SYNOPSIS
#
# get a database object somehow using a concrete class
#
$seq = $db->get_Seq_by_id('ROA1_HUMAN');
#
# $seq is a Bio::Seq object
#
DESCRIPTION
This is a pure interface class - in other words, all this does is
define methods which other (concrete) classes will actually implement.
The Bio::DB::RandomAccessI class defines what methods a generic
database class should have. At the moment it is just the ability to
make Bio::Seq objects from a name (id) or a accession number.

Support
Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
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 _
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 or undef if not found
Args : the id (as a string) of a sequence,
get_Seq_by_acc
Title : get_Seq_by_acc
Usage : $seq = $db->get_Seq_by_acc('X77802');
$seq = $db->get_Seq_by_acc(Locus => 'X77802');
Function: Gets a Bio::Seq object by accession number
Returns : A Bio::Seq object or undef if not found
Args : accession number (as a string), or a two
element list consisting of namespace=>accession
Throws : "more than one sequences correspond to this accession"
if the accession maps to multiple primary ids and
method is called in a scalar context
NOTE: The two-element form allows you to choose the namespace for the
accession number.
get_Seq_by_version
Title : get_Seq_by_version
Usage : $seq = $db->get_Seq_by_version('X77802.1');
Function: Gets a Bio::Seq object by sequence version
Returns : A Bio::Seq object
Args : accession.version (as a string)
Throws : "acc.version does not exist" exception
