111 | # ABSTRACT: Type constraint for duck typing | ||||
112 | |||||
- - | |||||
115 | =pod | ||||
116 | |||||
117 | =head1 NAME | ||||
118 | |||||
119 | Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing | ||||
120 | |||||
121 | =head1 VERSION | ||||
122 | |||||
123 | version 2.0602 | ||||
124 | |||||
125 | =head1 DESCRIPTION | ||||
126 | |||||
127 | This class represents type constraints based on an enumerated list of | ||||
128 | required methods. | ||||
129 | |||||
130 | =head1 INHERITANCE | ||||
131 | |||||
132 | C<Moose::Meta::TypeConstraint::DuckType> is a subclass of | ||||
133 | L<Moose::Meta::TypeConstraint>. | ||||
134 | |||||
135 | =head1 METHODS | ||||
136 | |||||
137 | =over 4 | ||||
138 | |||||
139 | =item B<< Moose::Meta::TypeConstraint::DuckType->new(%options) >> | ||||
140 | |||||
141 | This creates a new duck type constraint based on the given | ||||
142 | C<%options>. | ||||
143 | |||||
144 | It takes the same options as its parent, with several | ||||
145 | exceptions. First, it requires an additional option, C<methods>. This | ||||
146 | should be an array reference containing a list of required method | ||||
147 | names. Second, it automatically sets the parent to the C<Object> type. | ||||
148 | |||||
149 | Finally, it ignores any provided C<constraint> option. The constraint | ||||
150 | is generated automatically based on the provided C<methods>. | ||||
151 | |||||
152 | =item B<< $constraint->methods >> | ||||
153 | |||||
154 | Returns the array reference of required methods provided to the | ||||
155 | constructor. | ||||
156 | |||||
157 | =item B<< $constraint->create_child_type >> | ||||
158 | |||||
159 | This returns a new L<Moose::Meta::TypeConstraint> object with the type | ||||
160 | as its parent. | ||||
161 | |||||
162 | Note that it does I<not> return a C<Moose::Meta::TypeConstraint::DuckType> | ||||
163 | object! | ||||
