	use RDF::Trine::Iterator::Boolean;

	my $iterator = RDF::Trine::Iterator::Boolean->new( [1] );

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

       "new ( \@results, %args )"
       "new ( \&results, %args )"
	   Returns a new SPARQL	Result interator object. Results must be
	   either an reference to an array containing results or a CODE
	   reference that acts as an iterator, returning successive items when
	   called, and returning undef when the	iterator is exhausted.

	   $type should	be one of: bindings, boolean, graph.

	   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"
	   Returns the arguments necessary to pass to the stream constructor
	   _new	to re-create this stream (assuming the same closure as the
	   first
