=head1 DESCRIPTION |
75
|
|
|
|
|
|
|
|
76
|
|
|
|
|
|
|
Please first see L<Syccess::Validator>. This role is a wrapper around it, |
77
|
|
|
|
|
|
|
which requires a function B<validator>, which will be called with the value |
78
|
|
|
|
|
|
|
given on the parameters for the field where the validator is used. By default, |
79
|
|
|
|
|
|
|
it ignores a not existing value, an undefined value or an empty string. You |
80
|
|
|
|
|
|
|
can override this behaviour by overloading the functions B<missing_ok>, |
81
|
|
|
|
|
|
|
B<undef_ok> or B<empty_ok> with a sub that returns a false value. Then this |
82
|
|
|
|
|
|
|
specific case will still be dispatched to the B<validator> function and can |
83
|
|
|
|
|
|
|
then there produce an error, or not ;). |
84
|
|
|
|
|
|
|
|
85
|
|
|
|
|
|
|
If the value is missing, then B<@_> will only contain a reference to the |
86
|
|
|
|
|
|
|
validator object, but no value itself (if you override B<missing_ok>). |
