Badger::Codec::Timestamp

NAME

Top Close Open

Badger::Codec::Timestamp - encode/decode a timestamp via Badger::Timestamp

SYNOPSIS

Top Close Open
use Badger::Codec::Timestamp;
use Badger::Timestamp 'Now';

my $codec   = Badger::Codec::Timestamp->new();
my $encoded = $codec->encode(Now);
my $decoded = $codec->decode($encoded);

DESCRIPTION

Top Close Open

This module implements a subclass of Badger::Codec for encoded and decoding timestamps using the Badger::Timestamp module. It is trivially simple, existing only to provide a consistent API with other Badger::Codec modules. It is typically used as a codec for reading and writing timestamps to and from a file via the Badger::Filesystem modules.

use Badger::Filesystem 'File';
use Badger::Timestamp 'Now';

my $stamp = Now;                     # current data/time
my $file  = File(
    'example.ts',                   # filename
    { codec => 'timestamp' }        # specify timestamp codec
);

# write timestamp to file
$file->data($stamp);

# read timestamp from file
$stamp = $file->data;

METHODS

Top Close Open

encode($timestamp)

Top Close Open

Encodes the timestamp passed as an argument. The argument can be a Badger::Timestamp object or any of the constructor parameters accepted by Badger::Timestamp. The following example demonstrates how this works in principle, although it should be noted that it's completely pointless in practice. It is sufficient to simply call Now->timestamp to serialise a Badger::Timestamp to text without the need for any codec module (in fact, that's all the encode() method does behind the scenes).

use Badger::Timestamp 'Now';
$encoded = Badger::Codec::Timestamp->encode(Now);

decode($data)

Top Close Open

Decodes the encoded timestamp passed as the first argument. Returns a Badger::Timestamp object.
