NAME

MooseX::Meta::TypeConstraint::ForceCoercion - Force coercion when validating type constraints

CONTENTS

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 couldnt 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 ($value, CW$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.
