IModelKeyReference::SetKey method (dbgmodel.h)
The SetKey method on a key reference behaves as the SetKey method on IModelObject would. It will assign the value of the key. If the original key was a property accessor, this will replace the property accessor. It will not call the SetValue method on the property accessor.
Syntax
HRESULT SetKey(
IModelObject *object,
IKeyStore *metadata
);
Parameters
object
The value to assign to the key.
metadata
Optional metadata to be associated with the key.
Return value
This method returns HRESULT that indicates success or failure.
Remarks
Code Sample
ComPtr<IDataModelManager> spManager; /* get the data model manager */
ComPtr<IModelObject> spObject; /* get an object */
ComPtr<IModelKeyReference> spKeyRef;
if (SUCCEEDED(spObject->GetKeyReference(L"Id", &spKeyRef, nullptr)))
{
VARIANT vtValue;
vtValue.vt = VT_UI8;
vtValue.ullVal = 42;
ComPtr<IModelObject> sp42;
if (SUCCEEDED(spManager->CreateIntrinsicObject(ObjectIntrinsic, &vtValue, &sp42)))
{
if (SUCCEEDED(spKeyRef->SetKey(sp42.Get(), nullptr)))
{
// The "Id" key has been overwritten with the value 42.
// If the "Id" key originally was a property accessor, it isn't anymore.
// This would not have called SetValue() on the property accessor.
// It replaced the property accessor with a static "42".
}
}
}
