#include <rw/tvmset.h> template <class T, class C, class A=std::allocator<T> > class RWTValMultiSetConstIterator
RWTValMultiSetConstIterator provides a const iterator for RWTValMultiSet. A const iterator prohibits any changes to the collection over which it iterates.
The order of iteration over an RWTValMultiSet is dependent on the supplied 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 C++ Standard Library.
None
RWTValMultiSetConstIterator<T,C,A>(RWTValMultiSet<T,C>& h);
Creates an iterator for the multi-set h. The iterator begins in an undefined state and must be advanced before the first element is accessible.
bool operator()();
Advances self to the next element. If the iterator has advanced past the last element in the collection, false is returned. Otherwise, true is returned.
bool operator++();
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 references an undefined value and false is returned. Otherwise, true is returned. Note: no postincrement operator is provided.
const RWTValMultiSet<T,C,A>* container() const;
Returns a pointer to the collection being iterated over.
const T& key();
Returns the value pointed to by self.
void reset(); void reset(RWTValMultiSet<T,C,A>& h);
Resets the iterator so that after being advanced it points to the first element of the collection. Using reset() with no argument resets the iterator on the current container. Supplying a RWTValMultiSet to reset() resets the iterator on that container.
