Scott Meyers in Oslo: Friday, June 14
On Friday, June 14, Scott Meyers will be giving a talk open to the public at the Oslo C++ Users Group.
From Scott's announcement:
Lambdas vs. std::bind in C++11 and C++14
Scott Meyers
C++ developers have long had a need to bind functions and arguments together for a later call. This is what makes it possible to invoke member functions on objects inside STL algorithms. The same technology can be used to create custom callback functions and to adapt function interfaces to different calling contexts.
In C++98, such binding was accomplished via
std::bind1standstd::bind2nd. TR1 addedstd::tr1::bind, which was promoted tostd::bindin C++11. But C++11 also introduced lambda expressions, and they’re slated to become even more powerful in C++14. That means that there are now two mechanisms in C++ for binding functions to arguments for later calls:std::bindand lambda expressions. In this talk, Scott examines the pros and cons of each approach, comparing them in terms of expressiveness, clarity, and efficiency, and he comes to the conclusion that one should almost always be used instead of the other. But which one?
This presentation assumes a basic familiarity with
std::bindand C++11 lambda expressions.
The C++Now 2013 conference is still in flight, but presentation materials are being made available online as the conference progresses. You can find them here in their GitHub repository:
As noted yesterday, the C++ Now 2013 conference has sold out well in advance. There's one other conference that sold out almost immediately we should also mention:
