13 |  |  |  |  |
14 |  |  |  |  | DBIx::Class::Exception - Exception objects for DBIx::Class
15 |  |  |  |  |
16 |  |  |  |  | =head1 DESCRIPTION
17 |  |  |  |  |
18 |  |  |  |  | Exception objects of this class are used internally by
19 |  |  |  |  | the default error handling of L<DBIx::Class::Schema/throw_exception>
20 |  |  |  |  | and derivatives.
21 |  |  |  |  |
22 |  |  |  |  | These objects stringify to the contained error message, and use
23 |  |  |  |  | overload fallback to give natural boolean/numeric values.
24 |  |  |  |  |

34 |  |  |  |  |
35 |  |  |  |  | This is meant for internal use by L<DBIx::Class>'s C<throw_exception>
36 |  |  |  |  | code, and shouldn't be used directly elsewhere.
37 |  |  |  |  |
38 |  |  |  |  | Expects a scalar exception message. The optional argument
39 |  |  |  |  | C<$stacktrace> tells it to output a full trace similar to L<Carp/confess>.
