Annotation Type Entity

@Retention(value=RUNTIME)
@Documented
@Target(value=TYPE)
public @interface Entity

@Entity is a marker annotation to tell Acid House that the annotated class is an entity class to be managed by Acid House. Entity is a POJO (Plain Old Java Object), and can represent a hierarchical structure (not relationship) as the ownership of member objects. The hierarchy is appropriately mapped to the datastore-specific data model by ResourceManager implementation, like this:

 @Entity
 public class Entity3 {
 
        @Key String id;
 
        int i;
 
        Entity1 entity1;
 
        List<Entity2> entity2s;
 
 }
 
 @Entity
 public class Entity1 {
 
        @Key String id;
 
        int i;
 
 }
 
 @Entity
 public class Entity2 {
 
        @Key String id;
 
        List<Integer> integers;
 
 }
