| 97 | =head1 NAME | |||
| 98 | ||||
| 99 | Moose::Meta::TypeConstraint::Enum - Type constraint for enumerated values. | |||
| 100 | ||||
| 101 | =head1 DESCRIPTION | |||
| 102 | ||||
| 103 | This class represents type constraints based on an enumerated list of | |||
| 104 | acceptable values. | |||
| 105 | ||||
| 106 | =head1 INHERITANCE | |||
| 107 | ||||
| 108 | C<Moose::Meta::TypeConstraint::Enum> is a subclass of | |||
| 109 | L<Moose::Meta::TypeConstraint>. | |||
| 110 | ||||
| 111 | =head1 METHODS | |||
| 112 | ||||
| 113 | =over 4 | |||
| 114 | ||||
| 115 | =item B<< Moose::Meta::TypeConstraint::Enum->new(%options) >> | |||
| 116 | ||||
| 117 | This creates a new enum type constraint based on the given | |||
| 118 | C<%options>. | |||
| 119 | ||||
| 120 | It takes the same options as its parent, with several | |||
| 121 | exceptions. First, it requires an additional option, C<values>. This | |||
| 122 | should be an array reference containing a list of valid string | |||
| 123 | values. Second, it automatically sets the parent to the C<Str> type. | |||
| 124 | ||||
| 125 | Finally, it ignores any provided C<constraint> option. The constraint | |||
| 126 | is generated automatically based on the provided C<values>. | |||
| 127 | ||||
| 128 | =item B<< $constraint->values >> | |||
| 129 | ||||
| 130 | Returns the array reference of acceptable values provided to the | |||
| 131 | constructor. | |||
| 132 | ||||
| 133 | =item B<< $constraint->create_child_type >> | |||
| 134 | ||||
| 135 | This returns a new L<Moose::Meta::TypeConstraint> object with the type | |||
| 136 | as its parent. | |||
| 137 | ||||
| 138 | Note that it does I<not> return a C<Moose::Meta::TypeConstraint::Enum> | |||
| 139 | object! | |||
