator | ( | RWHashTable & | h | ) |
Constructs an iterator for an RWHashTable. After construction, the position of the iterator is undefined.
|
virtual |
Moves the iterator to the next item which isEqual() to the item pointed to by target and returns it.
Implements RWIterator.
Reimplemented in RWHashDictionaryIterator.
|
virtual |
Returns the item at the current iterator position.
Implements RWIterator.
Reimplemented in RWHashDictionaryIterator.
|
virtual |
Advances the iterator and returns the next item, or rwnil if the end of the collection has been reached.
Implements RWIterator.
Reimplemented in RWHashDictionaryIterator.
RWCollectable * RWHashTableIterator::remove | ( | ) |
Removes the item at the current iterator position from the collection.
RWCollectable * RWHashTableIterator::removeNext | ( | const RWCollectable * | target | ) |
|
virtual |
Resets the iterator to the state it had immediately after construction.
Implements RWIterator.
Reimplemented in RWHashDictionaryIterator, and RWSetIterator.
