MooseX::Storage::Engine::Trait::DisableCycleDetection - A custom trait to bypass cycle detection

SYNOPSIS

Top

    package Double;
    use Moose;
    use MooseX::Storage;
    with Storage( traits => ['DisableCycleDetection'] );

    has 'x' => ( is => 'rw', isa => 'HashRef' );
    has 'y' => ( is => 'rw', isa => 'HashRef' );

    my $ref = {};

    my $double = Double->new( 'x' => $ref, 'y' => $ref );

    $double->pack;

DESCRIPTION

Top

MooseX::Storage implements a primitive check for circular references. This check also triggers on simple cases as shown in the Synopsis. Providing the DisableCycleDetection traits disables checks for any cyclical references, so if you know what you are doing, you can bypass this check.

This trait is applied to an instance of MooseX::Storage::Engine, for the user-visible version shown in the SYNOPSIS, see MooseX::Storage::Traits::DisableCycleDetection
