NAME

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

Synopsis


virtual bool is_equal(const memory_resource& other) const noexcept = 0; (library fundamentals TS)


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.
