* Proxy/Stub macros
*
* The follwoing macros can be used to implement Proxy/Stub classes for
* classes that support only one or more interfaces other then IUnknown
* (and maybe IDebug). The resulting classes will support IProxy, IStub
* interface in addition to the interfaces supported by the original class.
* Assuming the interfaces supported is IName and it is implemented
* by a class CName:
*
* Declaration (in *.h):
*
* class CName { class CNameProxy { class CNameStub {
* ............ ............ ............
* STDUNKDECL(CName,Name) STDUNKDECL(CNameProxy,NameProxy) STDUNKDECL(CNameStub,NameStub)
* STDDEBDECL(CName,Name) STDDEBDECL(CNameProxy,NameProxy) STDDEBDECL(CNameStub,NameStub)
* STDPROXYDECL(CNameProxy,NameProxy) STDSTUBDECL(NameStub,1)
* <IName Declaration> <IName for proxy> <IName for stub>
* ............ ............ ............
* }; }; };
*
* Implementation (in *.cpp):
*
* For original object:
*
* STDUNKIMPL(Name)
*
* STDUNK_QI_IMPL(Name,Name)
*
* STDUNKIMPL_FORDERIVED(Name,NameImpl)
*
* <Implementation of IName: CNameImpl>
