Class GroupModel

java.lang.Object
  javax.swing.table.AbstractTableModel
      edu.northwestern.at.wordhoard.swing.accounts.groups.GroupModel

All Implemented Interfaces:

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

public class GroupModel
extends javax.swing.table.AbstractTableModel

Group model.

Each group panel has a model which acts as a Swing table model, manages all communications with the server session, and maintains the following state information for the panel:

• The list of all current groups.
• The current selection - an array of indexes in the list of the selected groups.
• Whether or not we are currently creating a new userGroup.

Window components register listeners on the model to listen for and react appropriately to changes in the state of the window.
