127 | =head1 NAME | ||||
128 | |||||
129 | Moose::Meta::TypeConstraint::Class - Class/TypeConstraint parallel hierarchy | ||||
130 | |||||
131 | =head1 DESCRIPTION | ||||
132 | |||||
133 | This class represents type constraints for a class. | ||||
134 | |||||
135 | =head1 INHERITANCE | ||||
136 | |||||
137 | C<Moose::Meta::TypeConstraint::Class> is a subclass of | ||||
138 | L<Moose::Meta::TypeConstraint>. | ||||
139 | |||||
140 | =head1 METHODS | ||||
141 | |||||
142 | =over 4 | ||||
143 | |||||
144 | =item B<< Moose::Meta::TypeConstraint::Class->new(%options) >> | ||||
145 | |||||
146 | This creates a new class type constraint based on the given | ||||
147 | C<%options>. | ||||
148 | |||||
149 | It takes the same options as its parent, with two exceptions. First, | ||||
150 | it requires an additional option, C<class>, which is name of the | ||||
151 | constraint's class. Second, it automatically sets the parent to the | ||||
152 | C<Object> type. | ||||
153 | |||||
154 | The constructor also overrides the hand optimized type constraint with | ||||
155 | one it creates internally. | ||||
156 | |||||
157 | =item B<< $constraint->class >> | ||||
158 | |||||
159 | Returns the class name associated with the constraint. | ||||
160 | |||||
161 | =item B<< $constraint->parents >> | ||||
162 | |||||
163 | Returns all the type's parent types, corresponding to its parent | ||||
164 | classes. | ||||
165 | |||||
166 | =item B<< $constraint->is_subtype_of($type_name_or_object) >> | ||||
167 | |||||
168 | If the given type is also a class type, then this checks that the | ||||
169 | type's class is a subclass of the other type's class. | ||||
170 | |||||
171 | Otherwise it falls back to the implementation in | ||||
172 | L<Moose::Meta::TypeConstraint>. | ||||
173 | |||||
174 | =item B<< $constraint->create_child_type(%options) >> | ||||
175 | |||||
176 | This returns a new L<Moose::Meta::TypeConstraint> object with the type | ||||
177 | as its parent. | ||||
178 | |||||
179 | Note that it does I<not> return a | ||||
180 | C<Moose::Meta::TypeConstraint::Class> object! | ||||
181 | |||||
182 | =item B<< $constraint->get_message($value) >> | ||||
183 | |||||
184 | This is the same as L<Moose::Meta::TypeConstraint/get_message> except | ||||
185 | that it explicitly says C<isa> was checked. This is to help users deal | ||||
186 | with accidentally autovivified type constraints. | ||||
187 | |||||
