template metaprogramming(模板元编程)是编写template-based c++程序并执行于编译期的过程。是以c++写成,执行于c++编译器内的程序。一旦tmp程序执行结束,其输出,也就是template具现出来的若干c++源码,便会一如往常的编译。 tmp有两个伟大的效力。第一,它让某些事情更容易。如果没有它,那些事情将是困难的,甚至是不可能...
I have been developping a lot in C++, much on and with templates, and some metaprogramming. The book goes through the features, tricks, and pitfalls of C++ templates, with many explanations., and then demonstrates some programming patterns. Much can readily be found in reference documentation,...

Template Metaprogramming in C++CS242, Fall 2009 Keith SchwarzA is a type or function parameterized over a set of types, functions, or constants.template struct Pair { One first; Two second; };struct Pair { One first; Two second; };template struct Pair {first; second;};Providing ...
如何深入浅出通俗易懂地介绍一下c++ 里的Template metaprogramming?最近准备参加一个workshop,会前问卷调查了解与会者对各类语言的熟悉程度。对每一种语言,从不懂到精通选择最符合自己的描述。对于c++,最高阶(精通…显示全部 关注者369 被浏览81,035 关注问题写回答 邀请回答 好问题 4 3 条...
2023/02/28 ztC++20, concept, template metaprogramming发表评论 之前我们已经反复地提到过 C++ template 需要一种强制规范化策略,就跟运行时多态是通过 virtual function 定义来保证其接口的一致性一样,如何把不同类型公用的接口通过一种方式交给编译器,从而让编译器在编译时可以依据这些接口的定义给出更为准确的错...
上述值计算的元编程方式称为值元编程(value metaprogramming),此外模板元编程还能产生类型,即类型元编程(type metaprogramming),能产生类型的元函数称为类型元函数,比如: // 基本模板 template<typename T> struct RemoveAllExtentsT { using Type = T; }; // 局部特化 template<typename T, std::size_t SZ> ...
An excellent introduction to template metaprogramming can be found in Chapter 10 of Czarnecki s and Eisenecker s book on generative programming [4]. Another thing I need to address (once again) before I can get to the point of this column is the subject of Microsoft s support of C++ ...
