Class com.ibm.as400.vaccess.VSystemValueList

java.lang.Object
   |
   +----com.ibm.as400.vaccess.VSystemValueList

public class VSystemValueList
extends Object
implements VNode, Serializable
The VSystemValueList class defines the representation of a system value list in an AS/400 for use in various models and panes in this package. You must explicitly call load() to load the information from the AS/400.

Most errors are reported as ErrorEvents rather than throwing exceptions. Users should listen for ErrorEvents in order to diagnose and recover from error conditions.

VSystemValueList objects generate the following events:
