Examples of org.apache.wicket.Request

org.apache.wicket.Request
Base class for page request implementations allowing access to request parameters. A Request has a URL and a parameter map. You can retrieve the URL of the request with getURL(). The entire parameter map can be retrieved via getParameterMap(). Individual parameters can be retrieved via getParameter(String). If multiple values are available for a given parameter, they can be retrieved via getParameters(String). @author Jonathan Locke
