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! | ||||
