基于java的3d开发库。对坐java3d的朋友有很大的帮助。

public class Flag
{
    private static boolean loading = false;
    
    private Flag() {
        ;
    }
    
    public static synchronized void set_done() {
        System.out.println("Flag.set_done");
        if (!loading)
            System.out.println("flag was false, should have been true");
        loading = false;
    }
    
    public static synchronized void set_loading() {
        System.out.println("Flag.set_loading");
        loading = true;
    }
    
    public static synchronized boolean still_loading() {
        System.out.println("Flag.still_loading");
        return loading;
    }
}
