/**
The VUser class defines the representation of a user on a
system for use in various models and panes in this package.
You must explicitly call load() to load the information from
the system.
Most errors are reported as ErrorEvents rather than
throwing exceptions. Users should listen for ErrorEvents
in order to diagnose and recover from error conditions.
VUser objects generate the following events:
- ErrorEvent
- PropertyChangeEvent
- VObjectEvent
- WorkingEvent
@deprecated Use Java Swing instead, along with the classes in package com.ibm.as400.access
