   9 =head1 SYNOPSIS
  10
  11   #
  12   # get a database object somehow using a concrete class
  13   #
  14
  15   $seq = $db->get_Seq_by_id('ROA1_HUMAN');
  16
  17   #
  18   # $seq is a Bio::Seq object

  21 =head1 DESCRIPTION
  22
  23 This is a pure interface class - in other words, all this does is define
  24 methods which other (concrete) classes will actually implement.
  25
  26 The Bio::DB::RandomAccessI class defines what methods a generic database class
  27 should have. At the moment it is just the ability to make Bio::Seq objects
  28 from a name (id) or a accession number.

  40 rather than to the module maintainer directly. Many experienced and
  41 reponsive experts will be able look at the problem and quickly
  42 address it. Please include a thorough description of the problem
  43 with code and data examples if at all possible.

  90  Function: Gets a Bio::Seq object by accession number
  91  Returns : A Bio::Seq object or undef if not found
  92  Args    : accession number (as a string), or a two
  93                element list consisting of namespace=>accession
  94  Throws  : "more than one sequences correspond to this accession"
  95             if the accession maps to multiple primary ids and
  96             method is called in a scalar context
  97
  98 NOTE: The two-element form allows you to choose the namespace for the
  99 accession number.
