You might want to make certain that the clever pointer are not able to inadvertently be reset or reassigned from throughout the phone tree beneath.
That way you'll be able to’t alter the worth by mistake. That way might offer you the compiler optimization options.
Some policies goal to increase several kinds of protection while others aim to lessen the likelihood of incidents, several do both equally.

How granular should namespaces be? All lessons/functions meant to perform jointly and released with each other (as described in Sutter/Alexandrescu) or something narrower or wider?
Speaking of lambdas, what would weigh in on the choice involving lambdas and (community?) courses in algorithm calls and other callback situations?
We're in a tough-serious-time method and we don’t have applications that promise us that an exception is handled in the needed time.
In rarer cases, for instance policy classes, The category is employed to be a foundation class for advantage, not for polymorphic behavior. It is suggested to make Those people destructors shielded and nonvirtual:
Specifically, we’d truly like to have many of our policies backed up with measurements or much better illustrations.
A reliable and complete click here for more technique for managing errors and resource leaks is tough to retrofit into a technique.
Because C++eleven, static neighborhood variables are now initialized in a very thread-Protected way. When coupled with the RAII sample, static regional variables can substitute the need for crafting your own private double-checked locking for initialization.
If that's the case, it is probably going that those sources require watchful duplication, after which you try here must listen to the way objects are copied and assigned, or disable copying entirely.
