Class ServerListTableModel

java.lang.Object
  javax.swing.table.AbstractTableModel
      org.peace_tools.data.ServerListTableModel

All Implemented Interfaces:

java.io.Serializable, javax.swing.table.TableModel, WorkspaceListener

public class ServerListTableModel
extends javax.swing.table.AbstractTableModel
implements WorkspaceListener

A bridge class between Server entries in a workspace and a JTable. This class serves as a bridge between the in-memory representation of server in a Workspace (represented by the set of classes in the workspace package). This class enables reusing the data set hierarchy maintained by the Workspace object to display it in a JTable. In addition, this class also acts to monitor and update data set views.

Note: This table model currently provides the following information for each server: Host Name, Status.
