I'm trying to use the serialization library to implement the undo/redo
functionality. Basically, the idea is like this:
// create the object...
// before modify the object, save it first.
ar << pObject;
// modify the object...
// undo the modification from the archive
ar >> pObject;
The problem is that after the undo, pObject will point to a newly
created object instead of the originally. (The same applies some pointer
fields of the object.)
Any quick solution? (Maybe, when loading a pointer, the library will not
create a new object if the pointer is not equal to 0?)
