graphnode.java

从正则表达式到NFA的JAVA实现代码

 package reg2nfa;

import java.awt.Point;

public class GraphNode {
  private int ID;     //结点的代号
  private static int id = 0;
  private Point position;    //结点在视图中的位置

  public GraphNode() {
    ID = this.id++;
    position = null;
  }
  public GraphNode(Point position) {
    this();
    this.position = position;
  }
  public static void resetID() {
    //确定结点的代号
    id = 0;
  }
  public void setPosition(Point position) {
    //确定结点在视图中的位置
    this.position = position;
  }
  public int getID() {
    return this.ID;
  }
  public Point getPosition() {
    return this.position;
  }
}
