Moose::Meta::TypeConstraint::Registry - registry for type constraints

version 2.0010

This class is a registry that maps type constraint names to Moose::Meta::TypeConstraint objects.

Currently, it is only used internally by Moose::Util::TypeConstraints, which creates a single global registry.

Moose::Meta::TypeConstraint::Registry is a subclass of Class::MOP::Object.

Moose::Meta::TypeConstraint::Registry->new(%options)

This creates a new registry object based on the provided %options:

* parent_registry

This is an optional Moose::Meta::TypeConstraint::Registry object.

* type_constraints

This is hash reference of type names to type objects. This is optional. Constraints can be added to the registry after it is created.

$registry->get_parent_registry

Returns the registry's parent registry, if it has one.

$registry->has_parent_registry

Returns true if the registry has a parent.

$registry->set_parent_registry($registry)

Sets the parent registry.

$registry->get_type_constraint($type_name)

This returns the Moose::Meta::TypeConstraint object from the registry for the given name, if one exists.

$registry->has_type_constraint($type_name)

Returns true if the registry has a type of the given name.

$registry->add_type_constraint($type)

Adds a new Moose::Meta::TypeConstraint object to the registry.

$registry->find_type_constraint($type_name)

This method looks in the current registry for the named type. If the type is not found, then this method will look in the registry's parent, if it has one.
