[gme-users] cloning of models using BON

[Zoltan Molnar]

Oh, sorry. BON1 might not have such functionality implemented, but the
underlying COM functionality allows easy implementation of it:

The COM methods of IMgaModel look like this:
		HRESULT MoveFCOs([in] IMgaFCOs * to_copy, [in]
IMgaMetaRoles *destroles, [out] IMgaFCOs **objs);
		HRESULT CopyFCOs([in] IMgaFCOs * to_move, [in]
IMgaMetaRoles *destroles, [out] IMgaFCOs **objs); 


So a helper method to benefit from these could look like this:
void copy( CBuilderModel* where_to_copy, CBuilderObject *to_copy)
{
	CComPtr<IMgaFCO>   src_obj = to_copy->getIObject();
	CComPtr<IMgaModel> par_obj = where_to_copy->GetIModel();

	CComPtr<IMgaFCOs>       fco_coll;  // ptr to a collection of
IMgaFCO objects
	CComPtr<IMgaMetaRoles>  rol_coll;  // same
	fco_coll.CoCreateInstance( L"Mga.MgaFCOs");        // create an
empty 'array' of MgaFCO objects
	rol_coll.CoCreateInstance( L"Mga.MgaMetaRoles"));  // same

	// fco collection with 1 element
	fco_coll->Append( src_obj);

	CComPtr<IMgaMetaRole> role;
	src_obj->get_MetaRole(&role);
	
	// role collection with 1 element
	rol_coll->Append( role); // based on the assumption that the
parent of src_obj is of same or similar kind to par_obj

	CComPtr<IMgaFCOs> dst_coll;
	par_obj->CopyFCOs( fco_coll, rol_coll, &dst_coll);

	// analyze dst_coll
	long l = 0;
	if( dst_coll) dst_coll->get_Count( &l);
	for( int i = 1; i <= l; ++i)
	{
		CComPtr<IMgaFCO> dst;
		dst_coll->get_Item( i, &dst);
	}
}

Let me know if you need something else,
