=head1 NAME

Validation::Class::Simple - Simple Ad-Hoc Data Validation

=head1 VERSION

version 7.900054

=head1 SYNOPSIS

    use Validation::Class::Simple;

    my $params = {
        name  => 'Root',
        email => 'root@localhost',
        pass  => 's3cret',
        pass2 => 's2cret'
    };

    # define object specific rules
    my $rules = Validation::Class::Simple->new(
        # define fields on-the-fly
        fields => {
            name  => { required => 1 },
            email => { required => 1 },
            pass  => { required => 1 },
            pass2 => { required => 1, matches => 'pass' },
        }
    );

    # set parameters to be validated
    $rules->params->add($params);

    # validate
    unless ($rules->validate) {
        # handle the failures
        warn $rules->errors_to_string;
    }

=head1 DESCRIPTION

Validation::Class::Simple is a simple validation module built around the
powerful L<Validation::Class> data validation framework.

This module is merely a blank canvas, a clean validation class derived from
L<Validation::Class> which has not been pre-configured (e.g. configured via
keywords, etc).

It can be useful in an environment where you wouldn't care to create a
validation class and instead would simply like to pass rules to a validation
engine in an ad-hoc fashion.

=head1 QUICKSTART

If you are looking for a data validation module with an even lower learning
curve built using the same tenets and principles as Validation::Class which is
as simple and even lazier than this module, please review the documentation for
L<Validation::Class::Simple::Streamer>. Please review the
L<Validation::Class::Cookbook/GUIDED-TOUR> for a detailed step-by-step look
into how Validation::Class works.

=head1 RATIONALE

If you are new to Validation::Class, or would like more information on the
underpinnings of this library and how it views and approaches data validation,
please review L<Validation::Class::Whitepaper>.

=head1 PROXY METHODS

Each instance of Validation::Class::Simple is associated with a prototype class
which provides the data validation engine and keeps the class namespace free
from pollution and collisions, please see L<Validation::Class::Prototype> for
more information on specific methods and attributes.

Validation::Class::Simple is injected with a few proxy methods which are
basically aliases to the corresponding prototype (engine) class methods,
however it is possible to access the prototype directly using the
proto/prototype methods.
