Boxer

Annotation based serialization library for Java and Android frameworks, by generating boilerplate code.

Define classes as serializable with the <code>@Box</code> annotation.
By default all fields will be serialized, except fields with the transient modifier
the <code>@Wrap</code> annotation will wrap a <code>List</code> fields into the appropriate Subclass. (Subclass needs to have a no-args constructor)
Default non-class serialization possible

@Box
public class Example {

    private int height;
    private transient int width;
    public double weight;
    
    @Wrap(Stack.class)
    public List<Example> stack;

    //Empty constructor for Injection
    public Example(){

    }

    //Getters and Setters for private fields
}

Retrieving a <code>Boxer</code> instance, and serializing and de-serializing your data.

Example using the <code>Bundle</code> class:

public class ExampleActivity extends Activity {

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        Boxer boxer = Boxer.from(outState);
        boxer.add("Example", new Example());
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Boxer boxer = Boxer.from(savedInstanceState);
        boxer.get("Example", Example.class);
    }
}

To register your own Boxer wrapper for a specific class:

//Registering a wrapper class for a specific Target class
Boxer.registerWrapper(Wrapper.class, Target.class);

//Removing a wrapper for a specific wrapper class
Boxer.removeWrapper(Wrapper.class);

//Removing a wrapper for a target class
Boxer.removeWrapperForType(Target.class);

//Clearing all the wrappers
Boxer.clearWrappers();

TypeAdapters define how an non-Boxable class should be serialized and deserialized. TypeAdapter will need to be registered with the <code>@Adapter</code> annotation. The type parameter of the TypeAdapter should be the class you want to serialize / deserialize.

@Adapter
public class DateTypeAdapter extends TypeAdapter<Date> {

    private static final String TIME_KEY = "time_key";

    @Override
    public void serialize(Boxer<?> boxer, Date object) {
        boxer.addLong(TIME_KEY, object.getTime());
    }

    @Override
    public Date deserialize (Boxer<?> boxer) {
        return new Date(boxer.getLong(TIME_KEY));
    }
}

<code>@Serialize</code> and <code>@Deserialize</code> are used to annotate methods that will be called after or before serialization or deserialization inside <code>Boxable</code> classes.

Both annotations take an <code>Execution</code> enum as parameter to specify when they will be executed. Default execution behaviour will be after serialization or deserialization.

The method can have a <code>Boxer</code> parameter or be empty.

@Serialize
public void serialization(Boxer<?> boxer){
	//Do something
}

@Deserialize(Execution.BEFORE)
public void deserialization(Boxer<?> boxer){
	//Do something
}

Current supported supported classes:

(Android) Bundle
(Android) Parcel
(Android) SQLiteDatabase (Experimental)
(Java/Android) DataMap
