    • Method Detail

      • values

        public static SPARQL[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (SPARQL c : SPARQL.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static SPARQL valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • escape

        public static java.lang.String escape​(java.lang.String theString)
        Properly escape out any special characters in the query string. Replaces unescaped double quotes with \" and replaces slashes '\' which are not a valid escape sequence such as \t or \n with a double slash '\\' so they are unescaped correctly by a SPARQL parser.
        Parameters:
        theString - the query string to escape chars in
        Returns:
        the escaped query string
