Android-NoSql

用于安卓的轻量级的简单结构的NoSQL数据库

Download

dependencies {

compile 'com.github.florent37:android-nosql:1.0.0'

}

Save your datas as a structured tree

noSql.put("/users/", "florent")

noSql.put("/users/", "kevin")

nosql.put("/identifiers/florent", 10)

nosql.put("/identifiers/kevin", 12)

The data structure will be

/

---users/

---"florent"

---"kevin"

---identifiers/

---florent/

---10

---kevin/

---12

It’ll be simple to search data

int myId = noSql.get("/identifiers/florent/").integer();

Serialize objects

You can simply add nodes from POJOS

final User user = new User(

"flo",

new House("paris"),

Arrays.asList(new Car("chevrolet camaro"), new Car("ford gt"))

);

noSql.put("/user/florent/", user);

/

---users/

---florent/

---name/

---"flo"

---house/

---adress/

---"paris"

---cars/

---0/

---model/

---"chevrolet camaro"

---1/

---model/

---"ford gt"

Get Objects from node

Or fetch nodes directly into Java Objects

User user = noSql.get("/user/florent/", User.class);

Navigate

noSql.node("/identifiers/")

.child("florent")

.childNodes()

.get(1)

.put("country", "france");

Listeners

You can listen for nodes updates

noSql.notify("/user/", new Listener() {

@Override

public void nodeChanged(String path, NoSql.Value value) {

//notified when :

// - the node is created

// - the node is deleted

// - a subnode is added / updated

}

});

Init

Android-NoSql need DataSavers to store your objets

public class MainApplication extends Application {

@Override

public void onCreate() {

super.onCreate();

AndroidNoSql.initWith(

new SharedPreferencesDataSaver(getSharedPreferences("test", Context.MODE_PRIVATE))

);

}

}

It means you can store your data into SharedPreference, or SqlDatabase, or any storage library your want ?
