NAME

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

CONTENTS

VERSION

version 2.1605

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.

CW$constraint->class

Returns the class name associated with the constraint.

CW$constraint->parents

Returns all the type’s parent types, corresponding to its parent classes.

CW$constraint->is_subtype_of($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.

CW$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!

CW$constraint->get_message($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.

BUGS

See BUGS in Moose for details on reporting bugs.
