Bio::Ontology::SimpleGOEngine::GraphAdaptor(3) Graph adaptor for

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
  set_edge_attribute
  get_edge_attribute
  source_vertices
  sink_vertices

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:

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.
