NAME

MooX::Keyword::Readonly - Truly readonly attributes

VERSION

Version 1.00

SYNOPSIS

package Abc;

use Moo;
use MooX::Keyword extends => '+Readonly';

readonly "array";

readonly hash => ( is => 'rw' );

...

my $abc = Abc->new({ array => [1, 2, 3], hash => { a => 1, b => 2, c => 3 }});

push @{ $abc->array }, 4; # dies as array is a readonly array
$abc->hash->{d}; # dies as hash is a readonly hash with restricted keys

If you just want radonly attributes you are probably looking at the wrong module, MooX::Readonly::Attribute works more transparently unless you are already using MooX::Keyword.

KEYWORDS

readonly

Creates a truly read only attribute.

readonly "array";

The behaviour is identical to the following Moo code.

use Const::XS qw/make_readonly/;

has array => (
	is => 'ro',
	coerce => sub { make_readonly($_[0]); $_[0] }
);
