52 | =head1 NAME | |||
53 | ||||
54 | Moose::Meta::TypeCoercion::Union - The Moose Type Coercion metaclass for Unions | |||
55 | ||||
56 | =head1 DESCRIPTION | |||
57 | ||||
58 | This is a subclass of L<Moose::Meta::TypeCoercion> that is used for | |||
59 | L<Moose::Meta::TypeConstraint::Union> objects. | |||
60 | =head1 METHODS | |||
61 | ||||
62 | =over 4 | |||
63 | ||||
64 | =item B<< $coercion->has_coercion_for_type >> | |||
65 | ||||
66 | This method always returns false. | |||
67 | ||||
68 | =item B<< $coercion->add_type_coercions >> | |||
69 | ||||
70 | This method always throws an error. You cannot add coercions to a | |||
71 | union type coercion. | |||
72 | ||||
73 | =item B<< $coercion->coerce($value) >> | |||
74 | ||||
75 | This method will coerce by trying the coercions for each type in the | |||
76 | union. | |||
