NAME

CDB_File_Thawed - Storable thaw() values in a CDB_File

SYNOPSIS

  # to create a CDB file:
  my $cdb = CDB_File_Thawed->new($filename, $tempfile) or die $!;
  $cdb->insert($key1, $value1);
  $cdb->insert($key2, $value2);
  $cdb->finish;

  # to use a CDB file:
  tie my %cdb, 'CDB_File_Thawed', $filename2 or die "tie failed: $!\n";
  # use %cdb has a normal (but read-only) hash
  

DESCRIPTION

This module is a small wrapper around CDB_File which makes sure to use Storable's nfreeze() and thaw() methods to store values. CDB_File is an interface to Dan Berstein's Constant DataBase library, which as the name implies is a fast, reliable, simple package for creating and reading constant databases. Using this module you can store Perl data structures and objects in a fast CDB_File.

METHODS
