向greenDAO实体添加自定义代码 [英] Adding custom code to greenDAO entities

问题描述

我想向我的greenDAO实体添加一些自定义代码.我看到那里有一些保护区.但是我不喜欢将生成的类检入到git存储库中的想法.我想为此使用继承.

I want to add some custom code to my greenDAO entities. I saw there is something like protected regions. But I don't like the idea to check in the generated classes to my git repository. I'd like to use inheritance for this.

即我有一个实体User.因此，我希望greenDAO生成一个名为UserBase的类.我想通过User扩展并实现这样的方法:

i.e. I have an entity User. So I want greenDAO to generate a class called UserBase. This I want to extend by User and implement a method like this:

public String getFullName() {
    return this.first + " " + this.last;
}

其中first和last是托管属性.

但是我不知道如何告诉greenDAO使用类User而不是生成的实体UserBase.有什么办法吗?

But I have no idea how to tell greenDAO to use the class User instead of the generated entity UserBase. Is there any way to do this?

推荐答案

我找到了一种解决方法:

I found a way how to solve this:

您可以为每个实体输入一个上级:

you can enter a parent for each entity:

Entity user = schema.addEntity("User");
...
user.setSuperclass("UserBase");

因此，您可以将UserBase实现为抽象类.

So you can implement the UserBase as an abstract class.

public abstract class UserBase {

  public String getFullName() {
    return getFirst() + " " + getLast();
  }

  public abstract int getFirst();
  public abstract int getLast();
}

这里的缺点是，必须将生成的getter声明为抽象方法才能访问它们.

The disadvantage here is, that you have to declare the generated getters as abstract methods to access them.
