Bio::Factory::DriverFactory - Base class for factory classes loading drivers
#this class is not instantiable
This a base class for factory classes that load drivers. Normally, you don't instantiate this class directly.
User feedback is an integral part of the evolution of this and
other Bioperl modules. Send your comments and suggestions preferably
to one of the Bioperl mailing lists. Your participation is much appreciated.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : register_driver Usage : $factory->register_driver("genscan", "Bio::Tools::Genscan"); Function: Registers a driver a factory class should be able to instantiate. This method can be called both as an instance and as a class method. Returns : Args : Key of the driver (string) and the module implementing the driver (string).
Title : driver_table Usage : $table = $factory->driver_table(); Function: Returns a reference to the hash table storing associations of methods with drivers. You use this table to look up registered methods (keys) and drivers (values). In this implementation the table is class-specific and therefore shared by all instances. You can override this in a derived class, but note that this method can be called both as an instance and a class method. This will be the table used by the object internally. You should definitely know what you're doing if you modify the table's contents. Modifications are shared by _all_ instances, those present and those yet to be created. Returns : A reference to a hash table. Args :
Title : get_driver Usage : $module = $factory->get_driver("genscan"); Function: Returns the module implementing a driver registered under the given key. Example : Returns : A string. Args : Key of the driver (string).
Title : _load_module Usage : $self->_load_module("Bio::Tools::Genscan"); Function: Loads up (like use) a module at run time on demand. Example : Returns : TRUE on success Args :
