Interface ObservableCollection<V>

Type Parameters:

V - the type of the Collection values

All Superinterfaces:

Collection<V>, Iterable<V>

All Known Subinterfaces:

NamedBlockingDeque<E>, NamedBlockingQueue<E>, NamedDeque<E>, NamedQueue<E>

public interface ObservableCollection<V>
extends Collection<V>

ObservableCollection interface represents an object with a model being a Collection that allows for pluggable notifications for occurring changes.

Method Summary

Modifier and Type	Method	Description
void	addListener(CollectionListener<? super V> listener)	Add a standard collection listener that will receive all events (inserts, updates, deletes) that occur against the collection, with the old-value and new-value included.
void	addListener(CollectionListener<? super V> listener, Filter<V> filter, boolean fLite)	Add a collection listener that receives events based on a filter evaluation.
void	removeListener(CollectionListener<? super V> listener)	Remove a standard collection listener that previously signed up for all events.
void	removeListener(CollectionListener<? super V> listener, Filter<V> filter)	Remove a collection listener that previously signed up for events based on a filter evaluation.

Method Details

addListener

void addListener(CollectionListener<? super V> listener)

Add a standard collection listener that will receive all events (inserts, updates, deletes) that occur against the collection, with the old-value and new-value included. This has the same result as the following call:

   addListener(listener, (Filter) null, false);
 

Parameters:

listener - the CollectionEvent listener to add

removeListener

void removeListener(CollectionListener<? super V> listener)

Remove a standard collection listener that previously signed up for all events. This has the same result as the following call:

   removeListener(listener, (Filter) null);
 

Parameters:

listener - the listener to remove

addListener

void addListener(CollectionListener<? super V> listener,
 Filter<V> filter,
 boolean fLite)

Add a collection listener that receives events based on a filter evaluation.

The listeners will receive CollectionEvent objects, but if fLite is passed as true, they might not contain the OldValue and NewValue properties.

To unregister the Listener, use the removeListener(CollectionListener, Filter) method.

Parameters:

listener - the CollectionEvent listener to add

filter - a filter that will be passed CollectionEvent objects to select from; a CollectionEvent will be delivered to the listener only if the filter evaluates to true for that CollectionEvent (see MapEventFilter); null is equivalent to a filter that always returns true

fLite - true to indicate that the CollectionEvent objects do not have to include the OldValue and NewValue property values in order to allow optimizations

removeListener

void removeListener(CollectionListener<? super V> listener,
 Filter<V> filter)

Remove a collection listener that previously signed up for events based on a filter evaluation.

Parameters:

listener - the listener to remove

filter - the filter that was passed into the corresponding addCollectionListener() call
