| 109 | =head1 NAME | |||
| 110 | ||||
| 111 | Moose::Meta::TypeConstraint::Role - Role/TypeConstraint parallel hierarchy | |||
| 112 | ||||
| 113 | =head1 DESCRIPTION | |||
| 114 | ||||
| 115 | This class represents type constraints for a role. | |||
| 116 | ||||
| 117 | =head1 INHERITANCE | |||
| 118 | ||||
| 119 | C<Moose::Meta::TypeConstraint::Role> is a subclass of | |||
| 120 | L<Moose::Meta::TypeConstraint>. | |||
| 121 | ||||
| 122 | =head1 METHODS | |||
| 123 | ||||
| 124 | =over 4 | |||
| 125 | ||||
| 126 | =item B<< Moose::Meta::TypeConstraint::Role->new(%options) >> | |||
| 127 | ||||
| 128 | This creates a new role type constraint based on the given | |||
| 129 | C<%options>. | |||
| 130 | ||||
| 131 | It takes the same options as its parent, with two exceptions. First, | |||
| 132 | it requires an additional option, C<role>, which is name of the | |||
| 133 | constraint's role. Second, it automatically sets the parent to the | |||
| 134 | C<Object> type. | |||
| 135 | ||||
| 136 | The constructor also overrides the hand optimized type constraint with | |||
| 137 | one it creates internally. | |||
| 138 | ||||
| 139 | =item B<< $constraint->role >> | |||
| 140 | ||||
| 141 | Returns the role name associated with the constraint. | |||
| 142 | ||||
| 143 | =item B<< $constraint->parents >> | |||
| 144 | ||||
| 145 | Returns all the type's parent types, corresponding to the roles that | |||
| 146 | its role does. | |||
| 147 | ||||
| 148 | =item B<< $constraint->is_subtype_of($type_name_or_object) >> | |||
| 149 | ||||
| 150 | If the given type is also a role type, then this checks that the | |||
| 151 | type's role does the other type's role. | |||
| 152 | ||||
| 153 | Otherwise it falls back to the implementation in | |||
| 154 | L<Moose::Meta::TypeConstraint>. | |||
| 155 | ||||
| 156 | =item B<< $constraint->create_child_type(%options) >> | |||
| 157 | ||||
| 158 | This returns a new L<Moose::Meta::TypeConstraint> object with the type | |||
| 159 | as its parent. | |||
| 160 | ||||
| 161 | Note that it does I<not> return a C<Moose::Meta::TypeConstraint::Role> | |||
| 162 | object! | |||
