Annotation Type Factory

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

Defines a Supplier used to create a particular Entity class. By default the persistence processor will generate a factory that creates the type using the default zero argument constructor, however it may be desirable to have an entity with constructor parameters. When that this the case this annotation must be specified on the entity defining a Supplier class that will instantiate the entity. Example:

     @Entity
     @Factory(PhoneFactory.class)
     public class AbstractPhone {
         String phone;
         AbstractPhone(String phone) {
             this.phone = phone
         }
     }
     ...
     public class PhoneFactory implements Factory<Phone> {
         @Override
         public Phone create() {
            return new Phone("555-5555");
         }
     }
