template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<std::pair<const _Key, _Tp> >>
class std::map< _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 unique keys). For a map<Key,T> the key_type is Key, the mapped_type is T, and the value_type is std::pair<const Key,T>.
Maps 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).

template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<std::pair<const _Key, _Tp> >>
Attempts to insert a std::pair into the map.
- Parameters
-
- Returns
- A pair, of which the first element is an iterator that points to the possibly inserted pair, and the second is a bool that is true if the pair was actually inserted.
This function attempts to insert a (key, value) pair into the map. A map relies on unique keys and thus a pair is only inserted if its first element (the key) is not already present in the map.
Insertion requires logarithmic time.

inline |
Attempts to insert a std::pair into the map.
- 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 element with key of x (may or may not be the pair passed in).
This function is not concerned about whether the insertion took place, and thus does not return a boolean like the single-argument insert() does. 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.
Insertion requires logarithmic time (if the hint is not taken).

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

Returns a read/write reverse iterator that points to the last pair in the map. Iteration is done in descending order according to the keys.

template<typename _Key, typename _Tp, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<std::pair<const _Key, _Tp> >>
Returns a read-only (constant) reverse iterator that points to the last pair in the map. Iteration is done in descending order according to the keys.

Swaps data with another map.
- Parameters
-
| x | A map of the same element and allocator types. |
This exchanges the elements between two maps 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(m1,m2) will feed to this function.
