.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Validation::Class::Simple is a simple validation module built around the
powerful Validation::Class data validation framework.
.PP
This module is merely a blank canvas, a clean validation class derived from
Validation::Class which has not been pre-configured (e.g. configured via
keywords, etc).
.PP
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.
.SH "QUICKSTART"
.IX Header "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
Validation::Class::Simple::Streamer. Please review the
\&\*(L"GUIDED-TOUR\*(R" in Validation::Class::Cookbook for a detailed step-by-step look
into how Validation::Class works.
.SH "RATIONALE"
.IX Header "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 Validation::Class::Whitepaper.
.SH "PROXY METHODS"
.IX Header "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 Validation::Class::Prototype for
more information on specific methods and attributes.
.PP
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.
