One of two iterators for class RWOrdered. Traverses the collection from the first to the last item. As a const
iterator, this iterator does not change anything in the underlying data structure.
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Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it brings undefined results.
#include <rw/ordcltn.h> RWOrdered a; RWOrderedConstIterator iter(a);
None
RWOrderedConstIterator::RWOrderedConstIterator | ( | const RWOrdered & | ord | ) | [inline] |
Constructs an RWOrderedConstIterator from an RWOrdered collection. Immediately after construction the position of the iterator is undefined.
RWOrderedConstIterator::RWOrderedConstIterator | ( | const RWOrderedIterator & | it | ) | [inline] |
Constructs an RWOrderedConstIterator from an RWOrderedIterator. Immediately after construction the position of the iterator is undefined.
virtual const RWCollectable* RWOrderedConstIterator::findNext | ( | const RWCollectable * | target | ) | [virtual] |
Moves the iterator to the next item which isEqual() to the item pointed to by target and returns it. If no item is found, returns rwnil and the position of the iterator is undefined.
Implements RWConstIterator.
virtual const RWCollectable* RWOrderedConstIterator::key | ( | ) | const [virtual] |
Returns the item at the current iterator position.
Implements RWConstIterator.
virtual const RWCollectable* RWOrderedConstIterator::operator() | ( | ) | [virtual] |
Advances the iterator and returns the next item, or rwnil if the end of the collection has been reached.
Implements RWConstIterator.
virtual void RWOrderedConstIterator::reset | ( | ) | [inline, virtual] |
Resets the iterator to the state it had immediately after construction.
Implements RWConstIterator.
