javax.swing.AbstractListModel

public abstract class javax.swing

AbstractListModel

Java SE 6

Extended by: BasicDirectoryModel, DefaultComboBoxModel, DefaultListModel, MetalFileChooserUI.DirectoryComboBoxModel, MetalFileChooserUI.FilterComboBoxModel

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 JavaBeans^TM has been added to the java.beans package. Please see java.beans.XMLEncoder.

Constructors

AbstractListModel()

Methods

public void

addListDataListener(ListDataListener l)
Adds a listener to the list that's notified each time a change to the data model occurs.

l	the `ListDataListener` to be added

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.

source	the `ListModel` that changed, typically "this"
index0	one end of the new interval
index1	the other end of the new interval
See also	javax.swing.event.EventListenerList, javax.swing.DefaultListModel

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.

source	the `ListModel` that changed, typically "this"
index0	one end of the new interval
index1	the other end of the new interval
See also	javax.swing.event.EventListenerList, javax.swing.DefaultListModel

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.

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`
See also	javax.swing.event.EventListenerList, javax.swing.DefaultListModel

public void

removeListDataListener(ListDataListener l)
Removes a listener from the list that's notified each time a change to the data model occurs.

l	the `ListDataListener` to be removed

Properties

public ListDataListener[]

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

return	all of this model's `ListDataListener`s, or an empty array if no list data listeners are currently registered
since	1.4
See also	addListDataListener, removeListDataListener

public EventListener[]<T>

getListeners(Class 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.

listenerType	the type of listeners requested; this parameter should specify an interface that descends from `java.util.EventListener`
return	an array of all objects registered as `FooListener`s 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`
since	1.3
