Tie::File::Indexed::FreezeN - tied array access to indexed data files: Storable::nfreeze()-encoded references (network byte-order)


 use Tie::File::Indexed::FreezeN;
 tie(my @data, 'Tie::File::Indexed::FreezeN', $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


Tie::File::Indexed::Freeze provides a Tie::File::Indexed subclass for storing arrays of perl data structures encoded using the Storable module. Data items are written in the "network" byte-order using Storable::nfreeze().

See "SUBCLASSES" in Tie::File::Indexed for an overview of the built-in Tie::File::Indexed subclasses.
