      Enum Constants 
      Enum Constant Description
      BOOLEAN
      Boolean queries (such as the SPARQL ASK query form) return either true or false as the result.
      GRAPH
      Graph queries (such as the SPARQL CONSTRUCT and DESCRIBE query form) return a sequence of RDF statements as the result.
      TUPLE
      Tuple queries (such as the SPARQL SELECT query form) return a sequence of sets of variable bindings as the result.

        public static Query.QueryType[] 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 (Query.QueryType c : Query.QueryType.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static Query.QueryType 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
