User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via the web:

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : new
Usage : my $sv = Bio::Annotation::SimpleValue->new();
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]
Title : as_text Usage : my $text = $obj->as_text Function: return the string "Value: $v" where $v is the value Returns : string Args : none
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
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
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)
Title : value Usage : $obj->value($newval) Function: Get/Set the value for simplevalue Returns : value of value Args : newvalue (optional)
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)
