#define P6_REFCOUNTED ( classname )

Value:

P6_REFCOUNTED_THREADSAFE_ADDREF(classname)                                 \
P6_REFCOUNTED_THREADSAFE_RELEASE(classname)                                \
P6_REFCOUNTED_CREATEINSTANCE(classname)                                    \
P6R::P6AUTO_INT32             m_cRef

The P6_REFCOUNTED method is used to declare and implement the methods which the p6IRefCounted interface needs:

P6COMMETHOD_(P6R::P6INT32) addref()
P6COMMETHOD_(P6R::P6INT32) release()
static P6R::P6ERR createInstance(classname **ppNewComponent)

addref() and release() implement the standard P6COM reference counting semantics. createInstance() is also provided so that non-P6COM based classes can be created in the same fashion as P6COM based classes. Following this pattern has some advantages, for example it allows memory pooling (or the use of an alternate allocator of some other type) to be very easily added to the class if needed because the actual allocation is now abstracted.

Classes which derrive from p6IRefCounted MUST follow the standard P6COM reference counting semantics. It is highly recommended that classes which derrive from p6IRefCounted also be managed using the p6RefCounted<> smart pointer.

Parameters

classname The name of the class in which the reference counting methods will be decared/implemented in.
