Constructor Details

AbstractListModel

public AbstractListModel()
Creates a new model instance - initialises the event listener list.

Method Details

addListDataListener

public void addListDataListener(ListDataListener listener)
Add a listener object to this model. The listener will be called any time the set of elements in the model is changed.
Specified by:
addListDataListener in interface ListModel
Parameters:
listener - The listener to add

extends EventListener> T[] getListeners

public extends EventListener> T[] getListeners(Class listenerType)
Return the subset of EventListener objects found in this object's listenerList which are elements of the specified type.
Parameters:
listenerType - The type of listeners to select
Returns:
The set of listeners of the specified type

fireContentsChanged

protected void fireContentsChanged(Object source,
                                   int startIndex,
                                   int endIndex)
Call ListDataListener.contentsChanged(ListDataEvent) on each element of the listenerList which is a ListDataListener. The event fired has type ListDataEvent.CONTENTS_CHANGED and represents a change to the data elements in the range [startIndex, endIndex] inclusive.
Parameters:
source - The source of the change, typically this
startIndex - The index of the first element which changed
endIndex - The index of the last element which changed

fireIntervalAdded

protected void fireIntervalAdded(Object source,
                                 int startIndex,
                                 int endIndex)
Call ListDataListener.intervalAdded(ListDataEvent) on each element of the listenerList which is a ListDataListener. The event fired has type ListDataEvent.INTERVAL_ADDED and represents an addition of the data elements in the range [startIndex, endIndex] inclusive.
Parameters:
source - The source of the change, typically this
startIndex - The index of the first new element
endIndex - The index of the last new element

fireIntervalRemoved

protected void fireIntervalRemoved(Object source,
                                   int startIndex,
                                   int endIndex)
Call ListDataListener.intervalRemoved(ListDataEvent) on each element of the listenerList which is a ListDataListener. The event fired has type ListDataEvent.INTERVAL_REMOVED and represents a removal of the data elements in the range [startIndex, endIndex] inclusive.
Parameters:
source - The source of the change, typically this
startIndex - The index of the first element removed
endIndex - The index of the last element removed

getListDataListeners

public ListDataListener[] getListDataListeners()
A synonym for getListeners(ListDataListener.class).
Returns:
The set of ListDataListeners found in the listenerList

removeListDataListener

public void removeListDataListener(ListDataListener listener)
Add a listener object to this model. The listener will no longer be called when the set of elements in the model is changed.
Specified by:
removeListDataListener in interface ListModel
Parameters:
listener - The listener to remove
