Class SortableListModel

java.lang.Object
  javax.swing.AbstractListModel
      javax.swing.DefaultListModel
          project35.util.SortableListModel

All Implemented Interfaces:

Serializable, ListModel

public class SortableListModel
extends DefaultListModel

One shortfall of DefaultListModel is there is no easy way to sort the items. With a Vector you can employ the Collections.sort() convenience method but then you lose update notifications. This is simply a DefaultListModel with a sort function.

Constructor Detail

SortableListModel

public SortableListModel()

DefaultListModel has but one constructor.

Method Detail

sort

public void sort()

Sort the items in the list - logic is:

1. Check if already sorted and if so return
2. Export a Vector, sort, reimport

The screen redraw is the slow part here, assuming the list is not vast.
As with Collections.dort all objects must be comparable

sort

public void sort(Comparator comparator)

As per sort() but you may specify a comparator.

Parameters:

comparator - The comparator to use.

add

public void add(Object obj)

Make add(Object) call addElement(obj)

Parameters:

obj - The object to add

remove

public void remove(Object obj)

Make remove(Object) call

Parameters:

obj - The object to remove
