Method Detail

getNotifier

public java.lang.Object getNotifier()

Description copied from class: NotifyingListImpl

Returns null.

Specified by:

getNotifier in interface NotifyingList<E extends java.lang.Object & EObject>

Overrides:

getNotifier in class NotifyingListImpl<E extends java.lang.Object & EObject>

Returns:

null.

getFeatureID

public int getFeatureID()

Description copied from class: NotifyingListImpl

Returns Notification.NO_FEATURE_ID.

Specified by:

getFeatureID in interface NotifyingList<E extends java.lang.Object & EObject>

Overrides:

getFeatureID in class NotifyingListImpl<E extends java.lang.Object & EObject>

Returns:

Notification.NO_FEATURE_ID.

See Also:

Notification.getFeatureID(java.lang.Class<?>)

isNotificationRequired

protected boolean isNotificationRequired()

Description copied from class: NotifyingListImpl

Returns false.

Overrides:

isNotificationRequired in class NotifyingListImpl<E extends java.lang.Object & EObject>

Returns:

false.

useEquals

protected boolean useEquals()

Description copied from class: AbstractEList

Returns whether equals rather than == should be used to compare members. The default is to return true but clients can optimize performance by returning false. The performance difference is highly significant.

Overrides:

useEquals in class AbstractEList<E extends java.lang.Object & EObject>

Returns:

whether equals rather than == should be used.

hasInverse

protected boolean hasInverse()

Description copied from class: NotifyingListImpl

Returns false.

Overrides:

hasInverse in class NotifyingListImpl<E extends java.lang.Object & EObject>

Returns:

false.

isUnique

protected boolean isUnique()

Description copied from class: AbstractEList

Returns whether objects are constrained to appear at most once in the list. The default is to return false, but clients can override this to ensure uniqueness of contents. The performance impact is significant: operations such as add are O(n) as a result requiring uniqueness.

Overrides:

isUnique in class AbstractEList<E extends java.lang.Object & EObject>

Returns:

whether objects are constrained to appear at most once in the list.

inverseAdd

public NotificationChain inverseAdd(E object,
                           NotificationChain notifications)

Description copied from class: NotifyingListImpl

Does nothing and returns the notifications. Clients can override this to update the inverse of a bidirectional relation.

Overrides:

inverseAdd in class NotifyingListImpl<E extends java.lang.Object & EObject>

Parameters:

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

notifications - the chain of accumulating notifications.

Returns:

the notifications.

inverseRemove

public NotificationChain inverseRemove(E object,
                              NotificationChain notifications)

Description copied from class: NotifyingListImpl

Does nothing and returns the notifications. Clients can override this to update the inverse of a bidirectional relation.

Overrides:

inverseRemove in class NotifyingListImpl<E extends java.lang.Object & EObject>

Parameters:

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

notifications - the chain of accumulating notifications.

Returns:

the notifications.

newData

protected java.lang.Object[] newData(int capacity)

Description copied from class: BasicEList

Returns new allocated data storage. Clients may override this to create typed storage. The cost of type checking via a typed array is negligible.

Overrides:

newData in class BasicEList<E extends java.lang.Object & EObject>

Returns:

new data storage.

didAdd

protected void didAdd(int index,
          E object)

Description copied from class: AbstractEList

Called to indicate that an object has been added to the data storage. This implementation does nothing; clients can use this to monitor additions to the data storage.

Overrides:

didAdd in class AbstractEList<E extends java.lang.Object & EObject>

Parameters:

index - the position object the new object.

object - the new object at the position.

didRemove

protected void didRemove(int index,
             E object)

Description copied from class: AbstractEList

Called to indicate that an object has been removed from the data storage. This implementation does nothing; clients can use this to monitor removals from the data storage.

Overrides:

didRemove in class AbstractEList<E extends java.lang.Object & EObject>

Parameters:

index - the position of the old object.

object - the old object at the position.

didSet

protected void didSet(int index,
          E newObject,
          E oldObject)

Description copied from class: AbstractEList

Called to indicate that the data storage has been set. This implementation does nothing; clients can use this to monitor settings to the data storage.

Overrides:

didSet in class AbstractEList<E extends java.lang.Object & EObject>

Parameters:

index - the position that was set.

newObject - the new object at the position.

oldObject - the old object at the position.

didClear

protected void didClear(int oldSize,
            java.lang.Object[] oldData)

Description copied from class: AbstractEList

Called to indicate that the data storage has been cleared. This implementation calls didRemove for each object; clients can use this to monitor clearing of the data storage.

Overrides:

didClear in class AbstractEList<E extends java.lang.Object & EObject>

Parameters:

oldSize - the original size of the list.

oldData - the old data storage being discarded.

See Also:

AbstractEList.didRemove(int, E)

loaded

protected void loaded()

modified

protected void modified()

contains

public boolean contains(java.lang.Object object)

Description copied from class: BasicEList

Returns whether the list contains the object. This implementation uses either equals or "==" depending on useEquals.

Specified by:

contains in interface java.util.Collection<E extends java.lang.Object & EObject>

Specified by:

contains in interface java.util.List<E extends java.lang.Object & EObject>

Overrides:

contains in class BasicEList<E extends java.lang.Object & EObject>

Parameters:

object - the object in question.

Returns:

whether the list contains the object.
