Examples of PageParameters

org.apache.wicket.PageParameters
A typesafe abstraction and container for parameters to a requested page. Page parameters in HTTP are query string values in the request URL. In other protocols, the parameters to a page might come from some other source.
Pages which take a PageParameters object as an argument to their constructor can be accessed directly from a URL and are known as "bookmarkable" pages since the URL is stable across sessions and can be stored in a browser's bookmark database. @author Jonathan Locke
org.apache.wicket.request.mapper.parameter.PageParameters
Mutable class that holds parameters of a Page. Page parameters consist of indexed parameters and named parameters. Indexed parameters are URL segments before the query string. Named parameters are usually represented as query string params (i.e. ?arg1=var1&arg2=val)
Indexed vs Named Parameters: Suppose we mounted a page on {@code /user} and thefollowing url was accessed {@code /user/profile/bob?action=view&redirect=false}. In this example {@code profile} and {@code bob} are indexed parameters with respective indexes 0 and 1.{@code action} and {@code redirect} are named parameters.

How those parameters are populated depends on the {@link IRequestMapper}s @author Matej Knopp
