Badger::Codec::JSON - encode/decode data using JSON

SYNOPSIS

Top

    use Badger::Codec::JSON;
    my $codec   = Badger::Codec::JSON->new();
    my $encoded = $codec->encode({ msg => "Hello World" });
    my $decoded = $codec->decode($encoded);

DESCRIPTION

Top

This module implements a subclass of Badger::Codec which uses the JSON::XS or JSON module (whichever you have installed) to encode and decode data to and from JSON. It is little more than an adapter module to fit JSON into the Badger::Codec mould.

METHODS

Top

encode($data)

Encodes the Perl data in $data to a JSON string. This method is a wrapper around the internal the encode_json() subroutine.

    $encoded = Badger::Codec::JSON->encode($data);   

decode($json)

Decodes the encoded JSON string in $json back into a Perl data structure. This method is a wrapper around the internal the decode_json() subroutine.

    $decoded = Badger::Codec::JSON->decode($encoded);

encoder()

This method returns a reference to the real subroutine that's doing all the encoding work, i.e. the internal encode_json() subroutine.

decoder()

This method returns a reference to the real subroutine that's doing all the decoding work, i.e. the decode_json() subroutine in JSON.

INTERNAL SUBROUTINES

Top

encode_json($data)

This is the internal subroutine that encodes the JSON data. It delegates to the JSON::XS or JSON module, depending on which you have installed.

decode_json($json)

This is the internal subroutine that decodes the JSON data. As per encode_json(), it delegates the task to the JSON::XS or JSON module.
