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