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! | ||||
