Remarks

DummyGraduatedMarkerLayer implements ILayer, but does not implement all of its members.  The only members implemented are ILayer.Cached (Get only), ILayer.Valid and ILayer.Visible (Get Only).  If you try to call any other members, you'll get an error, HRESULT of E_NOTIMPL in C++.  In VB, this is Error 445,  "Object doesn't support this action".

 

DummyGraduatedMarkerLayer does not implement ILegendInfo.SymbolsAreGraduated (Put).  It you attempt to call this member you'll get an error, HRESULT of E_NOTIMPL in C++.  In VB, this is Error 445,  "Object doesn't support this action".

DummyGraduatedMarkerLayer is the one and only instance of its class.
