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:

       The rest of the documentation details each of the object methods. Internal methods are
       usually preceded with a _
