public abstract class LoadableModel<T>
extends Object
implements org.apache.wicket.model.IModel<T>

Lazy loading Wicket model. This is an IModel implementation that loads the model content only when needed. This is supposed to be used for objects that are expensive to load. So we can avoid loading the at all when a component that uses them is not visible.
