java.lang.Object

org.apache.wicket.examples.tree.FooProvider

All Implemented Interfaces:

Serializable, org.apache.wicket.extensions.markup.html.repeater.tree.ITreeProvider<Foo>, org.apache.wicket.model.IDetachable, org.apache.wicket.util.io.IClusterable

public class FooProvider
extends Object
implements org.apache.wicket.extensions.markup.html.repeater.tree.ITreeProvider<Foo>

A provider of Foos. For simplicity all foos are kept as class members, in a real world scenario these would be fetched from a database. If Foos were Serializable you could of course just keep references in instance variables.
