Jentiti

An IoC container.

Annotations

@Entity(value = [Name for entity], scope = [“singleton” or "prototype"]) // Could be used on public Classes or Annotations.

@Singleton(value = [Name for singleton entity]) // Could be used on public Classes or Annotations.

@Prototype(value = [Name for prototype entity]) // Could be used on public Classes or Annotations.

@Jsonify // Enhance toString() method for an entity to return JSON string.

(Example)

@Entity(scope = "singleton")
@Jsonify
public class User{
    ...fields...
    ...methods...
    etc.
}

IoC container

When you instantiated an EntityContext object. Entities are loaded to the container or you would call it a factory. You can use method get([Entity name or class]) to get the entity you need.

(Example)

public static void main(String[] args){
    EntityContext context = new EntityContext();
    User user = (User) context.get("user");
    System.out.println(user);
}

Expansion

You can do some extra enhancement to an entity or some entities by implementing EntityPostProcessor. Once your class implements this interface, the method postInstantiation would be invoked during instantiation of entities.

package org.jentiti.xtend.intf;

public interface EntityPostProcessor {

    Object postInstantiation(Object entity);
}
