MooseX::Meta::TypeConstraint::ForceCoercion - Force coercion when validating type constraints
version 0.01
use MooseX::Types:::Moose qw/Str Any/; use Moose::Util::TypeConstraints; use MooseX::Meta::TypeConstraint::ForceCoercion; # get any type constraint my $tc = Str; # declare one or more coercions for it coerce $tc, from Any, via { ... }; # wrap the $tc to force coercion my $coercing_tc = MooseX::Meta::TypeConstraint::ForceCoercion->new( type_constraint => $tc, ); # check a value against new type constraint. this will run the type # coercions for the wrapped type, even if the value already passes # validation before coercion. it will fail if the value couldn't be # coerced $coercing_tc->check('Affe');
This class allows to wrap any Moose::Meta::TypeConstraint in a way that will force coercion of the value when checking or validating a value against it.
Moose::Meta::TypeConstraint
The type constraint to wrap. All methods except for validate and check are delegated to the value of this attribute.
validate
check
Same as Moose::Meta::TypeConstraint::check, except it will always try to coerce $value before checking it against the actual type constraint. If coercing fails the check will fail, too.
Moose::Meta::TypeConstraint::check
$value
Same as Moose::Meta::TypeConstraint::validate, except it will always try to coerce $value before validating it against the actual type constraint. If coercing fails the validation will fail, too.
Moose::Meta::TypeConstraint::validate
If coercion was successful and a $coerced_ref references was passed, the coerced value will be stored in that.
$coerced_ref
