Enclosing class:

ItemProvider

public class ItemProvider.ItemProviderNotifyingArrayList<E>
extends NotifyingListImpl<E>

This class overrides the "notify" methods to fire INotifyChangedListener calls and it overrides the "inverse basic" methods to maintain referential integrity by calling IUpdateableItemParent.setParent.

Constructor Summary

ItemProvider.ItemProviderNotifyingArrayList()
This constructs an empty instance.

ItemProvider.ItemProviderNotifyingArrayList(java.util.Collection<? extends E> collection)
This constructs an instance with the same initial content as the given collection.

ItemProvider.ItemProviderNotifyingArrayList(int initialCapacity)
This constructs an instance with this initial capacity.

Method Summary

protected NotificationImpl	createNotification(int eventType, java.lang.Object oldObject, java.lang.Object newObject, int index, boolean wasSet) This implementation creates an ItemProvider.ItemProviderNotification.
protected NotificationChain	createNotificationChain(int capacity) Creates a notification chain, if the expected capacity exceeds the threshold at which a list is better than chaining individual notification instances.
protected void	dispatchNotification(Notification notification) This implementation directs the notification the containing item provider.
protected boolean	hasInverse() This has an inverse
protected NotificationChain	inverseAdd(java.lang.Object object, NotificationChain notifications) This implementation will call IUpdateableItemParent.setParent, if appropriate.
protected NotificationChain	inverseRemove(java.lang.Object object, NotificationChain notifications) This implementation will call IUpdateableItemParent.setParent, if appropriate.
protected boolean	isNotificationRequired() This always notifies.

Constructor Detail

ItemProvider.ItemProviderNotifyingArrayList

public ItemProvider.ItemProviderNotifyingArrayList()

This constructs an empty instance.

ItemProvider.ItemProviderNotifyingArrayList

public ItemProvider.ItemProviderNotifyingArrayList(int initialCapacity)

This constructs an instance with this initial capacity.

ItemProvider.ItemProviderNotifyingArrayList

public ItemProvider.ItemProviderNotifyingArrayList(java.util.Collection<? extends E> collection)

This constructs an instance with the same initial content as the given collection. Note that the add methods are called to do this and hence calls to basic methods are produced. This means there will be notification, but you can make sure the domain notifier is null during this constructor invocation to change that behaviour. All the basic item provider constructors ensure that no domain events are fired.

Method Detail

isNotificationRequired

protected boolean isNotificationRequired()

This always notifies.

Overrides:

isNotificationRequired in class NotifyingListImpl<E>

Returns:

false.

hasInverse

protected boolean hasInverse()

This has an inverse

Overrides:

hasInverse in class NotifyingListImpl<E>

Returns:

false.

dispatchNotification

protected void dispatchNotification(Notification notification)

This implementation directs the notification the containing item provider.

Overrides:

dispatchNotification in class NotifyingListImpl<E>

Parameters:

notification - the notification to dispatch.

createNotification

protected NotificationImpl createNotification(int eventType,
                                              java.lang.Object oldObject,
                                              java.lang.Object newObject,
                                              int index,
                                              boolean wasSet)

This implementation creates an ItemProvider.ItemProviderNotification.

Overrides:

createNotification in class NotifyingListImpl<E>

Parameters:

eventType - the type of change that has occurred.

oldObject - the value of the notifier's feature before the change occurred.

newObject - the value of the notifier's feature after the change occurred.

index - the position at which the change occurred.

Returns:

a new notification.

createNotificationChain

protected NotificationChain createNotificationChain(int capacity)

Description copied from class: NotifyingListImpl

Creates a notification chain, if the expected capacity exceeds the threshold at which a list is better than chaining individual notification instances.

Overrides:

createNotificationChain in class NotifyingListImpl<E>

inverseAdd

protected NotificationChain inverseAdd(java.lang.Object object,
                                       NotificationChain notifications)

This implementation will call IUpdateableItemParent.setParent, if appropriate.

Overrides:

inverseAdd in class NotifyingListImpl<E>

Parameters:

object - the object that's been added to the list.

notifications - the chain of accumulating notifications.

Returns:

the notifications.

inverseRemove

protected NotificationChain inverseRemove(java.lang.Object object,
                                          NotificationChain notifications)

This implementation will call IUpdateableItemParent.setParent, if appropriate.

Overrides:

inverseRemove in class NotifyingListImpl<E>

Parameters:

object - the object that's been remove from the list.

notifications - the chain of accumulating notifications.

Returns:

the notifications.
