# compact form

# explicit form

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);
