Although C++ is one of the most widespread programming languages, [1] many prominent software engineers criticize C++ (the language, and its compilers) arguing that it is overly complex [2] and fundamentally flawed. [3] Among the critics have been: Robert Pike, [2] Joshua Bloch, Linus Torvalds, [3] Donald Knuth, Richard Stallman, and Ken Thompson.
The curiously recurring template pattern (CRTP) is an idiom, originally in C++, in which a class X derives from a class template instantiation using X itself as a template argument. [1] More generally it is known as F-bound polymorphism , and it is a form of F -bounded quantification .
The use of templates as a metaprogramming technique requires two distinct operations: a template must be defined, and a defined template must be instantiated.The generic form of the generated source code is described in the template definition, and when the template is instantiated, the generic form in the template is used to generate a specific set of source code.
C++ templates enable generic programming. C++ supports function, class, alias, and variable templates. Templates may be parameterized by types, compile-time constants, and other templates. Templates are implemented by instantiation at compile-time. To instantiate a template, compilers substitute specific arguments for a template's parameters to ...
Modern C++ Design: Generic Programming and Design Patterns Applied is a book written by Andrei Alexandrescu, published in 2001 by Addison-Wesley. It has been regarded as "one of the most important C++ books" by Scott Meyers. [1] The book makes use of and explores a C++ programming technique called template metaprogramming. While Alexandrescu ...
Tudor Andrei Cristian Alexandrescu [4] (born 1969) is a Romanian-American C++ and D language [3] programmer and author. He is particularly known for his pioneering work on policy-based design implemented via template metaprogramming. These ideas are articulated in his book Modern C++ Design and were first implemented in his programming library ...
The template method is used in frameworks, where each implements the invariant parts of a domain's architecture, while providing hook methods for customization. This is an example of inversion of control. The template method is used for the following reasons. [3] It lets subclasses implement varying behavior (through overriding of the hook ...
Considered harmful is a part of a phrasal template "something considered harmful". As of 2009 [update] , its snowclones have been used in the titles of at least 65 critical essays in computer science and related disciplines. [ 1 ]
