I don't know...Link is a special case and can't be handled by the
HeaderDelegate directly.
Consider this header:
Link: <http:...>; rel="edit", <http:...>; rel="next";
void foo(@HeaderParam("Link") String links,
@HeaderParam("Link") Link[] links)
In Resteasy we have a LinkHeader class that represents one HTTP Link
header. LInkHeader serves up multiple Link objects. Its a very literal
interpretation of things. Our ClientResponse has a getLink(String rel)
method, but on the server side, users inject a LinkHeader object.
Maybe what exists in the spec is simpler and we should handle the split
of comma delimited things internally? I don't know...
