What is the use of class CTypedPtrArray?

Hi,
In CTypedPtrArray description in msdn, it is said that it can hold objects of CObArray or CPtrArray. But I am not able to figure out how they have implemented it. I mean how can they restrict which class we will be using as the base class. Why cant I give my own class if I implemented the functions of CTypedPtrArray in my code?

CObArray contains an array of CObject objects. You derive your class from CObject.
