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.
