NAME

Data::TreeValidator::Constraints - A collection of constraints for validating data

SYNOPSIS

    use Data::TreeValidator::Constraints qw( required );

DESCRIPTION

Constraints currently take a single form, a subroutine reference. If the data does not validate, an exception will be raised (which is caught by process methods). If an exception is not raised, the data will be assumed to be valid.

All methods below are available for importing into using modules

FUNCTIONS

required

Checks that $input is defined, and stringifies to a true value (not the empty string)

length min => $min, max => $max

Checks that a given input is between $min and $max. You do not have to specify both parameters, either or is also fine.

options @options

Checks that a given input is in the set defined by @options.

type $type_constraint

Checks that a given input satisfies a given Moose::Meta::TypeConstraint. E.g.

use MooseX::Types::Moose qw/Num/; type(Num);
