Detailed Description
template<typename I, typename R, typename X>
class comstl::interface_cast_base< I, R, X >
Base class for the interface cast classes comstl::interface_cast_noaddref and comstl::interface_cast_addref.
This class serves only as a base, and cannot be used in isolation
- Parameters:
-
I The interface pointer type R The release type X The exception type

Construction | |
| template<typename J> | |
| interface_cast_base (J &j, NullThrowPermission permission) | |
| Constructor that attempts the speculative cast. | |
| interface_cast_base (interface_pointer_type pi) | |
| Constructor that directly casts (without calling QueryInterface()). | |
| ~interface_cast_base () throw () | |
Releases the acquired interface pointer according to the release_type policy. | |
Accessors | |
| interface_pointer_type const & | get_pointer_ () |
| Returns a non-mutating reference to the acquired interface pointer. | |
| interface_pointer_type | get_pointer_ () const |
| Returns a copy of the acquired interface pointer. | |
