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 =3D new Template("?{-join|&|a,b,c,d,page}");
  Map<String,Object> context =3D 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 =3D template.expand(context);

you can then append the expanded querystring to the base request uri

> 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 l=
ink by altering the current request URI parameters? I need to pass thru all=
 the current parameters that define the feed content returned (eg ?q=3Dxxx&=
author=3Dyyy&max-results=3D10) but alter the start-index parameter to targe=
t 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 ad=
apter 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,
