| 109 | =head1 NAME | ||||
| 110 | |||||
| 111 | Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing | ||||
| 112 | |||||
| 113 | =head1 DESCRIPTION | ||||
| 114 | |||||
| 115 | This class represents type constraints based on an enumerated list of | ||||
| 116 | required methods. | ||||
| 117 | |||||
| 118 | =head1 INHERITANCE | ||||
| 119 | |||||
| 120 | C<Moose::Meta::TypeConstraint::DuckType> is a subclass of | ||||
| 121 | L<Moose::Meta::TypeConstraint>. | ||||
| 122 | |||||
| 123 | =head1 METHODS | ||||
| 124 | |||||
| 125 | =over 4 | ||||
| 126 | |||||
| 127 | =item B<< Moose::Meta::TypeConstraint::DuckType->new(%options) >> | ||||
| 128 | |||||
| 129 | This creates a new duck type constraint based on the given | ||||
| 130 | C<%options>. | ||||
| 131 | |||||
| 132 | It takes the same options as its parent, with several | ||||
| 133 | exceptions. First, it requires an additional option, C<methods>. This | ||||
| 134 | should be an array reference containing a list of required method | ||||
| 135 | names. Second, it automatically sets the parent to the C<Object> type. | ||||
| 136 | |||||
| 137 | Finally, it ignores any provided C<constraint> option. The constraint | ||||
| 138 | is generated automatically based on the provided C<methods>. | ||||
| 139 | |||||
| 140 | =item B<< $constraint->methods >> | ||||
| 141 | |||||
| 142 | Returns the array reference of required methods provided to the | ||||
| 143 | constructor. | ||||
| 144 | |||||
| 145 | =item B<< $constraint->create_child_type >> | ||||
| 146 | |||||
| 147 | This returns a new L<Moose::Meta::TypeConstraint> object with the type | ||||
| 148 | as its parent. | ||||
| 149 | |||||
| 150 | Note that it does I<not> return a C<Moose::Meta::TypeConstraint::DuckType> | ||||
| 151 | object! | ||||
| 152 | |||||
