multiset::const_reverse_iterator
typedef reverse_iterator<const_iterator>
const_reverse_iterator;
The type describes an object that can serve as a constant reverse bidirectional iterator for the
controlled sequence.
multiset::count
size_type count(const Key& keyval) const;
The member function returns the number of elements in the range
[lower_bound(keyval), upper_bound(keyval)).
multiset::difference_type
typedef T3 difference_type;
The signed integer type describes an object that can represent the difference between the
addresses of any two elements in the controlled sequence. It is described here as a synonym for
the implementation-defined type T3.
multiset::empty
bool empty() const;
The member function returns true for an empty controlled sequence.
multiset::end
iterator end();
const_iterator end() const;
The member function returns a bidirectional iterator that points just beyond the end of the
sequence.
multiset::equal_range
pair<iterator, iterator>
equal_range(const Key& keyval);
pair<const_iterator, const_iterator>
equal_range(const Key& keyval) const;
The member function returns a pair of iterators X such that X.first ==
lower_bound(keyval) and X.second == upper_bound(keyval).
