      Implementation of mapRequestToDataset(String) that looks for the longest match in the registry. This includes use in direct naming GSP.
    • wholeRequestURL

      public static String wholeRequestURL(javax.servlet.http.HttpServletRequest request)
      Calculate the full URL including query string for the HTTP request. This may be quite long.

    • removeContextPath

      public static String removeContextPath(HttpAction action)
    • actionURI

      public static String actionURI(javax.servlet.http.HttpServletRequest request)
      Returns:
      the URI without context path of the webapp and without query string.
    • contentNegotation

      public static MediaType contentNegotation(HttpAction action, AcceptList myPrefs, MediaType defaultMediaType)
      Negotiate the content-type and set the response headers
    • contentNegotationRDF

      public static MediaType contentNegotationRDF(HttpAction action)
      Negotiate the content-type for an RDF triples syntax and set the response headers
    • contentNegotationQuads

      public static MediaType contentNegotationQuads(HttpAction action)
      Negotiate the content-type for an RDF quads syntax and set the response headers
    • splitOnComma

      public static String[] splitOnComma(String string)
      Split a string on "," and remove leading and trailing whitespace on each element
    • splitContains

      public static boolean splitContains(String[] elts, String str)
    • parseOrError

      public static void parseOrError(HttpAction action, StreamRDF dest, Lang lang, String base)
      Parse RDF content from the body of the request of the action, ends the request, and sends a 400 if there is a parse error.
      Throws:
      ActionErrorException
    • parse

      public static void parse(HttpAction action, StreamRDF dest, Lang lang, String base)
      Parse RDF content. This wraps up the parse step reading from an action. It includes handling compression if the Content-Encoding header is present
      Throws:
      RiotParseException
