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

METHODS

  $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)
  $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)

  $deserialized = $obj->deserialize($serialized);
    

This is a straight pass through to the underlying serializer, nothing else is done. (no encoding, encryption, compression, etc)

Currently supports the following serializers:

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.

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";
    
  $obj->store({a => [1,2,3],b => 5},$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.

  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.
