 simpleorm.simplewebapp.context.WPageContext
All known Subclasses: simpleorm.simplewebapp.context.WPageContextServlet, simpleorm.simplewebapp.context.WPageContextTest,
| WPageContext | | abstract public class WPageContext (Code) | | Peer (one to one) with WPage, Provides all the interfacing between WPage and the server.
Attempts to unify the JSP Page context with the Servlet
doGet|Post parameters.
It is always created, even if there is no page context at all (eg. if during unit tests) in which
case its methods return dummy values.
PageContext is an ugly class because it is JSP specific, and cannot
be easily used from servlets.
However, its methods are many and have a nasty relationship to
Servlet ones.
For example, PageContext.getOut() returns a different, incompatible
class to HttpServelet.getWriter().
It is unclear what the relationship of other fields such as getAttribute
really are.
This class also provides an opportunity to mock out the web server entriely
and unit test just the WebBean.
Subtypes for JSP, Servlet, Test cases.
