NAME

Data::HashType - Data object for hash type.

SYNOPSIS

use Data::HashType;

my $obj = Data::HashType->new(%params);
my $id = $obj->id;
my $name = $obj->name;
my $valid_from = $obj->valid_from;
my $valid_to = $obj->valid_to;

DESCRIPTION

The intention of this module is to store information about the usage of digests. Digests are active only within a certain time range, and we need a mechanism to transition to others.

A real-world example is a database table that follows the same format as this data object, with multiple records being valid at different times, while other database tables have relations to this table.

METHODS

new

my $obj = Data::HashType->new(%params);

Constructor.

  • id

    Id of record. Id could be number. It's optional. Default value is undef.

  • name

    Hash type name. Maximal length of value is 50 characters. It's required.

  • valid_from

    Date and time of start of use. Must be a DateTime object. It's required.

  • valid_to

    Date and time of end of use. An undefined value means it is in use. Must be a DateTime object. It's optional.

Returns instance of object.

id

my $id = $obj->id;

Get hash type record id.

Returns number.

name

my $name = $obj->name;

Get hash type name.

Returns string.

valid_from

my $valid_from = $obj->valid_from;

Get date and time of start of use.

Returns DateTime object.

valid_to

my $valid_to = $obj->valid_to;

Get date and time of end of use.

Returns DateTime object or undef.

EXAMPLE

use strict;
use warnings;

use Data::HashType;
use DateTime;

my $obj = Data::HashType->new(
        'id' => 10,
        'name' => 'SHA-256',
        'valid_from' => DateTime->new(
                'year' => 2024,
                'month' => 1,
                'day' => 1,
        ),
);

# Print out.
print 'Name: '.$obj->name."\n";
print 'Id: '.$obj->id."\n";
print 'Valid from: '.$obj->valid_from->ymd."\n";

# Output:
# Name: SHA-256
# Id: 10
# Valid from: 2024-01-01
