    • parseParameters

      public static void parseParameters(Map map, byte[] data, String encoding, boolean isPost) throws UnsupportedEncodingException
      Append request parameters from the specified String to the specified Map. It is presumed that the specified Map is not accessed from any other thread, so no synchronization is performed.

      IMPLEMENTATION NOTE: URL decoding is performed individually on the parsed name and value elements, rather than on the entire query string ahead of time, to properly deal with the case where the name or value includes an encoded = or & character that would otherwise be interpreted as a delimiter. NOTE: byte array data is modified by this method. Caller beware.

      Parameters:
      map - Map that accumulates the resulting parameters
      data - Input string containing request parameters
      encoding - Encoding to use for converting hex
      Throws:
      UnsupportedEncodingException - if the data is malformed
