I am going through MFC tutorials (Scribble). There is one object declared
as follows :
CTypePtrList<CObList, CStroke *> m_strokeList;
The serialise function in CScribbleDoc is declared as follows :
// TODO: add storing code here
// TODO: add loading code here
m_strokeList.Serialize( ar );
And the serialise function for "CStroke" has been defined and implemented.
What i am unable to understand is that how does the serialise function
of "CStroke" is being called when i save the document.
What i understand is that m_strokeList.Serialise() calls the serialise
function of the base class "CObject". Now how does the base class knows
that the object being serialised is list of pointes which are to be
serialised one by one so that serialise function of CStroke is called
for all pointers in the m_strokeList.
The "DECLARE_SERIAL" and "IMPLEMENT_SERIAL" macros are present in CStroke.
