Enc Curiously Recurring Template Pattern

Enc Curiously Recurring Template Pattern - The Curiously Recurring Template Pattern CRTP CRTP is a powerful static alternative to virtual functions and traditional inheritance that can be used to give types properties at compile time It works by having a base class template which takes as one of its template parameters the derived class This permits it to legally perform a static

Enc Curiously Recurring Template Pattern

Usage of VPtr and VTable can be avoided altogether through Curiously Recurring Template Pattern (CRTP). CRTP is a design pattern in C++ in which a class X derives from a class template instantiation using X itself as template argument. More generally it is known as F-bound polymorphism. See this for above result.

In short CRTP is when a class A has a base class which is a template specialization for the class A itself E g template class T class X class A public X A It is curiously recurring isn t it Now what does this give you This actually gives the X template the ability to be a base class for its specializations For example you could make a generic singleton class

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 technique was formalized in 1989 as F bounded

C Practical Uses For The Curiously Recurring Template Pattern

The Curiously Recurring Template Pattern is an interesting technique at least to know and sometimes to use With the help of the pattern you access the derived class public interface from the base class which helps you mostly adding functionality to a derived class through the base implementing polymorphism without the cost of virtual tables

C++ has a long, outstanding history of tricks and idioms. One of the oldest is the curiously recurring template pattern (CRTP) identified by James Coplien in 1995 [ Coplien ].Since then, CRTP has been popularized and is used in many libraries, particularly in Boost [ Boost ].For example, you can find it in Boost.Iterator , Boost.Python or in Boost.Serialization libraries.
