returning undef when the iterator is exhausted.
$type should be one of: bindings, boolean, graph.
- "is_boolean"
- 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.
- "construct_args"
