template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<std::pair<const _Key, _Tp> >>class std::multimap< _Key, _Tp, _Compare, _Alloc >¶

A standard container made up of (key,value) pairs, which can be retrieved based on a key, in logarithmic time.

Template Parameters:

Meets the requirements of a container, a reversible container, and an associative container (using equivalent keys). For a multimap<Key,T> the key_type is Key, the mapped_type is T, and the value_type is std::pair<const Key,T>.

Multimaps support bidirectional iterators.

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

Build and insert a std::pair into the multimap.

Parameters:

Returns:

This function builds and inserts a (key, value) pair into the multimap. Contrary to a std::map the multimap does not rely on unique keys and thus multiple pairs with the same key can be inserted.

Insertion requires logarithmic time.

Definition at line 454 of file stl_multimap.h.

template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<std::pair<const _Key, _Tp> >> template<typename... _Args> iterator std::multimap< _Key, _Tp, _Compare, _Alloc >::emplace_hint (const_iterator__pos, _Args &&...__args) [inline]¶

Builds and inserts a std::pair into the multimap.

Parameters:

Returns:

This function inserts a (key, value) pair into the multimap. Contrary to a std::map the multimap does not rely on unique keys and thus multiple pairs with the same key 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.

For more on hinting, see: http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt07ch17.html

Insertion requires logarithmic time (if the hint is not taken).

Parameters:

Erases an element from a multimap.

Parameters:

Returns:

This function erases an element, pointed to by the given iterator, from a multimap. Note that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Erases elements according to the provided key.

Parameters:

Returns:

This function erases all elements located by the given key from a multimap. Note that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Erases a [first,last) range of elements from a multimap.

Parameters:

Returns:

This function erases a sequence of elements from a multimap. Note that this function only erases the elements, and that if the elements themselves are pointers, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Finds the beginning of a subsequence matching given key.

Multimap assignment operator. The dtor only erases the elements, and note that if the elements themselves are pointers, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Parameters:

All the elements of __x are copied, but unlike the copy constructor, the allocator object is not copied.

Multimap list assignment operator.

Parameters:

This function fills a multimap with copies of the elements in the initializer list __l.

Swaps data with another multimap.

Parameters:

This exchanges the elements between two multimaps 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.)

template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<std::pair<const _Key, _Tp> >> value_compare std::multimap< _Key, _Tp, _Compare, _Alloc >::value_comp () const [inline]¶

Returns a value comparison object, built from the key comparison object out of which the multimap was constructed.

template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<std::pair<const _Key, _Tp> >> std::multimap< _Key, _Tp, _Compare, _Alloc >::iterator¶

Inserts a std::pair into the multimap.

Parameters:

Returns:

This function inserts a (key, value) pair into the multimap. Contrary to a std::map the multimap does not rely on unique keys and thus multiple pairs with the same key 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.

For more on hinting, see: http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt07ch17.html

Insertion requires logarithmic time (if the hint is not taken).
