       The module represents a list of available analysis tools from a given location using a
       given access method. Additionally, for any of the available analyses, it can create an
       object of type "Bio::Tools::Run::Analysis".

       The module is a higher-level abstraction whose main job is to load a 'real-work-doing'
       implementation. Which one is used, it depends on the "-access" parameter. The same design
       is used here as for "Bio::Tools::Run::Analysis" module.

       There is available a SOAP access to almost all EMBOSS applications, running at European
       Bioinformatics Institute.

       The documentation of all "public" methods are to be found in "Bio::Factory::AnalysisI".


   Mailing Lists
       User feedback is an integral part of the evolution of this and other Bioperl modules. Send
       your comments and suggestions preferably to the Bioperl mailing list.  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.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their
       resolution. Bug reports can be submitted via the web:

       Here is the rest of the object methods.  Internal methods are preceded with an underscore

        Usage   : my $factory =
                    Bio::Tools::Run::AnalysisFactory->new(-access => 'soap',
                                                          -location => 'http://...');
        Returns : a new Bio::Tools::Run::AnalysisFactory object representing a list
                  of available analyses
        Args    : There may be additional arguments which are specific
                  to the access method (see methods 'new' or '_initialize'
                  of the access-specific implementations (such as module
                  Bio::Tools::Run::AnalysisFactory::soap for a SOAP-based access).

                  The recognised and used arguments are:

       It builds, populates and returns a new "Bio::Tools::Run::AnalysisFactory" object. This is
       how it is seen from the outside. But in fact, it builds, populates and returns a more
       specific lower-level object, for example "Bio::Tools::Run::AnalysisFactory::soap" object -
       which one it is it depends on the "-access" parameter.

           It indicates what lower-level module to load.  Default is 'soap'.  Other (but future)
           possibilities are:

              -access => 'novella'
              -access => 'local'

           A location of the service. The contents is access-specific (see details in the lower-
           level implementation modules).

           Default is "" (there are services running at
           European Bioinformatics Institute on top of most of EMBOSS analyses, and on some

           In addition to the location parameter, you may need to specify also a location/URL of
           an HTTP proxy server (if your site requires one). The expected format is
           "http://server:port".  There is no default value. It is also an access-specific
           parameter which may not be used by all access methods.

           For long(er) running jobs the HTTP connection may be time-outed. In order to avoid it
           (or, vice-versa, to call timeout sooner) you may specify "timeout" with the number of
           seconds the connection will be kept alive. Zero means to keep it alive forever. The
           default value is two minutes.

        Usage   : $class->_load_access_module ($access)
        Returns : 1 on success, undef on failure
        Args    : 'access' should contain the last part of the
                  name of a module who does the real implementation

       It does (in the run-time) a similar thing as

          require Bio::Tools::Run::AnalysisFactory::$access

       It prints an error on STDERR if it fails to find and load the module (for example, because
       of the compilation errors in the module).

        Usage   : $class->_guess_access ($rh_params)
        Returns : string with a guessed access protocol (e.g. 'soap'),
                  or undef if the guessing failed
        Args    : 'rh_params' is a hash reference containing parameters given
                  to the 'new' method.

       It makes an expert guess what kind of access/transport protocol should be used to access
       the underlying analysis. The guess is based on the parameters in rh_params. Rememeber that
       this method is called only if there was no -access parameter which could tell directly
       what access method to use.
