As we discuss earlier (2000/09/22), we added a method createObject() to
allow to extend peers. This method is like this. And as we discuss, we
thought we only will overload the createObject() method in the subclass.
protected static createObject()
{
return new MyDataObject();
}
SubMyPeer extends MyPeer.
If I call SubMyPeer.doSelect(), it really calls the MyPeer.doSelect(). In
the code, it calls the createObject() (in fact MyPeer.createObject())method
and not the SubMyPeer because it is static.
The problem is that all the methods in peers are static.
Did I misunderstood something or did we miss this problem when we discuss
this point ??
Any idea to resolve that ?
