Detailed Description
template<typename Base = IUnknown>
class COM::ObjectBase< Base >
The base class for all COM objects.
This provides an implementation of IUnknown for dynamically allocated objects. It also marks the interface as supporting COM exceptions which are handled automatically by the macro COM_CATCH_* in ErrorInfo.hpp.
