Bio::DB::GFF::Aggregator::none -- No aggregation
use Bio::DB::GFF; # Open the sequence database my $db = Bio::DB::GFF->new( -adaptor => 'dbi:mysql', -dsn => 'dbi:mysql:elegans42', -aggregator => 'none' );
Bio::DB::GFF::Aggregator::none can be used to indicate that you do not want any aggregation performed. It is equivalent to providing undef to the -aggregator argument. It overrides disaggregate() and aggregate() so that they do exactly nothing.
