BasicNotifierImpl.EAdapterList

public BasicNotifierImpl.EAdapterList(Notifier notifier)

Method Detail

canContainNull

protected boolean canContainNull()

Description copied from class: BasicEList

Returns whether null is a valid object for the list. The default is to return true, but clients can override this to exclude null.

Overrides:

canContainNull in class BasicEList<E extends java.lang.Object & Adapter>

Returns:

whether null is a valid object for the list.

useEquals

protected boolean useEquals()

Description copied from class: BasicEList

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 BasicEList<E extends java.lang.Object & Adapter>

Returns:

whether equals rather than == should be used.

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 & Adapter>

Returns:

new data storage.

didAdd

protected void didAdd(int index,
                      E newObject)

Description copied from class: BasicEList

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 BasicEList<E extends java.lang.Object & Adapter>

Parameters:

index - the position object the new object.

newObject - the new object at the position.

didRemove

protected void didRemove(int index,
                         E oldObject)

Description copied from class: BasicEList

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 BasicEList<E extends java.lang.Object & Adapter>

Parameters:

index - the position of the old object.

oldObject - the old object at the position.

data

public java.lang.Object[] data()

Description copied from class: BasicEList

Returns direct unsafe access to the underlying data storage. Clients may not modify this and may not assume that the array remains valid as the list is modified.

Overrides:

data in class BasicEList<E extends java.lang.Object & Adapter>

Returns:

direct unsafe access to the underlying data storage.

ensureSafety

protected void ensureSafety()

add

public boolean add(E object)

Description copied from class: BasicEList

Adds the object at the end of the list and returns whether the object was added; if uniqueness is required, duplicates will be ignored and false will be returned. This implementation delegates to addUnique(E) after uniqueness checking.

Specified by:

add in interface java.util.Collection<E extends java.lang.Object & Adapter>

Specified by:

add in interface java.util.List<E extends java.lang.Object & Adapter>

Overrides:

add in class BasicEList<E extends java.lang.Object & Adapter>

Parameters:

object - the object to be added.

Returns:

whether the object was added.

See Also:

BasicEList.addUnique(Object)

add

public void add(int index,
                E object)

Description copied from class: BasicEList

Adds the object at the given index in the list. If uniqueness is required, duplicates will be ignored. This implementation delegates to addUnique(int, E) after uniqueness checking.

Specified by:

add in interface java.util.List<E extends java.lang.Object & Adapter>

Overrides:

add in class BasicEList<E extends java.lang.Object & Adapter>

object - the object to be added.

See Also:

BasicEList.addUnique(int, Object)

addAll

public boolean addAll(java.util.Collection<? extends E> collection)

Description copied from class: BasicEList

Adds each object of the collection to the end of the list. If uniqueness is required, duplicates will be removed from the collection, which could even result in an empty collection. This implementation delegates to addAllUnique(Collection) after uniqueness checking.

Specified by:

addAll in interface java.util.Collection<E extends java.lang.Object & Adapter>

Specified by:

addAll in interface java.util.List<E extends java.lang.Object & Adapter>

Overrides:

addAll in class BasicEList<E extends java.lang.Object & Adapter>
