Curiously recurring
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. More generally it is known as F-bound polymorphism, and it is a form of F-bounded quantification. See more The technique was formalized in 1989 as "F-bounded quantification." The name "CRTP" was independently coined by Jim Coplien in 1995, who had observed it in some of the earliest C++ template code as well as in code … See more The main purpose of an object counter is retrieving statistics of object creation and destruction for a given class. This can be easily solved using CRTP: Each time an object of class X is created, the constructor of counter is called, incrementing both … See more When using polymorphism, one sometimes needs to create copies of objects by the base class pointer. A commonly used idiom for this is adding a virtual clone function that is defined in every derived class. The CRTP can be used to avoid … See more Some use cases for this pattern are static polymorphism and other metaprogramming techniques such as those described by Andrei Alexandrescu See more Typically, the base class template will take advantage of the fact that member function bodies (definitions) are not instantiated until long after their declarations, and … See more Method chaining, also known as named parameter idiom, is a common syntax for invoking multiple method calls in object-oriented … See more • Barton–Nackman trick • F-bounded quantification See more WebSep 29, 2008 · The memory usage gains are a negligible proportion of overall memory usage for us. I can't see how it can be used. Polymorhpishm works by using a base class pointer to call derived class methods according to the type of the derived class. However in the CRTP code you still have to template< typename derived > class base { public: void …
