Description

       This class represents type constraints for a class.

Inheritance

       "Moose::Meta::TypeConstraint::Class" is a subclass of Moose::Meta::TypeConstraint.

Methods

Moose::Meta::TypeConstraint::Class->new(%options)
       This creates a new class type constraint based on the given %options.

       It takes the same options as its parent, with two exceptions. First, it requires an additional option,
       "class", which is name of the constraint's class.  Second, it automatically sets the parent to the
       "Object" type.

       The constructor also overrides the hand optimized type constraint with one it creates internally.

   $constraint->class
       Returns the class name associated with the constraint.

   $constraint->parents
       Returns all the type's parent types, corresponding to its parent classes.

   $constraint->is_subtype_of($type_name_or_object)
       If the given type is also a class type, then this checks that the type's class is a subclass of the other
       type's class.

       Otherwise it falls back to the implementation in Moose::Meta::TypeConstraint.

   $constraint->create_child_type(%options)
       This returns a new Moose::Meta::TypeConstraint object with the type as its parent.

       Note that it does not return a "Moose::Meta::TypeConstraint::Class" object!

   $constraint->get_message($value)
       This is the same as "get_message" in Moose::Meta::TypeConstraint except that it explicitly says "isa" was
       checked. This is to help users deal with accidentally autovivified type constraints.
