moosex::setonce
MooseX::SetOnce(3pm) User Contributed Perl Documentation MooseX::SetOnce(3pm)
NAME
MooseX::SetOnce - write-once, read-many attributes for Moose
VERSION
version 0.200001
SYNOPSIS
Add the "SetOnce" trait to attributes:
package Class;
use Moose;
use MooseX::SetOnce;
has some_attr => (
is => 'rw',
traits => [ qw(SetOnce) ],
);
...and then you can only set them once:
my $object = Class->new;
$object->some_attr(10); # works fine
$object->some_attr(20); # throws an exception: it's already set!
DESCRIPTION
The 'SetOnce' attribute lets your class have attributes that are not lazy and not set, but that cannot be altered once set.
The logic is very simple: if you try to alter the value of an attribute with the SetOnce trait, either by accessor or writer, and the
attribute has a value, it will throw an exception.
If the attribute has a clearer, you may clear the attribute and set it again.
