I need to add a multiple descriptor to a file package.
If i want to add a normal descriptor i do this:
FilePackage->AddChild(Descriptor_UL)->MakeLink (WrapConfig->EssenceDescriptor);


So if i want to add a multiple descriptor i think that i should do this:
MDObjectPtr multipleDescriptor=new MDObject(MultipleDescriptor_UL);

multipleDescriptor->addChild(SubDescriptor_UL)->MakeLink(WrapConfigA->EssenceDescriptor);

multipleDescriptor->addChild(SubDescriptor_UL)->MakeLink(WrapConfigB->EssenceDescriptor);

FilePackage->AddChild(multipleDescriptor);

is this the right way?thx

ok. This code is wrong and i found the right code in the mxfwrap application. it is something like this:
mxflib::MDObjectPtr multipleDescriptor=new mxflib::MDObject(mxflib::MultipleDescriptor_UL);

multipleDescriptor->AddChild(mxflib::SubDescriptorUIDs_UL);

mxflib::MDObjectPtr subDescriptorA=WrapConfigA->EssenceDescriptor;

multipleDescriptor[mxflib::SubDescriptorUIDs_UL]->AddChild()->MakeRef(subDescriptorA);

mxflib::MDObjectPtr subDescriptorB=WrapConfigB->EssenceDescriptor;

multipleDescriptor[mxflib::SubDescriptorUIDs_UL]->AddChild()->MakeRef(subDescriptorB);

sourcePackage->AddChild(mxflib::Descriptor_UL)->MakeRef(multipleDescriptor);
