Bio::SeqIO::swissdriver(3)

NAME
Bio::SeqIO::swissdriver - SwissProt/UniProt handler-based push parser

SYNOPSIS
  #It is probably best not to use this object directly, but
  #rather go through the SeqIO handler:

  $stream = Bio::SeqIO->new(-file => $filename,
                            -format => 'swissdriver');

  while ( my $seq = $stream->next_seq() ) {
      # do something with $seq
  }

DESCRIPTION
This object can transform Bio::Seq objects to and from UniProt flat file databases. The key difference between this parser and the tried-and-true Bio::SeqIO::swiss parser is this version separates the parsing and data manipulation into a 'driver' method (next_seq) and separate object handlers which deal with the data passed to it.

  The Driver
The main purpose of the driver routine, in this case next_seq(), is to carve out the data into meaningful chunks which are passed along to relevant handlers (see below).

Each chunk of data in the has a NAME tag attached to it, similar to that for XML parsing. This designates the type of data passed (annotation type or seqfeature) and the handler to be called for processing the data.

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 _

  next_seq
 Title   : next_seq
 Usage   : $seq = $stream->next_seq()
 Function: returns the next sequence in the stream
 Returns : Bio::Seq object
 Args    : none

  write_seq
 Title   : write_seq
 Usage   : $stream->write_seq($seq)
 Function: writes the $seq object (must be seq) to the stream
 Returns : 1 for success and 0 for error
 Args    : array of 1 to n Bio::SeqI objects

  seqhandler
 Title   : seqhandler
 Usage   : $stream->seqhandler($handler)
 Function: Get/Set the Bio::Seq::HandlerBaseI object
 Returns : Bio::Seq::HandlerBaseI
 Args    : Bio::Seq::HandlerBaseI
