Detailed Description

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>>
class std::multiset< _Key, _Compare, _Alloc >

A standard container made up of elements, which can be retrieved in logarithmic time.

Template Parameters
_KeyType of key objects.
_CompareComparison function object type, defaults to less<_Key>.
_AllocAllocator type, defaults to allocator<_Key>.

Meets the requirements of a container, a reversible container, and an associative container (using equivalent keys). For a multiset<Key> the key_type and value_type are Key.

Multisets support bidirectional iterators.

The private tree data is declared exactly the same way for set and multiset; the distinction is made entirely in how the tree functions are called (*_unique versus *_equal, same as the standard).

template<typename... _Args>
iterator std::multiset< _Key, _Compare, _Alloc >::emplace ( _Args &&...  __args)
inline

Builds and inserts an element into the multiset.

Parameters
__argsArguments used to generate the element instance to be inserted.
Returns
An iterator that points to the inserted element.

This function inserts an element into the multiset. Contrary to a std::set the multiset does not rely on unique keys and thus multiple copies of the same element can be inserted.

Insertion requires logarithmic time.

template<typename... _Args>
iterator std::multiset< _Key, _Compare, _Alloc >::emplace_hint ( const_iterator  __pos,
_Args &&...  __args

inline

Builds and inserts an element into the multiset.

Parameters
__posAn iterator that serves as a hint as to where the element should be inserted.
__argsArguments used to generate the element instance to be inserted.
Returns
An iterator that points to the inserted element.

This function inserts an element into the multiset. Contrary to a std::set the multiset does not rely on unique keys and thus multiple copies of the same element can be inserted.

Note that the first parameter is only a hint and can potentially improve the performance of the insertion process. A bad hint would cause no gains in efficiency.

See http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt07ch17.html for more on hinting.

std::pair<iterator, iterator> std::multiset< _Key, _Compare, _Alloc >::equal_range ( const key_type &  __x)
inline

Finds a subsequence matching given key.

Parameters
__xKey to be located.
Returns
Pair of iterators that possibly points to the subsequence matching given key.

This function is equivalent to

* std::make_pair(c.lower_bound(val),
* c.upper_bound(val))
*

(but is faster than making the calls separately).

This function probably only makes sense for multisets.

Parameters
__xKey of element to be erased.
Returns

iterator std::multiset< _Key, _Compare, _Alloc >::upper_bound ( const key_type &  __x)
inline

Finds the end of a subsequence matching given key.

Parameters
__xKey to be located.
Returns
Iterator pointing to the first element greater than key, or end().

Member Data Documentation

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>>
std::multiset< _Key, _Compare, _Alloc >::void

Swaps data with another multiset.

Parameters
__xA multiset of the same element and allocator types.

This exchanges the elements between two multisets in constant time. (It is only swapping a pointer, an integer, and an instance of the Compare type (which itself is often stateless and empty), so it should be quite fast.) Note that the global std::swap() function is specialized such that std::swap(s1,s2) will feed to this function.
