Tools.h++ Class Reference

Public Constructors
RWTPtrHashMultiSetIterator<T,H,EQ>
(RWTPtrHashMultiSet<T,H,EQ>&h);
Creates an iterator for the hashed multi-set h. The iterator begins in an undefined state and
must be advanced before the first element will be accessible.
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
multiset, 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
RWTPtrHashMultiSet<T,H,EQ>*
container() const;
Returns a pointer to the collection being iterated over.
T*
key() const;
Returns the value currently referenced by self. Undefined if self is not referencing a value
within the multiset.
void
reset();
void
reset(RWTPtrHashMultiSet<T,H,EQ>& h);
Resets the iterator so that after being advanced it will reference the first element of the
collection. Using reset() with no argument will reset the iterator on the current container.
Supplying a RWTPtrHashMultiSet to reset() will reset the iterator on that container.
