NAME

       Bio::Ontology::SimpleGOEngine::GraphAdaptor - Graph adaptor for Bio::Ontology::SimpleGOEngine

SYNOPSIS

         use Bio::Ontology::SimpleGOEngine::GraphAdaptor;

         my $graph = Bio::Ontology::SimpleGOEngine::GraphAdaptor;

DESCRIPTION

       This is an adaptor to simplify use of versions of the standard CPAN Graph module (old is versions 0.2x;
       new is 0.5x and beyond) within Bio::Ontology::SimpleGOEngine. Prior versions of this module supported
       Graph version older than 0.5, however we are removing support for these older version post BioPerl
       1.6.901. If you absolutely require an old version of Graph, please use an older version of BioPerl.

       This module implements only those Graph methods used by SimpleGOEngine. It is far from a complete
       compatibility layer! It also implements workarounds for certain performance problems in the current
       versions of Graph v0.5x.

       This class provides implementations for the required graph methods using the new version of Graph. In
       most cases, these are simple pass-throughs

       The methods implemented here or in the subclasses are listed below.  In all cases, we implemented the
       Graph v0.5x interface.  Consult the Graph v0.5x man page for details.

FEEDBACK

   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 lists  Your participation is much appreciated.

   Support
       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.

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