  ULONG64 *numModels
);

Parameters

numModels

The number of parent models of the given object is returned here.

This method returns HRESULT that indicates success or failure.

Remarks

Code Sample

ComPtr<IModelObject> spObject; /* get an object */

ULONG64 numModels;
if (SUCCEEDED(spObject->GetNumberOfParentModels(&numModels)))
{
    // numModels contains the number of immediate parent models (does not include 
    // grand-parents and further generations up).  If a key is queried on spObject and 
    // that instance does not have it, the query will be passed in turn to each of the
    // 'numModels' models which are attached to spObject.
}
