TOB 6 编程界面重大简化

TOB 6 的编程界面最近完成了一次重大简化, 附件是更新后的持久应用样板程序, 用6.0的SUN JDK和1.6.5或更新的Apache Ant就可以编译.

简化后的持久类模样从下面代码可见一斑, 特别注意 getAllProducts() 的实现.
完整项目源码在附件zip中.

            subcate.getO().enlistProducts(l);
    }

    public List<Product> getAllProducts()
    {
        List<Product> all = new ArrayList<Product>(100);
        this.enlistProducts(all);
        return Collections.unmodifiableList(all);
    }

    public String getName()
    {
        return this.name;
    }

    @Writing
    public void setName(String name)
    {
        this.name = name;
    }

    public String getDesciption()
    {
        return this.description;
    }

    @Writing
    public void setDescription(String desc)
    {

    }

}

TestBookStore 的OrderQ.STATUS 和TestContant的UserQ.NAME等这是什么表示法啊
JDK5.0无法编译通过,只能使用JDK6.0?

编译时TOB自动生成用于拼装SQL的查询条件类, 对应应用自己的持久类名, 后面加个 Q.

TOB 6 是基于 JSR 269 的 Annotation Processor 的, 所以必须是JDK 6才行. 不过这样其实简化了编译步骤, 和平常javac/ant没有什么差别了, 原来5的时候还必须用apt编译才行的.
