13 This class represents type constraints for a role.
14
16 "Moose::Meta::TypeConstraint::Role" is a subclass of
17 Moose::Meta::TypeConstraint.
18
20 Moose::Meta::TypeConstraint::Role->new(%options)
21 This creates a new role type constraint based on the given %options.
22
23 It takes the same options as its parent, with two exceptions. First, it
24 requires an additional option, "role", which is name of the
25 constraint's role. Second, it automatically sets the parent to the
26 "Object" type.
27
28 The constructor also overrides the hand optimized type constraint with
29 one it creates internally.
30
31 $constraint->role
32 Returns the role name associated with the constraint.
33
34 $constraint->parents
35 Returns all the type's parent types, corresponding to the roles that
36 its role does.
37
38 $constraint->is_subtype_of($type_name_or_object)
39 If the given type is also a role type, then this checks that the type's
40 role does the other type's role.
41
42 Otherwise it falls back to the implementation in
43 Moose::Meta::TypeConstraint.
44
45 $constraint->create_child_type(%options)
46 This returns a new Moose::Meta::TypeConstraint object with the type as
47 its parent.
48
49 Note that it does not return a "Moose::Meta::TypeConstraint::Role"
50 object!
