- Field Detail
  - support
```
protected Index support
```
    Support instance for delegation of some Index methods.
- Constructor Detail
  - ArrayChildren
```
public ArrayChildren()
```
    Constructor for the support.
- Method Detail
  - initCollection
```
protected java.util.List<Node> initCollection()
```
    If default constructor is used, then this method is called to lazily create the collection. Even it claims that it returns Collection only subclasses of List are valid values.
    This implementation returns ArrayList.
    
    Overrides:
    
    initCollection in class Children.Array
    
    Returns:
    
    any List collection.
  - reorder
```
public void reorder(int[] perm)
```
    Description copied from interface: Index
    
    Reorder all children with a given permutation.
    
    Specified by:
    
    reorder in interface Index
    
    Parameters:
    
    perm - permutation with the length of current nodes. The permutation lists the new positions of the original nodes, that is, for nodes [A,B,C,D] and permutation [0,3,1,2], the final order would be [A,C,D,B].
  - reorder
```
public void reorder()
```
    Invokes a dialog for reordering children using IndexedCustomizer.
    
    Specified by:
    
    reorder in interface Index
  - move
```
public void move(int x,
                 int y)
```
    Description copied from interface: Index
    
    Move the element at the x-th position to the y-th position. All elements after the y-th position are moved down.
    
    Specified by:
    
    move in interface Index
    
    Parameters:
    
    x - the position to remove the element from
    
    y - the position to insert the element to
  - exchange
```
public void exchange(int x,
                     int y)
```
    Description copied from interface: Index
    
    Exchange two elements.
    
    Specified by:
    
    exchange in interface Index
    
    Parameters:
    
    x - position of the first element
    
    y - position of the second element
  - moveUp
```
public void moveUp(int x)
```
    Description copied from interface: Index
    
    Move an element up.
    
    Specified by:
    
    moveUp in interface Index
    
    Parameters:
    
    x - index of element to move up
  - moveDown
```
public void moveDown(int x)
```
    Description copied from interface: Index
    
    Move an element down.
    
    Specified by:
    
    moveDown in interface Index
    
    Parameters:
    
    x - index of element to move down
  - indexOf
```
public int indexOf(Node node)
```
    Description copied from interface: Index
    
    Get the index of a given node.
    
    Specified by:
    
    indexOf in interface Index
    
    Parameters:
    
    node - node to find index of
    
    Returns:
    
    index of the node, or -1 if no such node was found
  - addChangeListener
```
public void addChangeListener(javax.swing.event.ChangeListener chl)
```
    Description copied from interface: Index
    
    Add a new listener to the listener list. The listener will be notified of any change in the order of the nodes.
    
    Specified by:
    
    addChangeListener in interface Index
    
    Parameters:
    
    chl - new listener
  - removeChangeListener
```
public void removeChangeListener(javax.swing.event.ChangeListener chl)
```
    Description copied from interface: Index
    
    Remove a listener from the listener list.
    
    Specified by:
    
    removeChangeListener in interface Index
    
    Parameters:
    
    chl - listener to remove
