node.java

有关java的一个简单树

package com.util;

public class Node {
  NodeList m_childNodes;
  Node m_parentNode;
  String m_text, m_link;
  String m_id, m_parentId;

  public Node(String id, String parentId, String text, String link){
    m_childNodes = new NodeList();
    m_id = id;
    m_parentId = parentId;
    m_text = text;
    m_link = link;
  }

  public String getId(){
    return m_id;
  }

  public String getParentId(){
    return m_parentId;
  }

  public void addChild(Node child){
    child.setParentNode(this);
    m_childNodes.addNode(child.getId(), child);
  }

  public NodeList getChildNodes(){
    return m_childNodes;
  }

  public boolean hasChilds(){
    return m_childNodes.getElements().hasNext();
  }

  public String getText(){
    return m_text;
  }

  public void setText(String text){
    m_text = text;
  }

  public String getLink(){
    return m_link;
  }

  public void setLink(String link){
    m_link = link;
  }

  public Node getParentNode(){
    return m_parentNode;
  }

  public void setParentNode(Node parentNode){
    m_parentNode = parentNode;
  }
}
