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 a think adaptor to simplify use of the old and new versions of the standard CPAN Graph module (old is versions 0.2x; new is 0.5x and beyond) within Bio::Ontology::SimpleGOEngine.

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

This class provides a 'new' method that determines which version of Graph is available. The object returned by 'new' is blessed into this class if the new version of Graph is available, else into the subclass

  Bio::Ontology::SimpleGOEngine::GraphAdaptor02

This class provides implementations for the required graph methods using the new version of Graph. In most cases, these are simple pass-throughs. Methods that differ in v0.2x are implemented in the subclass.

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

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.
