Examples of org.apache.wicket.request.RequestParameters

org.apache.wicket.request.RequestParameters

Object that abstracts common request parameters. It consists of possible optional parameters that can be translated from e.g. servlet request parameters and serves as a strongly typed variant of these that is to be created by the {@link org.apache.wicket.request.IRequestCycleProcessor}'s {@link org.apache.wicket.request.IRequestCodingStrategy}.

Though this object can be extended and hence more parameter options can be used, anything other than in this implementation must be supported by specific {@link org.apache.wicket.request.IRequestCycleProcessor} implementations and thus are notsupported by default implementations.
