      • decode

        public static java.lang.String decode​(java.lang.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:
        java.lang.IllegalArgumentException - if a malformed percent-encoded octet is detected

        Parameters:
        q - the query component in encoded form.

        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 java.util.List<org.atmosphere.util.uri.UriComponent.PathSegmentImpl> decodePath​(java.lang.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.

      • decodeMatrix

        public static java.util.Map<java.lang.String,​java.lang.String> decodeMatrix​(java.lang.String pathSegment,

        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.
