10 This class represents type constraints for a role.
11
13 "Moose::Meta::TypeConstraint::Role" is a subclass of
14 Moose::Meta::TypeConstraint.
15
17 Moose::Meta::TypeConstraint::Role->new(%options)
18 This creates a new role type constraint based on the given
19 %options.
20
21 It takes the same options as its parent, with two exceptions.
22 First, it requires an additional option, "role", which is name of
23 the constraint's role. Second, it automatically sets the parent to
24 the "Object" type.
25
26 The constructor also overrides the hand optimized type constraint
27 with one it creates internally.
28
29 $constraint->role
30 Returns the role name associated with the constraint.
31
32 $constraint->parents
33 Returns all the type's parent types, corresponding to the roles
34 that its role does.
35
36 $constraint->is_subtype_of($type_name_or_object)
37 If the given type is also a role type, then this checks that the
38 type's role does the other type's role.
39
40 Otherwise it falls back to the implementation in
41 Moose::Meta::TypeConstraint.
42
43 $constraint->create_child_type(%options)
44 This returns a new Moose::Meta::TypeConstraint object with the type
45 as its parent.
46
47 Note that it does not return a "Moose::Meta::TypeConstraint::Role"
48 object!
