Constructor & Destructor Documentation

CRTP()

template<typename Derived>

model::CRTP< Derived >::CRTP ( )

inline

The default constructor.

Sample use:

#include <iostream>
#include <CRTP.h>
 
template <typename Derived>
class BaseClass : public CRTP<Derived>{
       public:
       void print() const {std::cout<<"Base class of DerivedClass"<< this->p_derived()->id()<<std::endl;}
};
 
class DerivedClass1 : public BaseClass<DerivedClass1>{
       public:
       int id() const {return 1;}
};
 
class DerivedClass2 : public BaseClass<DerivedClass2>{
       public:
       int id() const {return 2;}
};
 
int main(){
       DerivedClass1 dc1;
       DerivedClass2 dc2;
       dc1.print();
       dc2.print();
}
