sub validate {
my $self = shift;
my ($proto, $field, $param) = @_;
if (defined $field->{check_blacklist} && $param) {
# is the parameter value blacklisted?

... in your validation class:

    package MyApp::Person;
    use Validation::Class;
    field ip_address => {
        required        => 1,
        check_blacklist => 1
    };
    1;

... in your application:

    package main;
    use MyApp::Person;
    my $person = MyApp::Person->new(ip_address => '0.0.0.0');
    unless ($person->validates('ip_address')) {
        # handle validation error
    }

DESCRIPTION

You can extend Validation::Class by creating your own validation rules (directives). Validation::Class::Directive provides a base-class for you to use when creating new directive classes. Please see Validation::Class::Directives for a complete list of core directives.
