C++ Standard Type Library

#include <multiset>

template < class Key,
class Compare=less<Key>,
class Allocator=allocator<Key> > class multiset

Parameters
Key -The key data type.
Traits - Function to compare two element values, argument is optional(default, binary predicate less).
Allocator - Memory allocator/deallocator, optional.

Constructors

multiset( );

explicit multiset ( const Compare& comp );

explicit multiset ( const Compare& comp, const Allocator& aloc );

set( const multiset& src );

template<class InputIterator>
multiset ( InputIterator start, InputIterator end);

template<class InputIterator>
multiset ( InputIterator start,
           InputIterator end,
           const Compare& comp );

template<class InputIterator>
multiset ( InputIterator start,
           InputIterator end,
           const Compare& comp,
           const Allocator& aloc );

Parameters

  aloc  - Allocator class
  comp  - Comparison function used to order the elements, defaults is hash_compare.
  src   - Source multiset be copied
  start - First element in the range
  end   - Last element in the range

Methods

begin() Returns a random-access iterator to the first element in the container.

clear() Remove all elements.

count() Returns a count of elements with a matching parameter-specified key.

empty() Check if container is empty.

end() Returns a random-access iterator that points just beyond the end of the container.

equal_range() Returns an iterator that addresses the location succeeding the last element in a map.

erase() Removes an element or a range of elements from the specified positions.

find() Returns an iterator to the element with the specified key.

get_allocator() Returns the allocator object.

insert() Inserts element or a number of elements at the specified position.

key_comp() Get a copy of the comparison object for ordering keys.

lower_bound() Get iterator to the first element with a key value that is equal to or greater than the specified key.

max_size() Get the maximum length.

rbegin() Get reverse iterator to the first element.

rend() Get reverse iterator to the end element.

size() Get the count of elements.

swap() Swap elements between two vectors.

upper_bound() Get iterator to the first element with a key value that is greater than the specified key.

value_comp() Get a copy of the comparison object.
