Badger::Codec::Chain - encode/decode data using multiple codecs
use Badger::Codec::Chain; # compact form my $codec = Badger::Codec::Chain->new('storable+base64'); # explicit form my $codec = Badger::Codec::Chain->new('storable', 'base64'); # encode/decode data using codec chain my $enc = $codec->encode({ pi => 3.14, e => 2.718 }); my $dec = $codec->decode($encoded);
This module implements a subclass of Badger::Codec which chains together any number of other codec modules.
Constructor method to create a new codec chain. The codecs can be specified by name or as references to Badger::Codec objects.
# by name my $codec = Badger::Codec::Chain->new('storable', 'base64'); # by object reference my $codec = Badger::Codec::Chain->new( Badger::Codec->codec('storable'), Badger::Codec->codec('base64'), );
You can also use the compact form where multiple codec names are separated by +.
+
# compact form my $codec = Badger::Codec::Chain->new('storable+base64');
Encodes the data referenced by the first argument using all the codecs in the chain.
$encoded = $codec->encode($data);
Decodes the encoded data passed as the first argument using all the codecs in the chain in reverse order.
$decoded = $codec->decode($encoded);
Returns a reference to a subroutine which performs the encoding operation.
Returns a reference to a subroutine which performs the decoding operation.
Internal method to construct an encoder or decoder subroutine for a codec chain.
