Interface UjoExt<UJO_IMPL extends UjoExt>

All Superinterfaces:

Ujo, UjoMiddle<UJO_IMPL>

All Known Implementing Classes:

AbstractUjoExt, ArrayUjoExt, BeanUjoExt, FieldUjoExt, MapUjoExt, RegistrarUjoExt, UjoPropertyRow

public interface UjoExt<UJO_IMPL extends UjoExt>
extends UjoMiddle<UJO_IMPL>

This is an extended Ujo interface designed for a more conventional property access evaluated by developers. Most of the functions have been a similar reason like methods in the UjoProperty class. The new solution allows to the developers to chain more properties according to a model of a some new popular languages. All methods are type safe likewise the usage of the Ujo interface - exclude two methods with an unlimited count of properties: setVal(...) and getVal(...).
Sample of usage:

public class Person extends MapUjo implements UjoMiddle {

  public static final UjoProperty<Person, String > NAME = newProperty("Name", String.class);
  public static final UjoProperty<Person, Double > CASH = newProperty("Cash", Double.class);
  public static final UjoProperty<Person, Person> CHILD = newProperty("Child", Person.class);
    
  public void init() {
    set(NAME, "George");
    set(CHILD, new Person());
    set(CHILD, NAME, "Jane");
    set(CHILD, CASH, 200d);
        
    String name = get(CHILD, NAME);
    double cash = get(CHILD, CASH);
  }
}
