Throwable(3) a role for classes that can be thrown

VERSION

version 0.200013

SYNOPSIS


package Redirect;
# NOTE: Moo can also be used here instead of Moose
use Moose;
with 'Throwable';
has url => (is => 'ro');

...then later...

  Redirect->throw({ url => $url });

DESCRIPTION

Throwable is a role for classes that are meant to be thrown as exceptions to standard program flow. It is very simple and does only two things: saves any previous value for [email protected] and calls "die $self".

Throwable is implemented with Moo, so you can stick to Moo or use Moose, as you prefer.

ATTRIBUTES

previous_exception

This attribute is created automatically, and stores the value of [email protected] when the Throwable object is created. This is done on a best effort basis. [email protected] is subject to lots of spooky action-at-a-distance. For now, there are clearly ways that the previous exception could be lost.

METHODS

throw

  Something::Throwable->throw({ attr => $value });

This method will call new, passing all arguments along to new, and will then use the created object as the only argument to "die".

If called on an object that does Throwable, the object will be rethrown.
