public class SerialUtils

extends Object

These static routines help you serialize and deserialize the primitive data types. Your own serialization routines will just be sequences of calls to these.

This implementation of serialization is much simpler and less convenient to use than the official one that will be in JDK1.1; but it has the significant albeit temporary advantage that it works in current browsers.

One thing this version does not do is handle cyclic graphs of objects. It only handles tree-shaped graphs. If you need to serialize more complicated structures, consider using an ID-based scheme - instead of having your objects contain actual references to other objects, have them contain IDs which can be translated into real references by an ID-manager class. This scheme also has the advantage that you don't have to deserialize the entire graph all at once, you can do it piece by piece as needed, and you can even set up a least-recently-used flush policy in the ID-manager.
