Java javax.swing Class AbstractListModel<E>（JDK8）

Field Detail

• listenerList

  protected EventListenerList listenerList

Constructor Detail

• AbstractListModel

  public AbstractListModel()

Method Detail

• addListDataListener

  public void addListDataListener(ListDataListener l)

  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)

  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()

  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

  1.4

• fireContentsChanged

  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

  EventListenerList, DefaultListModel

• fireIntervalAdded

  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

  EventListenerList, DefaultListModel

• fireIntervalRemoved

  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

  EventListenerList, DefaultListModel

• getListeners

  public <T extends EventListener> 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
