Bio::Graph::Edge(3pm)

Bio::Graph::Edge - encapsulation of an interaction between 2 Bio::Seq objects

  ## get an interaction between two nodes ##

  my $edge  = $gr->edge( $gr->nodes_by_id('P12345'),
                         $gr->nodes_by_id('P23456'));
  my $id    = $edge->object_id();
  my $wt    = $edge->weight();
  my @nodes = $edge->nodes();

This class contains information about a bimolecular interaction. At present it just contains data about its component node, a weight (if set) and an identifier. Subclasses could hold more specific information.
