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 = new Bio::Annotation::SimpleValue;
Function: Instantiate a new SimpleValue object
Returns : Bio::Annotation::SimpleValue object
Args    : -value    => $value to initialize the object data field [optional]
          -tagname  => $tag to initialize the tagname [optional]
          -tag_term => ontology term representation of the tag [optional]

AnnotationI implementing functions

as_text

Title   : as_text
Usage   : my $text = $obj->as_text
Function: return the string "Value: $v" where $v is the value
Returns : string
Args    : none

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.

Example :
Returns : value of tagname (a scalar)
Args    : new value (a scalar, optional)

Specific accessors for SimpleValue

value

Title   : value
Usage   : $obj->value($newval)
Function: Get/Set the value for simplevalue
Returns : value of value
Args    : newvalue (optional)

tag_term

Title   : tag_term
Usage   : $obj->tag_term($newval)
Function: Get/set the L<Bio::Ontology::TermI> object representing
          the tag name.

          This is so you can specifically relate the tag of this
          annotation to an entry in an ontology. You may want to do
          this to associate an identifier with the tag, or a
          particular category, such that you can better match the tag
          against a controlled vocabulary.

          This accessor will return undef if it has never been set
          before in order to allow this annotation to stay
          light-weight if an ontology term representation of the tag
          is not needed. Once it is set to a valid value, tagname()
          will actually delegate to the name() of this term.

Example :
Returns : a L<Bio::Ontology::TermI> compliant object, or undef
Args    : on set, new value (a L<Bio::Ontology::TermI> compliant
          object or undef, optional)
