org.apache.wicket.model
Class AbstractPropertyModel<T>

java.lang.Object
  org.apache.wicket.model.AbstractPropertyModel<T>

Type Parameters:

T - The Model object type

All Implemented Interfaces:

Serializable, IClusterable, IChainingModel<T>, IDetachable, IModel<T>, IObjectClassAwareModel<T>, IPropertyReflectionAwareModel

Direct Known Subclasses:

PropertyModel

public abstract class AbstractPropertyModel<T>
extends Object
implements IChainingModel<T>, IObjectClassAwareModel<T>, IPropertyReflectionAwareModel

Serves as a base class for different kinds of property models. By default, this class uses PropertyResolver to resolve expressions on the target model object. Note that the property resolver by default provides access to private members and methods. If guaranteeing encapsulation of the target objects is a big concern, you should consider using an alternative implementation.
