NAME
Tie::File::Indexed::Storable - tied array access to indexed data files: Storable-encoded references (native byte-order)
SYNOPSIS
use Tie::File::Indexed::Storable;
tie(my @data, 'Tie::File::Indexed::Storable', $filename, %options) or die ...
##-- add some data
$data[0] = {foo=>'bar'}; # transparently encode/decode perl hashes
$data[1] = [1..10]; # ... or arrays
$data[2] = \42; # ... or scalar-refs
$data[3] = undef; # ... or undef
print $data[1]; # retrieve & print a stored value
DESCRIPTION
Tie::File::Indexed::Storable provides a Tie::File::Indexed subclass for storing arrays of perl data structures encoded using the Storable module. Data items are written in the native byte-order using Storable::store_fd().
See "SUBCLASSES" in Tie::File::Indexed for an overview of the built-in Tie::File::Indexed subclasses.
CAVEATS
General caveats
See "CAVEATS" in Tie::File::Indexed for general issues regarding the Tie::File::Indexed base class.
In-place item modification not supported
See "In-place item modification not supported" in Tie::File::Indexed::JSON for details.
Limited datatype support
Only references which can be successfully encoded and decoded by the Storable module are supported by this class. In particlar, that means that you can't store raw SCALARs or CODE refs without further ado, although you CAN store undef
values, which Storable also doesn't support. The Storable module itself provides additional hooks for serialization of bless()ed object, see Storable for details.
