);

参数

numModels

此处返回给定对象的父模型数。

返回值

此方法返回指示成功或失败的 HRESULT。

注解

代码示例

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.
}
