NAME

       Bio::DB::InMemoryCache - Abstract interface for a sequence database

SYNOPSIS

         $cachedb = Bio::DB::InMemoryCache->new( -seqdb => $real_db,
                                                 -number => 1000);
         #
         # get a database object somehow using a concrete class
         #

         $seq = $cachedb->get_Seq_by_id('ROA1_HUMAN');

         #
         # $seq is a Bio::Seq object
         #

DESCRIPTION

       This is a memory cache system which saves the objects returned by Bio::DB::RandomAccessI
       in memory to a hard limit of sequences.

   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.

   Reporting Bugs

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
        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

   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
