Moose::Meta::TypeConstraint::Class(3pm)

NAME

Moose::Meta::TypeConstraint::Class - Class/TypeConstraint parallel
hierarchy

This class represents type constraints for a class.

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

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.

See "BUGS" in Moose for details on reporting bugs.
