All Implemented Interfaces:

TreeModel

public class SongContainerModel

extends Object

implements TreeModel

A tree model that handles the information for SongContainers. This works without making a separate tree for the song container, since the container has all the magic we need.

Constructor Summary

SongContainerModel(SongContainerElement sc)

Method Summary

void	addTreeModelListener(TreeModelListener l)
protected void	fireModifications(TreeModelEvent e, String action) Dispatch all modifications to the TreeModelListeners.
Object	getChild(Object parent, int index)
int	getChildCount(Object parent)
int	getIndexOfChild(Object parent, Object child)
Object	getRoot()
boolean	isLeaf(Object node)
void	modifiedTree(SongContainerElement el) Inform model about widespread changes to a given root.
void	modifyElement(SongContainerElement el, String action) Inform the model about altered SongContainerElements.
void	processModification(SongContainerElement el, String action) Dispatch a modification to the tree.
void	removeTreeModelListener(TreeModelListener l)
void	valueForPathChanged(TreePath path, Object newValue)

                       int index)

Specified by:

getChild in interface TreeModel

getChildCount

public int getChildCount(Object parent)

Specified by:

getChildCount in interface TreeModel

getIndexOfChild

public int getIndexOfChild(Object parent,
                           Object child)

Specified by:

getIndexOfChild in interface TreeModel

isLeaf

modifyElement

public void modifyElement(SongContainerElement el,
                          String action)

Inform the model about altered SongContainerElements. This also updates the local version of the container.

Parameters:

el - the inserted, modified, or changed element.

action - a string indicating the action. Either "insert", "remove", or "change"

modifiedTree

public void modifiedTree(SongContainerElement el)

Inform model about widespread changes to a given root.

Parameters:

el - the root which has modifications beneath it.

processModification

public void processModification(SongContainerElement el,
                                String action)

Dispatch a modification to the tree. This calls either modifyElement or modifiedTree as appropriate.

Parameters:

action - "structure", "insert", "remove", or "change"

fireModifications

protected void fireModifications(TreeModelEvent e,
                                 String action)

Dispatch all modifications to the TreeModelListeners.

valueForPathChanged

public void valueForPathChanged(TreePath path,
                                Object newValue)

Specified by:

valueForPathChanged in interface TreeModel
