=item C<< sse >>

Returns the SSE string for this algebra expression.

=cut

sub sse {
	my $self	= shift;
	my $context	= shift;

	return sprintf(
		'(%s %s)',
		$self->op,
		join(' ', map { $_->sse( $context ) } $self->operands),
	);
}

=item C<< as_sparql >>

Returns the SPARQL string for this algebra expression.

=cut

sub as_sparql {
	my $self	= shift;
	my $context	= shift;
	my $indent	= shift;
	my $op		= $self->op;
	my @args	= map { $_->as_sparql( $context, $indent ) } $self->operands;
	return join(" $op ", @args);
