C++ tips - inclusion rule
C++ INCLUDE Rule : Use forward declaration when possible
Suppose you want to define a new class B that uses objects of class A.- B only uses references or pointers to A. Use forward declaration then : you don't need to include
. This will in turn speed a little bit the compilation. class A ; class B { private: A* fPtrA ; public: void mymethod(const& A) const ; } ;
- B derives from A or B explicitely (or implicitely) uses objects of class A. You then need to include
#include
class B : public A { } ; class C { private: A fA ; public: void mymethod(A par) ; }
