Class PojoWrapper<P>

Object

com.toolsverse.mvc.model.ModelImpl

com.toolsverse.mvc.pojo.PojoWrapper<P>

Type Parameters:

P - the generic type

All Implemented Interfaces:

Model, Mutable, PropertyChangeListener, Serializable, Cloneable, EventListener, javassist.util.proxy.MethodHandler

public class PojoWrapper<P>
extends ModelImpl
implements Model, javassist.util.proxy.MethodHandler

The default implementation of the Model interface ModelImpl uses name\value pairs to store model attributes instead of member variables. The PojoWrapper is designed to overcome this limitation. You can pass an any object of the type P to the PojoWrapper and it will created an instance of the class which extends P but has all it's getters, setters, readers and writers intercepted. As a result it calls ModelImpl methods such as access, populate, etc right before P own methods, so view is getting notified that model has changed and model is getting updated when view is changing. Pojo stands for Plain Java Object.
