Bio::Ontology::SimpleGOEngine::GraphAdaptor

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.

add_vertex
has_vertex
add_edge
has_edge
vertices
edges
edges_at
predecessors
successors
set_vertex_attribute
get_vertex_attribute

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 AT bioperl DOT 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:
