Two objects of concurrent_unordered_multiset are equal if the following conditions are true:
- They contain an equal number of elements.
- Each group of elements with the same key in one container has the corresponding group of equivalent elements in the other container (not necessarily in the same order).
template <typename T, typename Hash,
typename KeyEqual, typename Allocator>
bool operator==( const concurrent_unordered_multiset<T, Hash, KeyEqual, Allocator>& lhs,
const concurrent_unordered_multiset<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_multiset<T, Hash, KeyEqual, Allocator>& lhs,
const concurrent_unordered_multiset<T, Hash, KeyEqual, Allocator>& rhs );Equivalent to !(lhs == rhs).
Returns: true if lhs is not equal to rhs, false otherwise.
