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

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
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 | Top |
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
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
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
