| 项目描述: |
A tear-off interface maintains its own reference counting, through the CComTearOffObjectBase ATL class. Note that this is not entirely consistent with the usual COM model where the object maintains an object-wide reference count. In implementing the tear-off interface, you actually need to implement it in a separate C++ class, and instantiate this class separately from the main object class. Also, therefore, the tear-off interface doesn't feature in the multiple inheritance of the main implementation class.
ATL Tear-Off 接口通过 CComTearOffObjectBase ATL 类来维护它自己的引用计数。注意，这同一般的使用COM模型不完全一致，在后者中对象只维护对象范围内的引用计数。在tear-off 接口的实现中，你实际上需要在一个单独的C++类中实现它，从主对象类中单独实例化这个类。此外，tear-off 接口不支持主实现类的多重继承。
