YoDao
============

YoDao Is A Simple and Fast ORM library for android.

Usage
-----

Step 1: Write your model, use JAP(Java Persistence API) style.

```java
    package com.yoda.yodao.test.model;

import com.yoda.yodao.annotation.Column;
    import com.yoda.yodao.annotation.Entity;
    import com.yoda.yodao.annotation.GeneratedValue;
    import com.yoda.yodao.annotation.GenerationType;
    import com.yoda.yodao.annotation.Id;
    import com.yoda.yodao.annotation.Table;

@Entity
    @Table(name="user")
    public class User {

@Id
      @GeneratedValue(strategy = GenerationType.AUTO)
      private long id;

@Column(name = "name")
      private String name;

@Column(name = "age")
      private long age;

public long getId() {
        return id;
      }

public void setId(long id) {
        this.id = id;
      }

public String getName() {
        return name;
      }

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

public long getAge() {
        return age;
      }

public void setAge(long age) {
        this.age = age;
      }
    }
```

Step 2: Write your DAO interface. (Yes, just a interface)

```java
    package com.yoda.yodao.test.dao;

import java.util.List;

import com.yoda.yodao.YoDao;
    import com.yoda.yodao.annotation.Repository;
    import com.yoda.yodao.test.model.User;

@Repository
    public interface UserDao extends YoDao<User> {

List<User> findByNameAndAge(String name, int age);

User findOneByNameAndAge(String name, int age);

User findOneByNameOrderByAge(String name);

}
```

Step 3: Just use this Dao in your code, Yodao will generate all the codes for your, include create table, Dao implements Class.

```java
    UserDao userDao = DaoFactory.create(UserDao.class, openHelper);

// Query
    List<User> users = userDao.findAll();
    users = userDao.findByNameAndAge("Jackson", 23);
    user = userDao.findOneByName("Jackson")

// Insert
    User uesr = new User();
    user.setName("Jackson");
    user.setAge(23);
    userDao.save(user);

// Update
    user.setName("Jack");
    userDao.save(user);

// Delete
    userDao.delete(user.getId());
    userDao.deleteAll();
```

Performance
-----------

Yodao is very fast, because it uses annotation processing to generate all codes for you, just like [Butterknife](https://github.com/JakeWharton/butterknife), and [Dagger](https://github.com/square/dagger) .
