Bio::Search::HSP::HSPFactory - A factory to create Bio::Search::HSP::HSPI objects

Package variables

Included modules

Inherit

Bio::Factory::ObjectFactoryI Bio::Root::Root

Synopsis

    use Bio::Search::HSP::HSPFactory;
    my $factory = new Bio::Search::HSP::HSPFactory();
    my $resultobj = $factory->create(@args);

Description

This is a general way of hiding the object creation process so that we
can dynamically change the objects that are created by the SearchIO
parser depending on what format report we are parsing.
This object is for creating new HSPs.
