One way of doing object cloning is to design your object so that all of the
important values are exposed as properties, and to write a generic property
copying method. Then you simply create a new object of the same class as the
original object, and then copy over all of the properties. This provides for
a fairly quick and dirty cloning mechanism that relies on minimal code to
achieve. Assuming you have:
TMyBaseObject = class(TObject)
end;
TMyBaseClass = class of TMyBaseObject;
then you can do the following to any decendant of TMyBaseObject:
NewObject = TMyBaseObject(OldObject.ClassType).Create;
CopyProperties(OldObject, NewObject);
and you'll have a cloned copy. As an excercise to the readr I'll leave
writing the copy properties procedure, and handling properties with
undesirable side effects.
Cheers, Max.
