public interface IlvPersistentObject

This interface must be implemented by objects that will be saved to JViews i/o streams. Note the following points:

• Classes implementing this interface must be public. The reason is that introspection is used by the saving and reading mechanism.
• Persistent objects must have a constructor with the signature MyPersistentObject(IlvInputStream stream) so that they can be read by IlvInputStream.
• When an object that implements this interface is stored in an IVL file, the full class name of the object is stored in the file so you must be careful not to change the class and package name of the class.
