comparison operators

function

<map>

template <class Key, class T, class Compare, class Allocator>
  bool operator== ( const map<Key,T,Compare,Allocator>& x,
                    const map<Key,T,Compare,Allocator>& y );
template <class Key, class T, class Compare, class Allocator>
  bool operator<  ( const map<Key,T,Compare,Allocator>& x,

                    const map<Key,T,Compare,Allocator>& y );

  bool operator>= ( const map<Key,T,Compare,Allocator>& x,
                    const map<Key,T,Compare,Allocator>& y );
template <class Key, class T, class Compare, class Allocator>
  bool operator<= ( const map<Key,T,Compare,Allocator>& x,
                    const map<Key,T,Compare,Allocator>& y );

Global comparison operator functions

These overloaded global operator functions perform the appropriate comparison operation between map containers x and y.

Operations == and != are performed by comparing the elements using algorithm equal.

Operations <, >, <= and >= are performed by using algorithm lexicographical_compare, which requires that the type of the elements (T) has the < operation (less-than) defined between two objects of that type.

These operators are overloaded in header .

Parameters

x, y: map containers, having both the same template parameters (Key, T, Compare and Allocator).

Return Value

true if the condition holds, and false otherwise.
