13 Validation::Class::Directives provides a collection of installed
14 Validation::Class directives. This class inherits from
15 Validation::Class::Mapping. Please look at Validation::Class::Directive
16 for information of developing your own directives.
17
19 The following is a list of core directives that get installed
20 automatically with Validation::Class and can be used to jump-start your
21 data validation initiative. Please Note! The purpose of the core
22 directives is merely to provide a reasonable layer of protection
23 against bad/malformed data, the validators are not very sophisticated
24 and were created using a minimal level of strictness (e.g. the email
25 and hostname directives do not perform a hostname lookup nor does the
26 email directive conform to the RFC specification).
27 Various applications have varied levels of strictness regarding various
29 types of input (e.g. a hospital API may require a more sophisticated
30 SSN validation than that of a department of education API; likewise; an
31 email service API may require a more sophisticated email validation
32 than that of a file sharing API). Validation::Class does not attempt
33 to provide validators for all levels of strictness and the core
34 directives exist to support typical use-cases with a minimal level of
35 strictness.
