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


version 0.53


    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 );



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 all objects that inherit from it. To use this on a per-case basis, see disable_cycle_check in MooseX::Storage::Basic.

See the SYNOPSIS for a nice example that can be easily cargo-culted.
