hash_map Members

Reference

Constructors

Constructs a hash_map that is empty or that is a copy of all or part of some other hash_map.

Typedefs

allocator_type	A type that represents the allocator class for the hash_map object.
const_iterator	A type that provides a bidirectional iterator that can read a const element in the hash_map.
const_pointer	A type that provides a pointer to a const element in a hash_map.
const_reference	A type that provides a reference to a const element stored in a hash_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 hash_map.
difference_type	A signed integer type that can be used to represent the number of elements of a hash_map in a range between elements pointed to by iterators.
iterator	A type that provides a bidirectional iterator that can read or modify any element in a hash_map.
key_compare	A type that provides a function object that can compare two sort keys to determine the relative order of two elements in the hash_map.
key_type	A type describes the sort key object that constitutes each element of the hash_map.
mapped_type	A type that represents the data type stored in a hash_map.
pointer	A type that provides a pointer to an element in a hash_map.
reference	A type that provides a reference to an element stored in a hash_map.
reverse_iterator	A type that provides a bidirectional iterator that can read or modify an element in a reversed hash_map.
size_type	An unsigned integer type that can represent the number of elements in a hash_map.
value_type	A type that provides a function object that can compare two elements as sort keys to determine their relative order in the hash_map.

Member Functions

begin	Returns an iterator addressing the first element in the hash_map.
clear	Erases all the elements of a hash_map.
count	Returns the number of elements in a hash_map whose key matches a parameter-specified key.
empty	Tests if a hash_map is empty.
end	Returns an iterator that addresses the location succeeding the last element in a hash_map.
equal_range	Returns a pair of iterators, respectively, to the first element in a hash_map with a key that is greater than a specified key and to the first element in the hash_map with a key that is equal to or greater than the key.
erase	Removes an element or a range of elements in a hash_map from specified positions
find	Returns an iterator addressing the location of an element in a hash_map that has a key equivalent to a specified key.
get_allocator	Returns a copy of the allocator object used to construct the hash_map.
insert	Inserts an element or a range of elements into a hash_map.
key_comp	Returns an iterator to the first element in a hash_map with a key value that is equal to or greater than that of a specified key.
lower_bound	Returns an iterator to the first element in a hash_map with a key value that is equal to or greater than that of a specified key.
max_size	Returns the maximum length of the hash_map.
rbegin	Returns an iterator addressing the first element in a reversed hash_map.
rend	Returns an iterator that addresses the location succeeding the last element in a reversed hash_map.
size	Returns the number of elements in the hash_map.
swap	Exchanges the elements of two hash_maps.
upper_bound	Returns an iterator to the first element in a hash_map that with a key value that is greater than that of a specified key.
value_comp	Retrieves a copy of the comparison object used to order element values in a hash_map.

Operators
