MFC中的CTypedPtrList 模板怎么用？谢谢

This example creates an instance of CTypedPtrList, adds one object, serializes the list to disk, and then deletes the object:
typedef CTypedPtrList<CObList, CMyObject*> CMyList;
CMyList ml;
CMyObject* pMyObject = new CMyObject();
ml.AddTail(pMyObject);

CFileException e;
CFile myFile;
myFile.Open("MyFile.txt", CFile::modeCreate|CFile::modeWrite, &e);
CArchive ar(&myFile, CArchive::store);
ml.Serialize(ar);

ar.Close();
myFile.Close();

while (!ml.IsEmpty())
{
delete ml.GetHead();
ml.RemoveHead();
}

//=====================
//where CMyObject is defined by the following files:

//CMyObject.h
class CMyObject : public CObject
{
public:
int i;
void Serialize(CArchive& ar);
CMyObject() { i = 9876;}
protected:
DECLARE_SERIAL(CMyObject)
};

//===================
//CMyOb
