#include <rw/tpmset.h> template <class T, class C, class A=std::allocator<T*> > class RWTPtrMultiSetConstIterator
RWTPtrMultiSetConstIterator provides a const iterator interface to Standard Library-based RWTPtrMultiSet collections.
The order of iteration over an RWTPtrMultiSet is dependent upon the comparator object parameter C as applied to the values stored in the container.
The current item referenced by this iterator is undefined after construction or after a call to reset(). The iterator becomes valid after being advanced with either a preincrement or operator().
For both operator++ and operator(), iterating past the last element returns a value equivalent to boolean false. Continued increments return a value equivalent to false until reset() is called.
The value type must have operator== and operator< defined. This requirement is imposed by the Standard C++ Library.
RWTPtrMultiSetConstIterator<T,C,A>(const RWTPtrMultiSet<T,C,A>& m);
Creates an iterator for the multi-set m. The iterator begins in an undefined state and must be advanced before the first element is accessible
const 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 is a nil pointer equivalent to boolean false.
Advances self to the next element. If the iterator has been reset or just created self now references the first element. If, before iteration, self referenced the last association in the multi-set, self now points to an undefined value and a value equivalent to false is returned. Otherwise, a value equivalent to true is returned. Note: no post-increment operator is provided.
const RWTPtrMultiSet<T,C,A>* container() const;
Returns a pointer to the collection being iterated over.
const T* key();
Returns the stored value referenced by self. Undefined if self is not referencing a value within the list.
void reset(); void reset(RWTPtrMultiSet<T,C,A>& h);
Resets the iterator so that after being advanced it references the first element of the collection. Using reset() with no argument resets the iterator on the current container. Supplying a RWTPtrMultiSet with reset() resets the iterator on that container.
