Detailed Description

No-op reference counting policy.

This class is intended to be used as a "policy" argument to a host class template that implements no-op reference counting. That class would then inherit privately from it like so:

   template <class RefCountPolicy>
   class MyHostClass : private RefCountPolicy
   {
   public:
     void my_add_ref (void)    { this->RefCountPolicy::add_ref (); }
     void my_remove_ref (void) { this->RefCountPolicy::remove_ref (); }
   };

and use it like so:

   typedef MyHostClass<TAO::Null_RefCount_Policy> MyNonRefCountedClass;
   MyNonRefCountedClass m;
   ...

Note:

In order to incur no size overhead on the host class due to virtual tables, no base class defining an interface is defined. This allows C++ compilers to apply the Empty Base Class Optimization.
