Bio::DB::Failover - A Bio::DB::RandomAccessI compliant class which wraps a prioritized list of DBs
$failover = Bio::DB::Failover->new(); $failover->add_database($db); # fail over Bio::DB::RandomAccessI.pm # this will check each database in priority, returning when # the first one succeeds $seq = $failover->get_Seq_by_id($id);
This module provides fail over access to a set of Bio::DB::RandomAccessI objects.

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 : "no id" exception
Title : get_Seq_by_version Usage : $seq = $db->get_Seq_by_acc('X77802.2'); Function: Gets a Bio::Seq object by versioned accession number Returns : A Bio::Seq object Args : accession number (as a string) Throws : "acc does not exist" exception
