std::pmr::memory_resource::do_is_equal
From cppreference.com
< cpp | memory | memory resource
virtual bool do_is_equal(const std::pmr::memory_resource& other) const noexcept = 0; |
(since C++17) | |
Compares *this
for equality with other
.
Two memory_resource
s 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.
