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.
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.
-access
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.

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.

Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
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.
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: -access -location -httpproxy -timeout
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.
Bio::Tools::Run::AnalysisFactory
Bio::Tools::Run::AnalysisFactory::soap
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 http://www.ebi.ac.uk/soaplab/services (there are services running at European Bioinformatics Institute on top of most of EMBOSS analyses, and on some others).
http://www.ebi.ac.uk/soaplab/services
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.
http://server:port
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.
timeout
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.
Usage : print $Bio::Tools::Run::AnalysisFactory::VERSION; print $Bio::Tools::Run::AnalysisFactory::Revision;
