All Implemented Interfaces:

SaveRestoreCapability, PropertyChangeListenerCapability, HibernateValidationCapability, Serializable, org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor, org.jdesktop.swingbinding.validation.ValidationCapability, DynamicIntroductionAdvice, IntroductionInfo, IntroductionInterceptor

public class PropertyChangeListenerMixin
extends DelegatingIntroductionInterceptor
implements PropertyChangeListenerCapability, SaveRestoreCapability, org.jdesktop.swingbinding.validation.ValidationCapability, HibernateValidationCapability

Mixin to enable javaBeans event support and validation in ordinary POJOs. To see each fired property change, set the log4j level for this class to debug It also contains a simple implementation of the SaveRestoreCapability. All Java bean properties of primitive or immutable (see IMMUTABLE_CLASSES) type can be saved and restored.
