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().

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 email or the web: bioperl-bugs@bio.perl.org http://bugzilla.bioperl.org/ Hilmar Lapp <hlapp@gmx.net> The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

new
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

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

distance
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)

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