Reference

Constructors

map	Constructs a list of a specific size or with elements of a specific value or with a specific allocator or as a copy of some other map.

Typedefs

allocator_type	A typedef for the allocator class for the map object.
const_iterator	A typedef for a bidirectional iterator that can read a const element in the map.
const_pointer	A typedef for a pointer to a const element in a map.
const_reference	A typedef for a reference to a const element stored in a map for reading and performing const operations.
const_reverse_iterator	A type that provides a bidirectional iterator that can read any const element in the map.
difference_type	A signed integer typedef for the number of elements of a map in a range between elements pointed to by iterators.
iterator	A typedef for a bidirectional iterator that can read or modify any element in a map.
key_compare	A typedef for a function object that can compare two sort keys to determine the relative order of two elements in the map.
key_type	A typedef for the sort key stored in each element of the map.
mapped_type	A typedef for the data stored in each element of a map.
pointer	A typedef for a pointer to a const element in a map.
reference	A typedef for a reference to an element stored in a map.
reverse_iterator	A typedef for a bidirectional iterator that can read or modify an element in a reversed map.
size_type	An unsigned integer typedef for the number of elements in a map
value_type	A typedef for the type of object stored as an element in a map.

Methods

map::at	Finds an element with a specified key value.
begin	Returns an iterator that points to the first element in the map.
map::cbegin	Returns a const iterator that points to the first element in the map.
map::cend	Returns a const past-the-end iterator.
clear	Erases all the elements of a map.
count	Returns the number of elements in a map whose key matches the key specified in a parameter.
map::crbegin	Returns a const iterator that points to the first element in a reversed map.
map::crend	Returns a const iterator that points to the location after the last element in a reversed map.
map::emplace	Inserts an element constructed in place into the map.
map::emplace_hint	Inserts an element constructed in place into the map, with a placement hint.
empty	Returns true if a map is empty.
end	Returns the past-the-end iterator.
equal_range	Returns a pair of iterators. The first iterator in the pair points to the first element in a map with a key that is greater than a specified key. The second iterator in the pair points to the first element in the map with a key that is equal to or greater than the key.
erase	Removes an element or a range of elements in a map from the specified positions.
find	Returns an iterator that points to the location of an element in a map that has a key equal to a specified key.
get_allocator	Returns a copy of the allocator object that is used to construct the map.
insert	Inserts an element or a range of elements into the map at a specified position.
key_comp	Returns a copy of the comparison object that used to order keys in a map.
lower_bound	Returns an iterator to the first element in a map that has a key value that is equal to or greater than that of a specified key.
max_size	Returns the maximum length of the map.
rbegin	Returns an iterator that points to the first element in a reversed map.
rend	Returns an iterator that points to the location after the last element in a reversed map.
size	Returns the number of elements in the map.
swap	Exchanges the elements of two maps.
upper_bound	Returns an iterator to the first element in a map that has a key value that is greater than that of a specified key.
value_comp	Retrieves a copy of the comparison object that is used to order element values in a map.

Operators

operator[]	Inserts an element into a map with a specified key value.
map::operator=	Replaces the elements of a map with a copy of another map.
