Methods description
Title : new
Usage : $term = Bio::Ontology::Term->new( -identifier => "16847",
-name => "1-aminocyclopropane-1-carboxylate synthase",
-definition => "Catalysis of ...",
-is_obsolete => 0,
-comment => "" );
Function: Creates a new Bio::Ontology::Term.
Returns : A new Bio::Ontology::Term object.
Args : -identifier => the identifier of this term [scalar]
-name => the name of this term [scalar]
-definition => the definition of this term [scalar]
-ontology => the ontology this term lives in
(a Bio::Ontology::OntologyI object)
-version => version information [scalar]
-is_obsolete => the obsoleteness of this term [0 or 1]
-comment => a comment [scalar] |
Title : identifier
Usage : $term->identifier( "0003947" );
or
print $term->identifier();
Function: Set/get for the identifier of this Term.
Returns : The identifier [scalar].
Args : The identifier [scalar] (optional). |
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). |
Title : definition
Usage : $term->definition( "Catalysis of ..." );
or
print $term->definition();
Function: Set/get for the definition of this Term.
Returns : The definition [scalar].
Args : The definition [scalar] (optional). |
Title : ontology
Usage : $ont = $term->ontology();
or
$term->ontology( $ont );
Function: Get the ontology this term is in.
Note that with the ontology in hand you can query for all
related terms etc. See Bio::Ontology::OntologyI.
Returns : The ontology of this Term as a Bio::Ontology::OntologyI
implementing object.
Args : On set, the ontology of this Term as a Bio::Ontology::OntologyI
implementing object or a string representing its name. |
Title : version
Usage : $term->version( "1.00" );
or
print $term->version();
Function: Set/get for version information.
Returns : The version [scalar].
Args : The version [scalar] (optional). |
Title : is_obsolete
Usage : $term->is_obsolete( 1 );
or
if ( $term->is_obsolete() )
Function: Set/get for the obsoleteness of this Term.
Returns : the obsoleteness [0 or 1].
Args : the obsoleteness [0 or 1] (optional). |
Title : comment
Usage : $term->comment( "Consider the term ..." );
or
print $term->comment();
Function: Set/get for an arbitrary comment about this Term.
Returns : A comment.
Args : A comment (optional). |
Title : get_synonyms
Usage : @aliases = $term->get_synonyms;
Function: Returns a list of aliases of this Term.
Returns : A list of aliases [array of [scalar]].
Args : |
Title : add_synonym
Usage : $term->add_synonym( @asynonyms );
or
$term->add_synonym( $synonym );
Function: Pushes one or more synonyms into the list of synonyms.
Returns :
Args : One synonym [scalar] or a list of synonyms [array of [scalar]]. |
Title : remove_synonyms()
Usage : $term->remove_synonyms();
Function: Deletes (and returns) the synonyms of this Term.
Returns : A list of synonyms [array of [scalar]].
Args : |
Title : get_dblinks()
Usage : @ds = $term->get_dblinks();
Function: Returns a list of each dblinks of this GO term.
Returns : A list of dblinks [array of [scalars]].
Args : |
Title : add_dblink
Usage : $term->add_dblink( @dbls );
or
$term->add_dblink( $dbl );
Function: Pushes one or more dblinks onto the list of dblinks.
Returns :
Args : One dblink [scalar] or a list of
dblinks [array of [scalars]]. |
Title : remove_dblinks()
Usage : $term->remove_dblinks();
Function: Deletes (and returns) the definition references of this GO term.
Returns : A list of definition references [array of [scalars]].
Args : |
Title : get_secondary_ids
Usage : @ids = $term->get_secondary_ids();
Function: Returns a list of secondary identifiers of this Term.
Secondary identifiers mostly originate from merging terms,
or possibly also from splitting terms.
Returns : A list of secondary identifiers [array of [scalar]]
Args : |
Title : add_secondary_id
Usage : $term->add_secondary_id( @ids );
or
$term->add_secondary_id( $id );
Function: Adds one or more secondary identifiers to this term.
Returns :
Args : One or more secondary identifiers [scalars] |
Title : remove_secondary_ids
Usage : $term->remove_secondary_ids();
Function: Deletes (and returns) the secondary identifiers of this Term.
Returns : The previous list of secondary identifiers [array of [scalars]]
Args : |
Title : object_id
Usage : $string = $obj->object_id()
Function: a string which represents the stable primary identifier
in this namespace of this object.
This is a synonym for identifier().
Returns : A scalar |
Title : authority
Usage : $authority = $obj->authority()
Function: a string which represents the organisation which
granted the namespace, written as the DNS name for
organisation (eg, wormbase.org)
This forwards to ontology()->authority(). Note that you
cannot set the authority before having set the ontology or
the namespace (which will set the ontology).
Returns : A scalar
Args : on set, the new value (a scalar) |
Title : namespace
Usage : $string = $obj->namespace()
Function: A string representing the name space this identifier
is valid in, often the database name or the name
describing the collection.
This forwards to ontology() (set mode) and
ontology()->name() (get mode). I.e., setting the namespace
will set the ontology to one matching that name in the
ontology store, or to one newly created.
Returns : A scalar
Args : on set, the new value (a scalar) |
Title : display_name
Usage : $string = $obj->display_name()
Function: A string which is what should be displayed to the user.
The definition in Bio::DescribableI states that the
string should not contain spaces. As this isn't very
sensible for ontology terms, we relax this here. The
implementation just forwards to name().
Returns : A scalar
Args : on set, the new value (a scalar) |
Title : description
Usage : $string = $obj->description()
Function: A text string suitable for displaying to the user a
description. This string is likely to have spaces, but
should not have any newlines or formatting - just plain
text.
This forwards to definition(). The caveat is that the text
will often be longer for ontology term definitions than the
255 characters stated in the definition in
Bio::DescribableI.
Returns : A scalar
Args : on set, the new value (a scalar) |
Title : category
Usage :
Function: This method is deprecated. Use ontology() instead.
Example :
Returns :
Args : |
