Ptr::Ptr

SF_INLINE Ptr(C * pobj);

The Ptr constructor initializes a new smart pointer object. The initialization is done slightly differently depending upon what value is passed to it.

• Passing a valid object pointer (e.g., Object*) causes the constructor to increment the objects reference count and store a direct pointer to that object.

   if (pobj) pobj->AddRef(); pObject = pobj;

• Passing a valid object reference (e.g., Object&) causes the constructor to assign a pointer to the object, but does not increment the objects reference count.

   pObject = &robj;

• Passing a reference to another smart pointer object (e.g., Ptr<Object>&) will cause the constructor to copy the passed objects internal object pointer, incrementing the objects reference count if the object pointer is valid.

   if (pobj) pobj->AddRef(); pObject = pobj;
