Bio::DB::UpdateableSeqI(3)

NAME
Bio::DB::UpdateableSeqI - An interface for writing to a database of sequences.

SYNOPSIS
    # get a Bio::DB::UpdateableSeqI somehow
    eval {
        my ( @updatedseqs, @newseqs, @deadseqs);
        my $seq = $db->get_Seq_by_id('ROA1_HUMAN');
        $seq->desc('a new description');

        push @updatedseqs, $seq;

        $db->write_seq(\@updatedseqs, \@newseqs, \@deadseqs);
    };
    if( $@ ) {
        print STDERR "an error when trying to write seq : $@\n";
    }

DESCRIPTION
This module seeks to provide a simple method for pushing sequence changes back to a Sequence Database - which can be an SQL compliant database, a file based database, AceDB, etc.

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 _

  write_seq
  Title   : write_seq
  Usage   : write_seq(\@updatedseqs, \@addedseqs, \@deadseqs)
  Function: updates sequences in first array,
            adds sequences in the second array,
            and removes sequences in the third array.
  Example :
  Returns :
  Args    : arrays of sequence objects that must be obtained from
            Bio::DB::UpdateableSeqI.

  _add_seq
 Title   : _add_seq
 Usage   : _add_seq($seq)
 Function: Adds a new sequence
 Example :
 Returns : will throw an exception if
           sequences accession number already exists
 Args    : a new seq object - should have an accession number

  _remove_seq
 Title   : _remove_seq
 Usage   : _remove_seq($seq)
 Function: Removes an existing sequence
 Example :
 Returns : will throw an exception if
           sequence does not exists for the primary_id
 Args    : a seq object that was retrieved from Bio::DB::UpdateableSeqI

  _update_seq
 Title   : _update_seq
 Usage   : _update_seq($seq)
 Function: Updates a sequence
 Example :
 Returns : will throw an exception if
           sequence is out of sync from expected val.
 Args    : a seq object that was retrieved from Bio::DB::UpdateableSeqI

Methods inherieted from Bio::DB::RandomAccessI

  get_Seq_by_id
 Title   : get_Seq_by_id
 Usage   : $seq = $db->get_Seq_by_id('ROA1_HUMAN')
 Function: Gets a Bio::Seq object by its name
 Returns : a Bio::Seq object
 Args    : the id (as a string) of a sequence
 Throws  : "id does not exist" exception

  get_Seq_by_acc
 Title   : get_Seq_by_acc
 Usage   : $seq = $db->get_Seq_by_acc('X77802');
 Function: Gets a Bio::Seq object by accession number
 Returns : A Bio::Seq object
 Args    : accession number (as a string)
 Throws  : "acc does not exist" exception

Methods inheirited from Bio::DB::SeqI

  get_PrimarySeq_stream
 Title   : get_PrimarySeq_stream
 Usage   : $stream = get_PrimarySeq_stream
 Function: Makes a Bio::DB::SeqStreamI compliant object
           which provides a single method, next_primary_seq
 Returns : Bio::DB::SeqStreamI
 Args    : none

  get_all_primary_ids
 Title   : get_all_ids
 Usage   : @ids = $seqdb->get_all_primary_ids()
 Function: gives an array of all the primary_ids of the
           sequence objects in the database. These
           maybe ids (display style) or accession numbers
           or something else completely different - they
           *are not* meaningful outside of this database
           implementation.
 Example :
 Returns : an array of strings
 Args    : none

  get_Seq_by_primary_id
 Title   : get_Seq_by_primary_id
 Usage   : $seq = $db->get_Seq_by_primary_id($primary_id_string);
 Function: Gets a Bio::Seq object by the primary id. The primary
           id in these cases has to come from $db->get_all_primary_ids.
           There is no other way to get (or guess) the primary_ids
           in a database.

           The other possibility is to get Bio::PrimarySeqI objects
           via the get_PrimarySeq_stream and the primary_id field
           on these objects are specified as the ids to use here.
 Returns : A Bio::Seq object
 Args    : accession number (as a string)
 Throws  : "acc does not exist" exception
