- Type Parameters:
- E- the type of the elements of this model

 public abstract class AbstractListModel<E> extends Object implements ListModel<E>, Serializable The abstract definition for the data model that provides aListwith 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.beanspackage. Please seeXMLEncoder.- Since:
- 1.2

Method Detail- 
addListDataListenerpublic void addListDataListener(ListDataListener l) Adds 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
 
 - 
removeListDataListenerpublic void removeListDataListener(ListDataListener l) Removes 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
 
 - 
getListDataListenerspublic ListDataListener[] getListDataListeners() Returns 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

fireContentsChangedprotected void fireContentsChanged(Object source, int index0, int index1) AbstractListModelsubclasses 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:
- EventListenerList,- DefaultListModel
 
 - 
fireIntervalAddedprotected void fireIntervalAdded(Object source, int index0, int index1) AbstractListModelsubclasses 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- ListModelthat changed, typically "this"
- index0- one end of the new interval
- index1- the other end of the new interval
- See Also:
- EventListenerList,- DefaultListModel
 
 - 
fireIntervalRemovedprotected void fireIntervalRemoved(Object source, int index0, int index1) AbstractListModelsubclasses 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
- See Also:
- EventListenerList,- DefaultListModel

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

- 1.3
