14 =head1 NAME
16 Bio::Factory::SequenceStreamI - Interface describing the basics of a Sequence Stream.
18 =head1 SYNOPSIS
20 # get a SequenceStreamI object somehow like with SeqIO
21 use Bio::SeqIO;
22 my $in = Bio::SeqIO->new(-file => '< fastafile');
23 while( my $seq = $in->next_seq ) {
26 =head1 DESCRIPTION
28 This interface is for describing objects which produces
29 Bio::PrimarySeqI objects or processes Bio::PrimarySeqI objects to a
30 data stream.
32 =head1 FEEDBACK
34 =head2 Mailing Lists
36 User feedback is an integral part of the evolution of this and other
37 Bioperl modules. Send your comments and suggestions preferably to
38 the Bioperl mailing list. Your participation is much appreciated.

43 =head2 Support
45 Please direct usage questions or support issues to the mailing list:
47 I<bioperl-l@bioperl.org>
49 rather than to the module maintainer directly. Many experienced and
50 reponsive experts will be able look at the problem and quickly
51 address it. Please include a thorough description of the problem
52 with code and data examples if at all possible.
54 =head2 Reporting Bugs
56 Report bugs to the Bioperl bug tracking system to help us keep track
57 of the bugs and their resolution. Bug reports can be submitted via the
58 web:

66 =head1 APPENDIX
68 The rest of the documentation details each of the object methods.
69 Internal methods are usually preceded with a _

74 # Let the code begin...
77 package Bio::Factory::SequenceStreamI;
78 use strict;
80 use base qw(Bio::Root::RootI);
82 =head2 next_seq
84 Title : next_seq
85 Usage : $seq = stream->next_seq
86 Function: Reads the next sequence object from the stream and returns it.
88 Certain driver modules may encounter entries in the stream that
89 are either misformatted or that use syntax not yet understood
90 by the driver. If such an incident is recoverable, e.g., by
91 dismissing a feature of a feature table or some other non-mandatory
92 part of an entry, the driver will issue a warning. In the case
93 of a non-recoverable situation an exception will be thrown.
94 Do not assume that you can resume parsing the same stream after
95 catching the exception. Note that you can always turn recoverable
96 errors into exceptions by calling $stream->verbose(2).
97 Returns : a Bio::Seq sequence object
98 Args : none

108 =head2 write_seq
110 Title : write_seq
111 Usage : $stream->write_seq($seq)
112 Function: writes the $seq object into the stream
113 Returns : 1 for success and 0 for error

125 Usage : $seqio->sequence_factory($seqfactory)
126 Function: Get the Bio::Factory::SequenceFactoryI
