NAME¶

std::pmr::memory_resource::do_is_equal - std::pmr::memory_resource::do_is_equal

Synopsis¶

virtual bool do_is_equal( const std::pmr::memory_resource& other ) (since C++17)
const noexcept = 0;

Compares *this for equality with other.

Two memory_resources compare equal if and only if memory allocated from one
memory_resource can be deallocated from the other and vice versa.

Notes¶

The most-derived type of other may not match the most derived type of *this. A
derived class implementation therefore must typically check whether the most derived
types of *this and other match using dynamic_cast, and immediately return false if
the cast fails.
