NAME

MooseX::AutoDestruct - Clear your attributes after a certain time

SYNOPSIS

package Foo;

use Moose;
use namespace::autoclean;
use MooseX::AutoDestruct;

has foo => (
    traits => ['AutoDestruct'],
    is => 'ro', isa => 'Str', lazy_build => 1,
    ttl => 600, # time, in seconds
);

sub _build_foo { --some expensive operation-- }

DESCRIPTION

MooseX::AutoDestruct is an attribute metaclass trait that causes your attribute value to be cleared after a certain time from when the value has been set.

This trait will work regardless of how the value is populated or if a clearer method has been installed; or if the value is accessed via the installed accessors or by accessing the attribute metaclass itself.

TRAITS APPLIED

No traits are automatically applied to any metaclasses; however, on use'ing this package an 'AutoDestruct' attribute trait becomes available.

USAGE

Apply the AutoDestruct trait to your attribute metaclass (e.g. "traits => ['AutoDestruct']") and supply a ttl value.

Typical usage of this could be for an attribute to store a value that is expensive to calculate, and can be counted on to be valid for a certain amount of time (e.g. caching). Builders are your friends :)
