Class VSystemStatus

  +--com.ibm.as400.vaccess.VSystemStatus

All Implemented Interfaces:

java.io.Serializable, javax.swing.tree.TreeNode, VNode, VObject

public class VSystemStatus

extends java.lang.Object

implements VNode, java.io.Serializable

The VSystemStatus class defines the representation of system status on an AS/400 for use in various models and panes in this package. The method load() must be explicitly called 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.

VSystemStatus objects generate the following events:

• ErrorEvent
• PropertyChangeEvent
• VObjectEvent
• WorkingEvent
