Detailed Description

template<typename T>
class SafeBool< T >

template class SafeBool use CRTP to made boolean conversion easy and correct.

Derived class should implement the function bool toBool() const to make this work. Inheritance should be public.

Template Parameters:
TType of the derived class
 class A : public SafeBool<A> { 
 public:
 
      // boolean conversion
      bool toBool() { 
      
      }  
 };
 
 class B : public SafeBool<B> { 
 public:
 
      // boolean conversion
      bool toBool() const { 
      
      }  
 };
 
 A a;
 B b;
 
 // will compile 
 if(a) { 
 
 }
 
 // compilation error 
 if(a == b) { 
 
 }
