81 | =head1 NAME | ||||
82 | |||||
83 | Moose::Meta::TypeConstraint::Enum - Type constraint for enumerated values. | ||||
84 | |||||
85 | =head1 DESCRIPTION | ||||
86 | |||||
87 | This class represents type constraints based on an enumerated list of | ||||
88 | acceptable values. | ||||
89 | |||||
90 | =head1 INHERITANCE | ||||
91 | |||||
92 | C<Moose::Meta::TypeConstraint::Enum> is a subclass of | ||||
93 | L<Moose::Meta::TypeConstraint>. | ||||
94 | |||||
95 | =head1 METHODS | ||||
96 | |||||
97 | =over 4 | ||||
98 | |||||
99 | =item B<< Moose::Meta::TypeConstraint::Enum->new(%options) >> | ||||
100 | |||||
101 | This creates a new enum type constraint based on the given | ||||
102 | C<%options>. | ||||
103 | |||||
104 | It takes the same options as its parent, with several | ||||
105 | exceptions. First, it requires an additional option, C<values>. This | ||||
106 | should be an array reference containing a list of valid string | ||||
107 | values. Second, it automatically sets the parent to the C<Str> type. | ||||
108 | |||||
109 | Finally, it ignores any provided C<constraint> option. The constraint | ||||
110 | is generated automatically based on the provided C<values>. | ||||
111 | |||||
112 | =item B<< $constraint->values >> | ||||
113 | |||||
114 | Returns the array reference of acceptable values provided to the | ||||
115 | constructor. | ||||
116 | |||||
117 | =item B<< $constraint->create_child_type >> | ||||
118 | |||||
119 | This returns a new L<Moose::Meta::TypeConstraint> object with the type | ||||
120 | as its parent. | ||||
121 | |||||
122 | Note that it does I<not> return a C<Moose::Meta::TypeConstraint::Enum> | ||||
123 | object! | ||||
