    • 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
      • 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

      • 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

      • 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

      • 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.
        Type Parameters:
        T - the type of EventListener class 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 listenerType doesn't specify a class or interface that implements java.util.EventListener
