在 AS3 中使用 tree

http://developer.yahoo.com/flash/astra-flash/tree/

XML数据生成,java示例:

TreeData.java

package org.jiucai.ext.yahoo.fl.data;

import java.io.Serializable;

/**

*
* 类简介

*  3.

public class TreeData implements Serializable {
    
    private static final long serialVersionUID = 3359824250382904965L;
    private Integer id;
    private Integer parentId;
    private String name;
    private Integer treeLevel;

    
    public TreeData() {
        super();
    }


    public TreeData(Integer id, Integer parentId, String name, Integer treeLevel) {
        super();
        this.id = id;
        this.parentId = parentId;
        this.name = name;
        this.treeLevel = treeLevel;
    }
    
    
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getParentId() {
        return parentId;
    }
    public void setParentId(Integer parentId) {

    }
    public Integer getTreeLevel() {
        return treeLevel;
    }
    public void setTreeLevel(Integer treeLevel) {
