MooseX::Meta::TypeConstraint::ForceCoercion - Force coercion when
validating type constraints
VERSION
version 0.01
SYNOPSIS
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
$coercing_tc->check('Affe');
DESCRIPTION
This class allows to wrap any "Moose::Meta::TypeConstraint" in a way
that will force coercion of the value when checking or validating a
value against it.
ATTRIBUTES
type_constraint
The type constraint to wrap. All methods except for "validate" and
"check" are delegated to the value of this attribute.
METHODS
check ($value)
Same as "Moose::Meta::TypeConstraint::check", except it will always try
to coerce $value before checking it against the actual type constraint.
If coercing fails the check will fail, too.
validate ($value, $coerced_ref?)
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.
If coercion was successful and a $coerced_ref references was passed,
the coerced value will be stored in that.
