virtual bool is_equal(const std::pmr::memory_resource& other) const = 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.
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.
