javax.swing
Class AbstractListModel<E>

java.lang.Object
  javax.swing.AbstractListModel<E>

Type Parameters:

E - the type of the elements of this model

All Implemented Interfaces:

Serializable, ListModel<E>

Direct Known Subclasses:

BasicDirectoryModel, DefaultComboBoxModel, DefaultListModel, MetalFileChooserUI.DirectoryComboBoxModel, MetalFileChooserUI.FilterComboBoxModel

public abstract class AbstractListModel<E>
extends Object
implements ListModel<E>, Serializable

Disabled: no SafeJ information.

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 XMLEncoder.

Method Summary

void	addListDataListener(ListDataListener l) Adds a listener to the list that's notified each time a change to the data model occurs.
protected void	fireContentsChanged(Object source, int index0, int index1) AbstractListModel subclasses must call this method after one or more elements of the list change.
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.
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.
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.

Method Detail

addListDataListener

public void addListDataListener(ListDataListener l)

Class is disabled.

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

Specified by:

addListDataListener in interface ListModel<E>

Parameters:

l - the ListDataListener to be added

removeListDataListener

public void removeListDataListener(ListDataListener l)

Class is disabled.

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

Specified by:

removeListDataListener in interface ListModel<E>

Parameters:

l - the ListDataListener to be removed

getListDataListeners

public ListDataListener[] getListDataListeners()

Class is disabled.

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

Since:

1.4

fireContentsChanged

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

Class is disabled.

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:

EventListenerList, DefaultListModel

fireIntervalAdded

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

Class is disabled.

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:

EventListenerList, DefaultListModel

fireIntervalRemoved

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

Class is disabled.

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

getListeners

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

Class is disabled.

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

Since:

1.3
