// scoped_nsobject<> is patterned after scoped_ptr<>, but maintains ownership // of an NSObject subclass object. Style deviations here are solely for // compatibility with scoped_ptr<>'s interface, with which everyone is already // familiar. // // When scoped_nsobject<> takes ownership of an object (in the constructor or // in reset()), it takes over the caller's existing ownership claim. The // caller must own the object it gives to scoped_nsobject<>, and relinquishes // an ownership claim to that object. scoped_nsobject<> does not call // -retain. template <typename NST> class scoped_nsobject { public: typedef NST* element_type;
// scoped_nsobject<>::release() is like scoped_ptr<>::release. It is NOT // a wrapper for [object_ release]. To force a scoped_nsobject<> object to // call [object_ release], use scoped_nsobject<>::reset().
