The Bridge Pattern

by Rainer Grimm

In C++, a simplified version of the Bridge Pattern is often used. ... The key idea of the Pimpl Idiom is that the implementation of the class is hidden behind a pointer. Here is a recipe for implementing the Pimpl Idiom: ...

The power of ref-qualifiers

by Andreas Fertig

... What I have illustrated is that there is an issue with range-based for-loops. In (1), we call GetKeeper().items() in the head of the range-based for-loop. By doing this, we create a dangling reference.

ref-qualifiers to the rescue

Now, this brings us to ref-qualifiers. They are often associated with move semantics, but we can use them without move. However, we will soon see why ref-qualifiers make the most sense with move semantics.

A version of Keeper with ref-qualifiers looks like Listing 2...

Forgetting to take a lock when updating variables is a common mistake. One way to make the mistake harder to make is to force the access to occur through some mechanism that proves that you possess the lock. Maybe something like this: ...

Highlighting the student and support tickets for Meeting C++ 2022

by Jens Weller

With the schedule published, I'd like to highlight the student and support tickets for Meeting C++ 2022.

For a few years now Meeting C++ has hosted programs to give students, underrepresented folks and those who can't afford a ticket access to the conference. This is supported through the ticket sales and some times sponsorships.
