NAME
Data::Serializer::Raw - Provides unified raw interface to perl serializers
SYNOPSIS
use Data::Serializer::Raw;
$obj = Data::Serializer::Raw->new();
$obj = Data::Serializer::Raw->new(serializer => 'Storable');
$serialized = $obj->serialize({a => [1,2,3],b => 5});
$deserialized = $obj->deserialize($serialized);
print "$deserialized->{b}\n";
DESCRIPTION
Provides a unified interface to the various serializing modules currently available.
This is a straight pass through to the underlying serializer, nothing else is done. (no encoding, encryption, compression, etc)
EXAMPLES
- Please see Data::Serializer::Cookbook(3)
METHODS
- new - constructor
-
$obj = Data::Serializer::Raw->new(); $obj = Data::Serializer::Raw->new( serializer => 'Data::Dumper', options => {}, );
new is the constructor object for Data::Serializer::Raw objects.
The default serializer is
Data::Dumper
The default options is
{}
(pass nothing on to serializer)
- serialize - serialize reference
-
$serialized = $obj->serialize({a => [1,2,3],b => 5});
This is a straight pass through to the underlying serializer, nothing else is done. (no encoding, encryption, compression, etc)
- deserialize - deserialize reference
-
$deserialized = $obj->deserialize($serialized);
This is a straight pass through to the underlying serializer, nothing else is done. (no encoding, encryption, compression, etc)
- serializer - change the serializer
-
Currently supports the following serializers:
- Bencode(3)
- Convert::Bencode(3)
- Convert::Bencode_XS(3)
- Config::General(3)
- Data::Denter(3)
- Data::Dumper(3)
- Data::Taxi(3)
- FreezeThaw(3)
- JSON(3)
- JSON::Syck(3)
- PHP::Serialization(3)
- Storable(3)
- XML::Dumper(3)
- XML::Simple(3)
- YAML(3)
- YAML::Syck(3)
Default is to use Data::Dumper.
Each serializer has its own caveat's about usage especially when dealing with cyclical data structures or CODE references. Please see the appropriate documentation in those modules for further information.
- options - pass options through to underlying serializer
-
Currently is only supported by Config::General(3), and XML::Dumper(3).
my $obj = Data::Serializer::Raw->new(serializer => 'Config::General', options => { -LowerCaseNames => 1, -UseApacheInclude => 1, -MergeDuplicateBlocks => 1, -AutoTrue => 1, -InterPolateVars => 1 }, ) or die "$!\n"; or my $obj = Data::Serializer::Raw->new(serializer => 'XML::Dumper', options => { dtd => 1, } ) or die "$!\n";
- store - serialize data and write it to a file (or file handle)
-
$obj->store({a => [1,2,3],b => 5},$file, [$mode, $perm]); or $obj->store({a => [1,2,3],b => 5},$fh);
Serializes the reference specified using the serialize method and writes it out to the specified file or filehandle.
If a file path is specified you may specify an optional mode and permission as the next two arguments. See IO::File for examples.
Trips an exception if it is unable to write to the specified file.
- retrieve - read data from file (or file handle) and return it after deserialization
-
my $ref = $obj->retrieve($file); or my $ref = $obj->retrieve($fh);
Reads first line of supplied file or filehandle and returns it deserialized.

ACKNOWLEDGEMENTS
Peter Makholm took the time to profile Data::Serializer(3) and pointed out the value of having a very lean implementation that minimized overhead and just used the raw underlying serializers.
