ArrayListModel
public ArrayListModel()Constructs an empty list with an initial capacity of ten. -
ArrayListModel
public ArrayListModel(int initialCapacity) Constructs an empty list with the specified initial capacity.- Parameters:
initialCapacity
- the initial capacity of the list.- Throws:
IllegalArgumentException
- if the specified initial capacity is negative
-
ArrayListModel
Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator. TheArrayListModel
instance has an initial capacity of 110% the size of the specified collection.- Parameters:
c
- the collection whose elements are to be placed into this list.- Throws:
NullPointerException
- if the specified collection isnull

removeAll
Removes from this collection all of its elements that are contained in the specified collection (optional operation).This implementation iterates over this collection, checking each element returned by the iterator in turn to see if it's contained in the specified collection. If it's so contained, it's removed from this collection with the iterator's remove method.
Note that this implementation will throw an UnsupportedOperationException if the iterator returned by the iterator method does not implement the remove method and this collection contains one or more elements in common with the specified collection.
- Specified by:
removeAll
in interfaceCollection<E>
- Specified by:
removeAll
in interfaceList<E>
- Overrides:
removeAll
in classArrayList<E>
- Parameters:
c
- elements to be removed from this collection.- Returns:
- true if this collection changed as a result of the call.
- Throws:
UnsupportedOperationException
- if the removeAll method is not supported by this collection.NullPointerException
- if the specified collection is null.- See Also:
-
retainAll
Retains only the elements in this collection that are contained in the specified collection (optional operation). In other words, removes from this collection all of its elements that are not contained in the specified collection.This implementation iterates over this collection, checking each element returned by the iterator in turn to see if it's contained in the specified collection. If it's not so contained, it's removed from this collection with the iterator's remove method.
Note that this implementation will throw an UnsupportedOperationException if the iterator returned by the iterator method does not implement the remove method and this collection contains one or more elements not present in the specified collection.

- Overrides:

- Parameters:
c
- elements to be retained in this collection.- Returns:
- true if this collection changed as a result of the call.
- Throws:
UnsupportedOperationException
- if the retainAll method is not supported by this Collection.NullPointerException
- if the specified collection is null.- See Also:

fireContentsChanged
public final void fireContentsChanged(int index) Description copied from interface:ObservableList2
Notifies all registeredListDataListeners
that the element at the specified index has changed. Useful if there's a content change without any structural change.This method must be called after the element of the list changes.
- Specified by:
fireContentsChanged
in interfaceObservableList2<E>
- Parameters:
index
- the index of the element that has changed- See Also:
-
fireContentsChanged
public final void fireContentsChanged(int index0, int index1) Notifies all registeredListDataListeners
that the element at the specified index has changed. Useful if there's a content change without any structural change.This method must be called after one or more elements of the list change. The changed elements are specified by the closed interval index0, index1 -- the end points are included. Note that index0 need not be less than or equal to index1.
- Specified by:
fireContentsChanged
in interfaceObservableList2<E>
- Parameters:
index0
- one end of the new intervalindex1
- the other end of the new interval- Since:
- 1.7
- See Also:
-
getListDataListeners
Returns an array of all the list data listeners registered on thisArrayListModel
.- Returns:
- all of this model's
ListDataListener
s, or an empty array if no list data listeners are currently registered - See Also:
-
fireIntervalAdded
private void fireIntervalAdded(int index0, int index1) This method must be called after one or more elements are added to the model. The new elements are specified by a closed interval index0, index1 -- the end points are included. Note that index0 need not be less than or equal to index1.- Parameters:
index0
- one end of the new intervalindex1
- the other end of the new interval- See Also:
-
fireIntervalRemoved
private void fireIntervalRemoved(int index0, int index1) This method must be called after one or more elements are removed from the model.index0
andindex1
are the end points of the interval that's been removed. Note thatindex0
need not be less than or equal toindex1
.- Parameters:
index0
- one end of the removed interval, includingindex0
index1
- the other end of the removed interval, includingindex1
- See Also:
-
getEventListenerList
Lazily initializes and returns the event listener list used to notify registered listeners.- Returns:
- the event listener list used to notify listeners
-
