NAME

       Params::Validate::Dummy - Stub for Params::Validate

SYNOPSIS

	 use Params::Validate::Dummy qw();
	 use Module::Optional qw(Params::Validate);

DESCRIPTION

       This module provides stub routines for those who don't have Params::Validate installed.

       For more details, please refer to the documentation for Params::Validate.

       The code here is just stub routines which do NOTHING at all, passing through any arguments in the API and prototypes of Params::Validate.
       In particular, the dummy stubs do not do defaulting, validation, untainting or anything else that Params::Validate does. If you need this
       functionality, either provide it yourself in the surrounding code, or don't use this module and insist that the real Params::Validate is
       installed.

   "validate", "validate_pos"
       The parameter list is passed through as a return value.

   "validate_with"
       Returns the value of the params option.

   "set_options", "validation_options"
       These do nothing at all.

   Data types: "SCALAR", "SCALARREF", "ARRAYREF", "HASHREF", "GLOB", "GLOBREF", "BOOLEAN", "CODEREF", "HANDLE", "OBJECT", "UNDEF", "UNKNOWN"
       In the Params::Validate module, these are constants implemented by subs that return numbers. This module implements the same functions.

NAME

       Attribute::Params::Validate - Define validation through subroutine attributes

VERSION

       version 1.08

SYNOPSIS

	 use Attribute::Params::Validate qw(:all);

	 # takes named params (hash or hashref)
	 # foo is mandatory, bar is optional
	 sub foo : Validate( foo => 1, bar => 0 )
	 {
	     ...
	 }

	 # takes positional params
	 # first two are mandatory, third is optional
	 sub bar : ValidatePos( 1, 1, 0 )
	 {
	     ...
	 }

	 # for some reason Perl insists that the entire attribute be on one line
	 sub foo2 : Validate( foo => { type => ARRAYREF }, bar => { can => [ 'print', 'flush', 'frobnicate' ] }, baz => { type => SCALAR, callbacks => { 'numbers only' => sub { shift() =~ /^d+$/ }, 'less than 90' => sub { shift() < 90 } } } )
	 {
	     ...
	 }

	 # note that this is marked as a method.  This is very important!
	 sub baz : Validate( foo => { type => ARRAYREF }, bar => { isa => 'Frobnicator' } ) method
	 {
	     ...
	 }

DESCRIPTION

       The Attribute::Params::Validate module allows you to validate method or function call parameters just like Params::Validate does.  However,
       this module allows you to specify your validation spec as an attribute, rather than by calling the "validate" routine.

       Please see Params::Validate for more information on how you can specify what validation is performed.

   EXPORT
       This module exports everything that Params::Validate does except for the "validate" and "validate_pos" subroutines.

   ATTRIBUTES
       o   Validate

	   This attribute corresponds to the "validate" subroutine in Params::Validate.

       o   ValidatePos

	   This attribute corresponds to the "validate_pos" subroutine in Params::Validate.

   OO
       If you are using this module to mark methods for validation, as opposed to subroutines, it is crucial that you mark these methods with the
       ":method" attribute, as well as the "Validate" or "ValidatePos" attribute.

       If you do not do this, then the object or class used in the method call will be passed to the validation routines, which is probably not
       what you want.

   CAVEATS
       You must put all the arguments to the "Validate" or "ValidatePos" attribute on a single line, or Perl will complain.
