=head1 NAME

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

=head1 SYNOPSIS

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

=head1 DESCRIPTION

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

=head2 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

=head2 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

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