Bio::SeqIO::swissdriver - SwissProt/UniProt handler-based push parser
#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
}
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 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.

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.

The rest of the documentation details each of the object methods. Internal
methods are usually preceded with a _
Title : next_seq
Usage : $seq = $stream->next_seq()
Function: returns the next sequence in the stream
Returns : Bio::Seq object
Args : none
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
Title : seqhandler
Usage : $stream->seqhandler($handler)
Function: Get/Set the Bio::Seq::HandlerBaseI object
Returns : Bio::Seq::HandlerBaseI
Args : Bio::Seq::HandlerBaseI
