       Bio::Ontology::Path - a path for an ontology term graph


         $path = Bio::Ontology::Path->new( -identifier     => "16847",
                                           -subject_term   => $subj,
                                           -object_term    => $obj,
                                           -predicate_term => $pred,
                                           -distance       => 3 );


       This is a basic implementation of Bio::Ontology::PathI.

       Essiantially this is a very thin extension of Bio::Ontology::Relationship. It basically
       adds a method distance().


   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.
                  - General discussion  - About the mailing lists

       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.

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

        Title   : new
        Usage   : $rel = Bio::Ontology::Path->new(-identifier   => "16847",
                                                  -subject_term => $subject,
                                                  -object_term  => $object,
                                                  -predicate_term => $type );
                                                  -distance     => 3 );
        Function: Creates a new Bio::Ontology::Path.
        Returns : A new Bio::Ontology::Path object.
        Args    : -identifier     => the identifier of this relationship [scalar]
                  -subject_term   => the subject term [Bio::Ontology::TermI]
                  -object_term    => the object term [Bio::Ontology::TermI]
                  -predicate_term => the predicate term [Bio::Ontology::TermI]
                  -distance       => the distance between subject and object

        Title   : init()
        Usage   : $rel->init();
        Function: Initializes this Path to all undef.
        Returns :
        Args    :

        Title   : distance
        Usage   : $obj->distance($newval)
        Function: Get/set the distance between the two terms connected
                  by this path.

                  Note that modifying the distance may not be meaningful. The
                  implementation here is not connected to any graph engine,
                  so changing an existing value may simply render the
                  attribute's value wrong.

        Example :
        Returns : value of distance (a scalar)
        Args    : on set, new value (a scalar or undef, optional)

        Title   : to_string()
        Usage   : print $rel->to_string();
        Function: to_string method for Path.
        Returns : A string representation of this Path.
        Args    :
