8
10 This class represents type constraints for a class.
11
13 "Moose::Meta::TypeConstraint::Class" is a subclass of
14 Moose::Meta::TypeConstraint.
15
17 Moose::Meta::TypeConstraint::Class->new(%options)
18 This creates a new class 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, "class", which is name of
23 the constraint's class. Second, it automatically sets the parent
24 to the "Object" type.
25
26 The constructor also overrides the hand optimized type constraint
27 with one it creates internally.
28
29 $constraint->class
30 Returns the class name associated with the constraint.
31
32 $constraint->parents
33 Returns all the type's parent types, corresponding to its parent
34 classes.
35
36 $constraint->is_subtype_of($type_name_or_object)
37 If the given type is also a class type, then this checks that the
38 type's class is a subclass of the other type's class.
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::Class"
48 object!
49
50 $constraint->get_message($value)
51 This is the same as "get_message" in Moose::Meta::TypeConstraint
52 except that it explicitly says "isa" was checked. This is to help
53 users deal with accidentally autovivified type constraints.
54
56 See "BUGS" in Moose for details on reporting bugs.
