=============================
Non-member binary comparisons
=============================

Two ``oneapi::tbb::concurrent_map`` objects are equal if they have the same number of elements
and each element in one container is equal to the element in other container on the same position.

.. code:: cpp

    template <typename Key, typename T, typename Compare, typename Allocator>
    bool operator==( const concurrent_map<Key, T, Compare, Allocator>& lhs,
                     const concurrent_map<Key, T, Compare, Allocator>& rhs )

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

-----------------------------------------------------

.. code:: cpp

    template <typename Key, typename T, typename Compare, typename Allocator>
    bool operator!=( const concurrent_map<Key, T, Compare, Allocator>& lhs,
                     const concurrent_map<Key, T, Compare, Allocator>& rhs )

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