=head1 DESCRIPTION |
63
|
|
|
|
|
|
|
|
64
|
|
|
|
|
|
|
This validator allows checking against a CodeRef. The CodeRef will be getting |
65
|
|
|
|
|
|
|
all parameters on B<@_> as Hash, and the specific parameter value for to check |
66
|
|
|
|
|
|
|
against will be in B<$_>, so the coderef can decide which way he want to check. |
67
|
|
|
|
|
|
|
|
68
|
|
|
|
|
|
|
The CodeRef should give back nothing (not even B<undef>) if its a success. Else |
69
|
|
|
|
|
|
|
if should give back B<undef> to release the error message given on L</message> |
70
|
|
|
|
|
|
|
or the default error message B<'Your value for %s is not valid.'>. Alternative |
71
|
|
|
|
|
|
|
it can also give back a string which will be used as B<message> for the error. |
