As for the implementation of selectors, I'm thinking of something like:
public interface ResultSelector {
public ResultConfig chooseResult(String resultCode, List
matchingResultConfigs, ActionInvocation inv);
}
then you could have:
* o.a.s.dispatcher.UserAgentResultSelector
* o.a.s.dispatcher.ContentTypeResultSelector
* o.a.s.dispatcher.RequestAttributeResultSelector
and so on. Perhaps these would be executed in a chain, such that the
user agent selector would get the first shot, but if not found, return
null, so the content type selector is called next, and so on.
This may be a good start, but how will this deal with the case when
the result depends on 2 (or more conditions)?
Well, it wouldn't in that version. What if we turned it around so that
the selector looked like this:
public interface ResultSelector {
public String determineWhen(ActionInvocation inv);
}
Then, each result selector is given a chance to select a single String.
If a result has when="modern-browser,partial-html",
the each selector will be given a chance to return its "when" token, and
xwork will match them together as AND.
