NAME

Venus::Sealed - Sealed Class

ABSTRACT

Sealed Class for Perl 5

SYNOPSIS

package main;

use Venus::Sealed;

my $sealed = Venus::Sealed->new('012345');

# $sealed->get;

# '012345'

DESCRIPTION

This package provides a mechanism for sealing object and restricting and/or preventing access to the underlying data structures. This package can be used directly but is meant to be subclassed.

INTEGRATES

This package integrates behaviors from:

Venus::Role::Buildable

Venus::Role::Catchable

Venus::Role::Proxyable

Venus::Role::Throwable

Venus::Role::Tryable

METHODS

This package provides the following methods:

get

get(any @args) (any)

The get method can be used directly to get the sealed value set during instantiation, but is meant to be overridden in a subclass to further control access to the underlying data.

Since 3.55

get example 1
# given: synopsis

package main;

my $get = $sealed->get;

# "012345"
get example 2
package Example;

use Venus::Class;

base 'Venus::Sealed';

sub __get {
  my ($self, $init, $data) = @_;

  return $data->{value};
}

sub __set {
  my ($self, $init, $data, $value) = @_;

  return $data->{value} = $value;
}

package main;

my $sealed = Example->new("012345");

my $get = $sealed->get;

# "012345"

set

set(any @args) (any)

The set method can be used directly to set the sealed value set during instantiation, but is meant to be overridden in a subclass to further control access to the underlying data.

Since 3.55

# given: synopsis

package main;

my $set = $sealed->set("098765");

# "098765"
set example 2
package Example;

use Venus::Class;

base 'Venus::Sealed';

sub __get {
  my ($self, $init, $data) = @_;

  return $data->{value};
}

sub __set {
  my ($self, $init, $data, $value) = @_;

  return $data->{value} = $value;
