NAME

Bio::Annotation::AnnotationFactory - Instantiates a new Bio::AnnotationI (or derived class) through a factory

SYNOPSIS

use Bio::Annotation::AnnotationFactory;
# 
my $factory = new Bio::Annotation::AnnotationFactory(
                -type => 'Bio::Annotation::SimpleValue');
my $ann = $factory->create_object(-value => 'peroxisome',
                                  -tagname => 'cellular component');

DESCRIPTION

This object will build Bio::AnnotationI objects generically.

This is mostly copy-and-paste with subsequent adaptation from Bio::Seq::SeqFactory by Jason Stajich. Most credits should in fact go to him.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

new

Title   : new
Usage   : my $obj = new Bio::Annotation::AnnotationFactory();
Function: Builds a new Bio::Annotation::AnnotationFactory object 
Returns : Bio::Annotation::AnnotationFactory
Args    : -type => string, name of a L<Bio::AnnotationI> derived class.

If type is not set the module guesses it based on arguments passed to method create_object.

create_object

Title   : create_object
Usage   : my $seq = $factory->create_object(<named parameters>);
Function: Instantiates new Bio::AnnotationI (or one of its child classes)

          This object allows us to genericize the instantiation of
          cluster objects.

Returns : L<Bio::AnnotationI> compliant object
          The return type is configurable using new(-type =>"...").
Args    : initialization parameters specific to the type of annotation
          object we want.

type

Title   : type
Usage   : $obj->type($newval)
Function: Get/set the type of L<Bio::AnnotationI> object to be created.

          This may be changed at any time during the lifetime of this
          factory.

Returns : value of type
Args    : newvalue (optional)

_guess_type

Title   : _guess_type
Usage   :
Function: Guesses the right type of L<Bio::AnnotationI> implementation
          based on initialization parameters for the prospective
          object.
Example :
Returns : the type (a string, the module name)
Args    : initialization parameters to be passed to the prospective
          cluster object
