James M Snell commented on ABDERA-168:
--------------------------------------
You could use a URI Template to do this by setting the template pattern and
passing in the current uri parameters in the context with the appropriate
changes for the page. e.g. something like:
Template template = new Template("?{-join|&|a,b,c,d,page}");
Map<String,Object> context = new HashMap<String,Object>();
context.put("a", request.getParameter("a"));
context.put("b", request.getParameter("b"));
context.put("c", request.getParameter("c"));
context.put("d", request.getParameter("c"));
context.put("page", 2);
String queryString = template.expand(context);
you can then append the expanded querystring to the base request uri

> URL: https://issues.apache.org/jira/browse/ABDERA-168
> Project: Abdera
> Issue Type: Improvement
> Affects Versions: 0.4.0
> Reporter: Remy Gendron
> Priority: Minor
>
> Hello all,
> I'm adding glue code in my application to automatically generate and add
> paging links to a returned feed.
> I have the necessary information to decide if a link should be there.
> I know how to compute the URI parameters to target another page.
> I know how to add a link to a feed with the FeedPagingHelper class.
> My question is: Is there an easy way provided by Abdera to generate the link
> by altering the current request URI parameters? I need to pass thru all the
> current parameters that define the feed content returned (eg
> ?q=xxx&author=yyy&max-results=10) but alter the start-index parameter to
> target the new page.
> I can do it manually by getting this information from the RequestContext and
> building the new link. But I see a bunch of getLink() methods in the adapter
> classes. Is there an easy (or recommended) way of generated new links based
> on the current request that I haven't seen?
> Another question would be... do you make the paging links relative to the
> base URI or do paging links need to be absolute as the examples in RFC5005
> seem to indicate?
> Thank you,
> Rémy
