Subclass of System::SmartPtr which sets itself to weak mode at construction. Please note that this class doesn't guarantee that its instance will always remain in weak mode as set_Mode() is still accessible. This type is a pointer to manage other object's deletion. It should be allocated on stack and passed to functions either by value or by const reference. More...
