5 ways how unique_ptr enhances resource safety in your code

by Bartlomiej Filipek

From the article:

While shared_ptr and weak_ptr are more complex, unique_ptr seems to be a perfect replacement for owning raw pointers. Not to mention is the fact that this pointer type is mostly a compile time “wrapper” and it cost almost nothing in the runtime.

Your own type predicate--Andrzej Krzemieński

A very detailled and complete article to start playing with template predicates!

Your own type predicate

by Andrzej Krzemieński

From the article:

In this post we will see how to define a type trait or a type predicate or a meta-function that would allow us to check at compile time whether a type exposes an interface that we need. That is, we want to check if a given type T has:

• nested typename result_type,
• static member function set_limit that takes one argument of type int,
• member function get_result that returns type const result_type& and that is declared not to throw exceptions...

A new version is here!

CLion 2017.3 released with C++ support improvements, Valgrind Memcheck, Boost.Test and much more

by Anastasia Kazakova

From the article:

This year’s third release of CLion managed to accomplish both missions – bring dozens of C++ language support fixes, and overhaul and integrate new tools like Boost.Test and Valgrind Memcheck. Besides, v2017.3 updates a number of bundled tools, provides a simpler and more flexible way to configure toolchains, and improves the UI for running/debugging your applications...

Quick Q: May a destructor be final?

By Adrien Hamelin | Dec 1, 2017 02:00 PM | Tags: intermediate c++11

Quick A: Yes, as any other virtual member function.

Recently on SO:

May a destructor be final?

May a C++ destructor be declared as final?

Yes.

And if so, does that prevent declaration of a derived class:

Yes, because the derived class would have to declare a destructor (either explicitly by you or implicitly by the compiler), and that destructor would be overriding a function declared final, which is ill-formed.

The rule is [class.virtual]/4:

If a virtual function f in some class B is marked with the virt-specifier final and in a class D derived from B a function D​::​f overrides B​::​f, the program is ill-formed.

It's the derivation itself that is ill-formed, it doesn't have to be used.

Is declaring a destructor to be final a workable idiom for indicating that a class is not intended to be used as a base class?

Effectively, but you should just mark the class final. It's quite a bit more explicit.
