All Implemented Interfaces:: UjoCloneable, UjoExt<UJO>, UjoMiddle<UJO>, UjoTextable, EventRegistrar<UJO>, Ujo

public class RegistrarUjoExt<UJO extends RegistrarUjoExt>
extends MapUjoExt<UJO>
implements EventRegistrar<UJO>
extends MapUjoExt<UJO>
implements EventRegistrar<UJO>

A MapUjoExt implementation with a Property change listener support.
There is possible to implement the EventRegistrar interface very easy to any Ujo implementation by sample:

public class RegistrarUjoExt<UJO extends RegistrarUjoExt> extends MapUjoExt<UJO> implements EventRegistrar<UJO> {
    
  final private UjoPropertyChangeSupport eventRegistrar = new UjoPropertyChangeSupport(this);

  public void writeValue(UjoProperty property, Object value) {
    Object oldValue = readValue(property);
    eventRegistrar.firePropertyChange(property, oldValue, value, true);
    super.writeValue(property, value);
    eventRegistrar.firePropertyChange(property, oldValue, value, false);
  }

  public boolean addPropertyChangeListener
    ( UjoProperty<UJO,?> property
    , Boolean before
    , UjoPropertyChangeListener listener
    ) {
    return eventRegistrar.addPropertyChangeListener(property, before, listener);
  }

  public boolean removePropertyChangeListener
    ( UjoProperty<UJO,?> property
    , Boolean before
    , UjoPropertyChangeListener listener) {
    return eventRegistrar.removePropertyChangeListener(property, before, listener);
  }
}
