=head1 NAME
Bio::Annotation::OntologyTerm - An ontology term adapted to AnnotationI
=head1 SYNOPSIS
use Bio::Annotation::OntologyTerm;
use Bio::Annotation::Collection;
use Bio::Ontology::Term;
my $coll = new Bio::Annotation::Collection;
# this also implements a tag/value pair, where tag _and_ value are treated
# as ontology terms
my $annterm = new Bio::Annotation::OntologyTerm(-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);

=head2 new
Title : new
Usage : my $sv = new Bio::Annotation::OntologyTerm;
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.

=head1 AnnotationI implementing functions
=cut
=head2 as_text
Title : as_text
Usage : my $text = $obj->as_text
Function: return the string "Name: $v" where $v is the name of the term
Returns : string
Args : none
=cut
sub as_text{
my ($self) = @_;
return $self->tagname()."|".$self->name()."|".$self->identifier();
}
=head2 hash_tree
Title : hash_tree
Usage : my $hashtree = $value->hash_tree
Function: For supporting the AnnotationI interface just returns the value
as a hashref with the key 'value' pointing to the value
Returns : hashrf
Args : none
=cut
sub hash_tree{
my ($self) = @_;
my $h = {};
$h->{'name'} = $self->name();
$h->{'identifier'} = $self->identifier();

$h->{'synonyms'} = [$self->each_synonym()];
}
=head2 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)
=cut
sub tagname{
my $self = shift;
return $self->ontology(@_) if @_;
# if in get mode we need to get the name from the ontology
my $ont = $self->ontology();
return ref($ont) ? $ont->name() : $ont;
}
=head1 Methods for Bio::Ontology::TermI compliance
=cut
=head2 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)
=cut
sub term{
my ($self,$value) = @_;
if( defined $value) {
$self->{'term'} = $value;
}
if(! exists($self->{'term'})) {
$self->{'term'} = Bio::Ontology::Term->new();
}
return $self->{'term'};
}
