Replace naked
newcalls to create object instances in the heap that are then used to createstd::unique_ptr&std::shared_ptrinstances.why
Simplifies code and follows C++ Core Guidelines, see R.22: Use make_shared() to make shared_ptrs & R.23: Use make_unique() to make unique_ptrs
Additionally, the use of
std::make_sharedallows for an optimization by which the shared pointer's control block and the object can be allocated in the same memory block, which increasees memory locality (and thus performance).
