A foo() in below source code will be accepted only the two types like myString and String2, but other types will occur an errors on compile time.

CRTP(Curiously recurring template pattern) CRTP는 클래스 X가 X 자신을 템플릿 인자로 사용하여 클래스 템플릿 인스턴스화로부터 파생되게 하는 C++ 표현(Idiom, 관용구 )이다. 이 표현 이름은 1995년에 Jim Coplien에 의해 만들어 졌다. [Wikipedia 정의] The curiously recurring template pattern (CRTP) is an idiom in C++ in which a class X derives from a class template instantiation using X itself as 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 the 1980s 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 examples that Timothy Budd created in his multiparadigm language Leda. 1. 일반적 형식 // The Curiously Recurring Template Pattern (CRTP) template < class T > class Base { // methods within Base can use template to access members of Derived }; class Derived : public Base < Derived ...
