Re: Template collection classes

I have read in a book about CArray, CList and CMap.
The book says that for example Carray class everytime we add an object,
MAKES a copy of the object we need to store, so we need probably to implement
a copy constructor.
But it also says as it's true, that we quite always use Reference as
Argument Type, to evitate COPIES...passing by reference,so address and not by
value.
I'm quite confusing...the copies is made or not in our CArray object?
If the copy wasn't made we would have a CArray class object that would
contain addresses or pointers, equals to CTypedPtrArray....
so for example:

CArray<CPoint, CPoint&> PointArray;

CPoint aPoint = new CPoint(...paramlist...);

PointArray.Add(aPoint);

so we pass aPoint by reference, but still we create a copy of it in
PointArray or what else?Pointarray manage only address of aPoint?
and if my declarations was:

CArray<CPoint, CPoint> PointArray;

CPoint aPoint = new CPoint(...paramlist...);

PointArray.Add(aPoint);

and also...

CArray<CPoint, CPoint*> PointArray;

CPoint aPoint = new CPoint(...paramlist...);

PointArray.Add(aPoint);

what's the difference from

CTypePtrArray<CObList,CPoint*> PointArray;

CPoint aPoint = new CPoint(...paramlist...);

PointArray.Add(aPoint);
