NAME

6       Throwable - a role for classes that can be thrown
7

VERSION

9       version 0.200013

SYNOPSIS

12         package Redirect;
13         # NOTE: Moo can also be used here instead of Moose
14         use Moose;
15         with 'Throwable';
16
17         has url => (is => 'ro');
18
19       ...then later...
20
21         Redirect->throw({ url => $url });
22

DESCRIPTION

24       Throwable is a role for classes that are meant to be thrown as
25       exceptions to standard program flow.  It is very simple and does only
26       two things: saves any previous value for $@ and calls "die $self".
27
28       Throwable is implemented with Moo, so you can stick to Moo or use
29       Moose, as you prefer.

ATTRIBUTES

32   previous_exception
33       This attribute is created automatically, and stores the value of $@
34       when the Throwable object is created.  This is done on a best effort
35       basis.  $@ is subject to lots of spooky action-at-a-distance.  For now,
36       there are clearly ways that the previous exception could be lost.
37

METHODS

39   throw
40         Something::Throwable->throw({ attr => $value });
41
42       This method will call new, passing all arguments along to new, and will
43       then use the created object as the only argument to "die".
44
45       If called on an object that does Throwable, the object will be
46       rethrown.
