      Parameters:
      s - the string to be encoded.

      t - the URI component type identifying the ASCII characters that must be percent-encoded.
      Returns:
      the encoded string.

    • encode

    • encodeTemplateNames

      public static String encodeTemplateNames(String s)
      Encodes a string with template parameters names present, specifically the characters '{' and '}' will be percent-encoded.
      Parameters:
      s - the string with zero or more template parameters names
      Returns:
      the string with encoded template parameters names.

    • decode

      public static String decode(String s, UriComponent.Type t)
      Decodes characters of a string that are percent-encoded octets using UTF-8 decoding (if needed).

      It is assumed that the string is valid according to an (unspecified) URI component type. If a sequence of contiguous percent-encoded octets is not a valid UTF-8 character then the octets are replaced with '�'.

      If the URI component is of type HOST then any "%" found between "[]" is left alone. It is an IPv6 literal with a scope_id.

      If the URI component is of type QUERY_PARAM then any "+" is decoded as as ' '.

      Parameters:
      s - the string to be decoded.
      t - the URI component type, may be null.
      Returns:
      the decoded string.
      Throws:
      IllegalArgumentException - if a malformed percent-encoded octet is detected

    • decodeQuery

      public static MultivaluedMap<String,String> decodeQuery(URI u, boolean decode)
      Decode the query component of a URI.

      Query parameter names in the returned map are always decoded. Decoding of query parameter values can be controlled using the decode parameter flag.

      Parameters:
      u - the URI.
      decode - true if the returned query parameter values of the query component should be in decoded form.
      Returns:
      the multivalued map of query parameters.

    • decodeQuery

      public static MultivaluedMap<String,String> decodeQuery(String q, boolean decode)
      Decode the query component of a URI.

      Query parameter names in the returned map are always decoded. Decoding of query parameter values can be controlled using the decode parameter flag.

      Parameters:
      q - the query component in encoded form.
      decode - true if the returned query parameter values of the query component should be in decoded form.
      Returns:
      the multivalued map of query parameters.

    • decodeQuery

      public static MultivaluedMap<String,String> decodeQuery(String q, boolean decodeNames, boolean decodeValues)
      Decode the query component of a URI.

      Decoding of query parameter names and values can be controlled using the decodeNames and decodeValues parameter flags.

      Parameters:
      q - the query component in encoded form.
      decodeNames - true if the returned query parameter names of the query component should be in decoded form.
      decodeValues - true if the returned query parameter values of the query component should be in decoded form.
      Returns:
      the multivalued map of query parameters.

    • decodePath

      public static List<PathSegment> decodePath(URI u, boolean decode)
      Decode the path component of a URI as path segments.
      Parameters:
      u - the URI. If the path component is an absolute path component then the leading '/' is ignored and is not considered a delimiator of a path segment.
      decode - true if the path segments of the path component should be in decoded form.
      Returns:
      the list of path segments.

    • decodePath

      public static List<PathSegment> decodePath(String path, boolean decode)
      Decode the path component of a URI as path segments.

      Any '/' character in the path is considered to be a deliminator between two path segments. Thus if the path is '/' then the path segment list will contain two empty path segments. If the path is "//" then the path segment list will contain three empty path segments. If the path is "/a/" the path segment list will consist of the following path segments in order: "", "a" and "".

      Parameters:
      path - the path component in encoded form.
      decode - true if the path segments of the path component should be in decoded form.
      Returns:
      the list of path segments.

    • decodePathSegment

      public static void decodePathSegment(List<PathSegment> segments, String segment, boolean decode)
      Decode the path segment and add it to the list of path segments.
      Parameters:
      segments - mutable list of path segments.
      segment - path segment to be decoded.
      decode - true if the path segment should be in a decoded form.

    • decodeMatrix

      public static MultivaluedMap<String,String> decodeMatrix(String pathSegment, boolean decode)
      Decode the matrix component of a URI path segment.
      Parameters:
      pathSegment - the path segment component in encoded form.
      decode - true if the matrix parameters of the path segment component should be in decoded form.
      Returns:
      the multivalued map of matrix parameters.

    • isHexCharacter

      public static boolean isHexCharacter(char c)
      Checks whether the character c is hexadecimal character.
      Parameters:
      c - Any character
      Returns:
      The is c is a hexadecimal character (e.g. 0, 5, a, A, f, ...)

    • fullRelativeUri

      public static String fullRelativeUri(URI uri)
      Return the Request-Uri representation as defined by HTTP spec. For example: 
      <Method> <Request-URI> HTTP/<Version> (e.g. GET /auth;foo=bar/hello?foo=bar HTTP/1.1)
      Parameters:
      uri - uri to obtain Request-Uri from.
      Returns:
      Request-Uri representation or null if uri is not provided.
