NAME ^

Bio::Annotation::SimpleValue - A simple scalar

SYNOPSIS ^

   use Bio::Annotation::SimpleValue;
   use Bio::Annotation::Collection;

   my $col = Bio::Annotation::Collection->new();
   my $sv = Bio::Annotation::SimpleValue->new(-value => 'someval');
   $col->add_Annotation('tagname', $sv);

DESCRIPTION ^

Scalar value annotation object

FEEDBACK ^

Mailing Lists

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.

Support

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.

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::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]

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

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.

 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)
