Non-member binary comparisons#

Two objects of concurrent_hash_map are equal if the following conditions are true:

  • They contain equal number of elements.

  • Each element from one container is also available in the other.

template <typename Key, typename T, typename HashCompare, typename Allocator>
bool operator==( const concurrent_hash_map<Key, T, HashCompare, Allocator>& lhs,
                 const concurrent_hash_map<Key, T, HashCompare, Allocator>& rhs );

Returns: true if lhs is equivalent to rhs; false, otherwise.


template <typename Key, typename T, typename HashCompare, typename Allocator>
bool operator!=( const concurrent_hash_map<Key, T, HashCompare, Allocator>& lhs,
                 const concurrent_hash_map<Key, T, HashCompare, Allocator>& rhs );

Equivalent to !(lhs == rhs).

Returns: true if lhs is not equal to rhs; false, otherwise.
