Detailed Description

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.

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).

Erases an element from a multimap. Parameters:

position An iterator pointing to the element to be erased.

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:

x Key of element to be erased.

Returns:

The number of elements erased.

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:

first Iterator pointing to the start of the range to be erased.
last Iterator pointing to the end of the range to be erased.

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.

Tries to locate an element in a multimap. Parameters:

x Key of (key, value) pair to be located.

Returns:

Read-only (constant) iterator pointing to sought-after element, or end() if not found.

This function takes a key and tries to locate the element with which the key matches. If successful the function returns a constant iterator pointing to the sought after pair. If unsuccessful it returns the past-the-end ( end() ) iterator.

Tries to locate an element in a multimap. Parameters:

x Key of (key, value) pair to be located.

Returns:

Iterator pointing to sought-after element, or end() if not found.

This function takes a key and tries to locate the element with which the key matches. If successful the function returns an iterator pointing to the sought after pair. If unsuccessful it returns the past-the-end ( end() ) iterator.

Inserts a std::pair into the multimap. Parameters:

x Pair to be inserted (see std::make_pair for easy creation of pairs).

Returns:

An iterator that points to the inserted (key,value) pair.

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.

Insertion requires logarithmic time.

Definition at line 437 of file stl_multimap.h.

template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<std::pair<const _Key, _Tp> >> iterator std::multimap< _Key, _Tp, _Compare, _Alloc >::insert (iterator __position, const value_type & __x) [inline]

Inserts a std::pair into the multimap. Parameters:

position An iterator that serves as a hint as to where the pair should be inserted.
x Pair to be inserted (see std::make_pair for easy creation of pairs).

Returns:

An iterator that points to the inserted (key,value) pair.

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).

A template function that attempts to insert a range of elements. Parameters:

first Iterator pointing to the start of the range to be inserted.
last Iterator pointing to the end of the range.

Complexity similar to that of the range constructor.

x Key of (key, value) pair to be located.

Returns:

Read-only (constant) iterator pointing to first element equal to or greater than key, or end().

Returns:

Iterator pointing to first element equal to or greater than key, or end().

This function returns the first element of a subsequence of elements that matches the given key. If unsuccessful it returns an iterator pointing to the first element that has a greater value than given key or end() if no such element exists.

Multimap move assignment operator. Parameters:

x A multimap of identical element and allocator types.

The contents of x are moved into this multimap (without copying). x is a valid, but unspecified multimap.

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:

x A multimap of identical element and allocator types.

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

Multimap list assignment operator. Parameters:

l An initializer_list.

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

Note that the assignment completely changes the multimap and that the resulting multimap's size is the same as the number of elements assigned. Old data may be lost.

Swaps data with another multimap. Parameters:

x A multimap of the same element and allocator types.

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.)

Returns:

Iterator pointing to the first element greater than key, or end().
