Iterator for class RWBag, which allows sequential access to all the elements of RWBag. Note that because an RWBag is unordered, elements are not accessed in any particular order. If an item was inserted N
times into the collection, then it will be visited N
consecutive times.
Like 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Once the iterator has advanced beyond the end of the collection it is no longer valid, so continuing to use it has undefined results.
RWBagIterator::RWBagIterator | ( | const RWBag & | ) |
Construct an iterator for an RWBag. After construction, the position of the iterator is undefined.
|
virtual |
Moves the iterator to the next item that isEqual() to the object pointed to by target, and returns it. Hashing is used to find the target. If no item is found, returns rwnil and the position of the iterator is undefined.
Implements RWIterator.
|
virtual |
Returns the item at the current iterator position.
Implements RWIterator.
|
virtual |
Advances the iterator and returns the next item, or rwnil if the end of the collection has been reached.
Implements RWIterator.
|
virtual |
Resets the iterator to the state it had immediately after construction.
Implements RWIterator.
