Bio::Annotation::OntologyTerm(3)

NAME
Bio::Annotation::OntologyTerm - An ontology term adapted to AnnotationI

SYNOPSIS
   use Bio::Annotation::OntologyTerm;
   use Bio::Annotation::Collection;
   use Bio::Ontology::Term;

   my $coll = Bio::Annotation::Collection->new();

   # this also implements a tag/value pair, where tag _and_ value are treated
   # as ontology terms
   my $annterm = Bio::Annotation::OntologyTerm->new(-label => 'ABC1',
                                                   -tagname => 'Gene Name');
   # ontology terms can be added directly - they implicitly have a tag
   $coll->add_Annotation($annterm);

   # implementation is by composition - you can get/set the term object
   # e.g.
   my $term = $annterm->term(); # term is-a Bio::Ontology::TermI
   print "ontology term ",$term->name()," (ID ",$term->identifier(),
         "), ontology ",$term->ontology()->name(),"\n";
   $term = Bio::Ontology::Term->new(-name => 'ABC2',
                                    -ontology => 'Gene Name');
   $annterm->term($term);

  Support
Please direct usage questions or support issues to the mailing list:

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

  new
 Title   : new
 Usage   : my $sv = Bio::Annotation::OntologyTerm->new();
 Function: Instantiate a new OntologyTerm object
 Returns : Bio::Annotation::OntologyTerm object
 Args    : -term => $term to initialize the term data field [optional]
           Most named arguments that Bio::Ontology::Term accepts will work
           here too. -label is a synonym for -name, -tagname is a synonym for
           -ontology.

AnnotationI implementing functions

  as_text
 Title   : as_text
 Usage   : my $text = $obj->as_text
 Function: Returns a textual representation of the annotation that
           this object holds. Presently, it is tag name, name of the
           term, and the is_obsolete attribute concatenated togather
           with a delimiter (|).

 Returns : string
 Args    : none

  display_text
 Title   : display_text
 Usage   : my $str = $ann->display_text();
 Function: returns a string. Unlike as_text(), this method returns a string
           formatted as would be expected for te specific implementation.

           One can pass a callback as an argument which allows custom text
           generation; the callback is passed the current instance and any text
           returned
 Example :
 Returns : a string
 Args    : [optional] callback

  hash_tree
 Title   : hash_tree
 Usage   : my $hashtree = $value->hash_tree
 Function: For supporting the AnnotationI interface just returns the value
           as a hashref with the key 'value' pointing to the value
 Returns : hashrf
 Args    : none

  tagname
 Title   : tagname
 Usage   : $obj->tagname($newval)
 Function: Get/set the tagname for this annotation value.

           Setting this is optional. If set, it obviates the need to provide
           a tag to AnnotationCollection when adding this object.

           This is aliased to ontology() here.
 Example :
 Returns : value of tagname (a scalar)
 Args    : new value (a scalar, optional)

Methods for Bio::Ontology::TermI compliance

  term
 Title   : term
 Usage   : $obj->term($newval)
 Function: Get/set the Bio::Ontology::TermI implementing object.

           We implement TermI by composition, and this method sets/gets the
           object we delegate to.
 Example :
 Returns : value of term (a Bio::Ontology::TermI compliant object)
 Args    : new value (a Bio::Ontology::TermI compliant object, optional)

 Returns : The identifier [scalar].
 Args    : The identifier [scalar] (optional).

  name
 Title   : name
 Usage   : $term->name( "N-acetylgalactosaminyltransferase" );
           or
           print $term->name();
 Function: Set/get for the name of this Term.
 Returns : The name [scalar].
 Args    : The name [scalar] (optional).

  definition
 Title   : definition
 Usage   : $term->definition( "Catalysis of ..." );
           or
           print $term->definition();

 Returns : The definition [scalar].
 Args    : The definition [scalar] (optional).

  ontology
 Title   : ontology
 Usage   : $term->ontology( $top );
           or
           $top = $term->ontology();

           another Term (e.g. the top level of the ontology).
 Returns : The ontology of this Term [TermI].
 Args    : The ontology of this Term [TermI or scalar -- which
           becomes the name of the catagory term] (optional).

  is_obsolete
 Title   : is_obsolete
 Usage   : $term->is_obsolete( 1 );
