Method Detail

install

public void install(ca.odell.glazedlists.EventList<E> source)

Adds this AbstractListEventListener as a listener on the source EventList. Installation this way is required in order to guarantee that the ListEventListener has a cache of the current contents of the list so it can call itemRemoved(Object, int, EventList) with the correct items.

itemAdded

protected abstract void itemAdded(E item,
                                  int idx,
                                  ca.odell.glazedlists.EventList<E> source)

Notification that an item was added.

itemRemoved

protected abstract void itemRemoved(E item,
                                    int idx,
                                    ca.odell.glazedlists.EventList<E> source)

Notification that an item was removed.

itemUpdated

protected abstract void itemUpdated(E item,
                                    E priorItem,
                                    int idx,
                                    ca.odell.glazedlists.EventList<E> source)
