Summary

Bio::Seq::SeqFactory - Instantiates a new Bio::PrimarySeqI (or derived class) through a factory

Package variables

Included modules

Inherit

Bio::Factory::SequenceFactoryI Bio::Root::Root

Synopsis

    use Bio::Seq::SeqFactory;
    my $factory = new Bio::Seq::SeqFactory;
    my $seq = $factory->create(-seq => 'WYRAVLC',
			       -id  => 'name');

    # If you want the factory to create Bio::Seq objects instead
    # of the default Bio::PrimarySeq objects, use the -type parameter:

    my $factory = new Bio::Seq::SeqFactory(-type => 'Bio::Seq');

Description

This object will build Bio::PrimarySeqI and Bio::SeqI objects
generically.

Methods

Methods description

 Title   : create
 Usage   : my $seq = $seqbuilder->create(-seq => 'CAGT', -id => 'name');
 Function: Instantiates new Bio::SeqI (or one of its child classes)
           This object allows us to genericize the instantiation of sequence
           objects.
 Returns : Bio::PrimarySeq object (default)
           The return type is configurable using new(-type =>"...").
 Args    : initialization parameters specific to the type of sequence
           object we want.  Typically 
           -seq        => $str,
           -display_id => $name

 Title   : new
 Usage   : my $obj = new Bio::Seq::SeqFactory();
 Function: Builds a new Bio::Seq::SeqFactory object 
 Returns : Bio::Seq::SeqFactory
 Args    : -type => string, name of a PrimarySeqI derived class
                    This is optional. Default=Bio::PrimarySeq.

 Title   : type
 Usage   : $obj->type($newval)
 Function: 
 Returns : value of type
 Args    : newvalue (optional)

	       $a->isa('Bio::Seq::QualI') ) {
	   $self->throw("Must provide a valid Bio::PrimarySeqI or Bio::Seq::QualI or child class to SeqFactory Not $value");
       }
      $self->{'type'} = $value;
    }
