NAME

Data::Login - Data object for login.

SYNOPSIS

use Data::Login;

my $obj = Data::Login->new(%params);
my $hash_type = $obj->hash_type;
my $id = $obj->id;
my $login_name = $obj->login_name;
my $password_hash = $obj->password_hash;
my $roles_ar = $obj->roles;
my $valid_from = $obj->valid_from;
my $valid_to = $obj->valid_to;

DESCRIPTION

The intention of this module is to store information about the user logins. User logins 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, e.g. for transfering of Digest from obsolete version to new. Or planning of access to system from concrete date.

METHODS

new

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

Constructor.

  • hash_type

    Hash type object. Possible value is Data::HashType object. Parameter is required. Default value is undef.

  • id

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

  • login_name

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

  • password_hash

    Password hash. Maximal length of value is 128 characters. It's required.

  • roles

    Login roles list. Possible value is reference to array with Data::Login::Role objects. Parameter is optional. Default value is [].

  • 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.

hash_type

my $hash_type = $obj->hash_type;

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.
