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
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
 has been added to the java.beans package.

Method Details- 
addListDataListenerAdds a listener to the list that's notified each time a change to the data model occurs.- Specified by:
- addListDataListenerin interface- ListModel<E>
- Parameters:
- l- the- ListDataListenerto be added
 
- 
removeListDataListenerRemoves a listener from the list that's notified each time a change to the data model occurs.- Specified by:
- removeListDataListenerin interface- ListModel<E>
- Parameters:
- l- the- ListDataListenerto be removed
 
- 
getListDataListenersReturns an array of all the list data listeners registered on thisAbstractListModel.- Returns:
- all of this model's ListDataListeners, or an empty array if no list data listeners are currently registered
- Since:
- 1.4

- 
fireContentsChangedAbstractListModelsubclasses 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- ListModelthat changed, typically "this"
- index0- one end of the new interval
- index1- the other end of the new interval
- See Also:
 
- 
fireIntervalAddedAbstractListModelsubclasses 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 endpoints are included. Note that index0 need not be less than or equal to index1.- Parameters:
- source- the- ListModelthat changed, typically "this"
- index0- one end of the new interval
- index1- the other end of the new interval
- See Also:
 
- 
fireIntervalRemovedAbstractListModelsubclasses must call this method after one or more elements are removed from the model.index0andindex1are the end points of the interval that's been removed. Note thatindex0need not be less than or equal toindex1.- Parameters:
- source- the- ListModelthat changed, typically "this"
- index0- one end of the removed interval, including- index0
- index1- the other end of the removed interval, including- index1

getListenersReturns an array of all the objects currently registered asFooListeners upon this model.FooListeners are registered using theaddFooListenermethod.You can specify the listenerTypeargument with a class literal, such asFooListener.class. For example, you can query a list modelmfor 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.- Type Parameters:
- T- the type of- EventListenerclass being requested
- 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- listenerTypedoesn't specify a class or interface that implements- java.util.EventListener
