Non-member binary comparisons#

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

  • They contain an equal number of elements.

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

template <typename T, typename Hash,
          typename KeyEqual, typename Allocator>
bool operator==( const concurrent_unordered_set<T, Hash, KeyEqual, Allocator>& lhs,
                 const concurrent_unordered_set<T, Hash, KeyEqual, Allocator>& rhs );

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


template <typename T, typename Hash,
          typename KeyEqual, typename Allocator>
bool operator!=( const concurrent_unordered_set<T, Hash, KeyEqual, Allocator>& lhs,
                 const concurrent_unordered_set<T, Hash, KeyEqual, Allocator>& rhs );

Equivalent to !(lhs == rhs).

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