       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.


   Mailing Lists
       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.
                  - General discussion  - About the mailing lists

       Please direct usage questions or support issues to the mailing list:

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.

       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

        Returns :
        Args    : Key of the driver (string) and the module implementing the driver

        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    :
