Class Overview

The abstract definition for the data model that provides a List with its contents.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.

Summary

Fields

Public Constructors
AbstractListModel()
Public Methods
void addListDataListener(ListDataListener l)
Adds a listener to the list that's notified each time a change to the data model occurs.
ListDataListener[] getListDataListeners()
Returns an array of all the list data listeners registered on this AbstractListModel.
<T extends EventListener> T[] getListeners(Class<T> listenerType)
Returns an array of all the objects currently registered as FooListeners upon this model.
void removeListDataListener(ListDataListener l)
Removes a listener from the list that's notified each time a change to the data model occurs.
Protected Methods
void fireContentsChanged(Object source, int index0, int index1)
AbstractListModel subclasses must call this method after one or more elements of the list change.
void fireIntervalAdded(Object source, int index0, int index1)
AbstractListModel subclasses must call this method after one or more elements are added to the model.
void fireIntervalRemoved(Object source, int index0, int index1)

Public Methods

public void addListDataListener (ListDataListener l)

Adds a listener to the list that's notified each time a change to the data model occurs.

Parameters
l the ListDataListener to be added

public ListDataListener[] getListDataListeners ()

Returns an array of all the list data listeners registered on this AbstractListModel.

Returns
  • all of this model's ListDataListeners, or an empty array if no list data listeners are currently registered
See Also

public T[] getListeners (Class<T> listenerType)

Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.

You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a list model m for its list data listeners with the following code: 

ListDataListener[] ldls = (ListDataListener[])(m.getListeners(ListDataListener.class));
If no such listeners exist, this method returns an empty array.

Parameters
listenerType the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener
Returns
  • an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added
Throws
ClassCastException if listenerType doesn't specify a class or interface that implements java.util.EventListener
See Also

public void removeListDataListener (ListDataListener l)

Removes a listener from the list that's notified each time a change to the data model occurs.

Parameters
l the ListDataListener to be removed

Protected Methods

protected void fireContentsChanged (Object source, int index0, int index1)

AbstractListModel subclasses must call this method after one or more elements of the list change. The changed elements are specified by the closed interval index0, index1 -- the endpoints are included. Note that index0 need not be less than or equal to index1.

Parameters
source the ListModel that changed, typically "this"
index0 one end of the new interval
index1 the other end of the new interval
See Also

protected void fireIntervalAdded (Object source, int index0, int index1)

AbstractListModel subclasses must call this method after one or more elements are added to the model. The new elements are specified by a closed interval index0, index1 -- the enpoints are included. Note that index0 need not be less than or equal to index1.

Parameters
source the ListModel that changed, typically "this"
index0 one end of the new interval
index1 the other end of the new interval
See Also

protected void fireIntervalRemoved (Object source, int index0, int index1)

AbstractListModel subclasses must call this method after one or more elements are removed from the model. index0 and index1 are the end points of the interval that's been removed. Note that index0 need not be less than or equal to index1.

Parameters
source the ListModel that changed, typically "this"
index0 one end of the removed interval, including index0
index1 the other end of the removed interval, including index1
