METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Trine::Iterator class.

	   Returns true if the underlying result is a boolean value.

       "as_string ( $max_size [, $count] )"
	   Returns a string serialization of the stream data.

       "as_xml ( $max_size )"
	   Returns an XML serialization of the stream data.

       "print_xml ( $fh, $max_size )"
	   Prints an XML serialization of the stream data to the filehandle $fh.

       "as_json ( $max_size )"
	   Returns a JSON serialization of the stream data.
