Bio::Factory::SequenceStreamI(3)

NAME
Bio::Factory::SequenceStreamI - Interface describing the basics of a Sequence Stream.

SYNOPSIS
  # get a SequenceStreamI object somehow like with SeqIO
  use Bio::SeqIO;
  my $in = Bio::SeqIO->new(-file => '< fastafile');
  while( my $seq = $in->next_seq ) {
  }

DESCRIPTION
This interface is for describing objects which produces Bio::PrimarySeqI objects or processes Bio::PrimarySeqI objects to a data stream.

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 the Bioperl mailing list. 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: Reads the next sequence object from the stream and returns it.

           Certain driver modules may encounter entries in the stream that
           are either misformatted or that use syntax not yet understood
           by the driver. If such an incident is recoverable, e.g., by
           dismissing a feature of a feature table or some other non-mandatory
           part of an entry, the driver will issue a warning. In the case
           of a non-recoverable situation an exception will be thrown.
           Do not assume that you can resume parsing the same stream after
           catching the exception. Note that you can always turn recoverable
           errors into exceptions by calling $stream->verbose(2).
 Returns : a Bio::Seq sequence object
 Args    : none

See Bio::Root::RootI

  write_seq
 Title   : write_seq
 Usage   : $stream->write_seq($seq)
 Function: writes the $seq object into the stream
 Returns : 1 for success and 0 for error
 Args    : Bio::Seq object

  sequence_factory
 Title   : sequence_factory
 Usage   : $seqio->sequence_factory($seqfactory)
 Function: Get the Bio::Factory::SequenceFactoryI
 Returns : Bio::Factory::SequenceFactoryI
 Args    : none
