Public Member Operators
T*
operator()();
Advances self to the next element, dereferences the resulting iterator and returns its
value. If the iterator has advanced past the last item in the container, the element returned
will be a nil pointer equivalent to boolean false.
RWBoolean
operator++();
Advances self to the next element. If the iterator has been reset or just created self will
now reference the first element. If, before iteration, self referenced the last association in
the set, self will now reference an undefined value and a value equivalent to false will be
returned. Otherwise, a value equivalent to true is returned. Note: no post-increment
operator is provided.
Public Member Functions
RWTPtrSet<T,C>*
container() const;
Returns a pointer to the collection being iterated over.
T*
key() const;
Returns the stored value pointed to by self. Undefined if self is not referencing a value
within the set.
void
reset();
void
reset(RWTPtrSet<T,C>& h);
Resets the iterator so that after being advanced it will point to the first element of the
collection. Using reset() with no argument will reset the iterator on the current container.
Supplying a RWTPtrSet to reset() will reset the iterator on the new container.
