std::map<Key,T,Compare,Allocator>::at: std::map<Key,T,Compare,Allocator>::at
Command to display std::map<Key,T,Compare,Allocator>::at manual in Linux: $ man 3 std::map<Key,T,Compare,Allocator>::at
NAME
std::map<Key,T,Compare,Allocator>::at - std::map<Key,T,Compare,Allocator>::at
Synopsis
T& at( const Key& key ); (1) (since C++11)
const T& at( const Key& key ) const; (2) (since C++11)
Returns a reference to the mapped value of the element with key equivalent to key. If no such element exists, an exception of type std::out_of_range is thrown.
Parameters
key - the key of the element to find
Return value
Reference to the mapped value of the requested element
Exceptions
std::out_of_range if the container does not have an element with the specified key
Complexity
Logarithmic in the size of the container.
See also
access or insert specified element
operator[] (public member function)
