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 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(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(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
