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.

Support

Please direct usage questions or support issues to the mailing list:

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
