.SH "NAME"
Moose::Meta::TypeConstraint::Registry \- registry for type constraints
.SH "VERSION"
.IX Header "VERSION"
version 2.2201
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class is a registry that maps type constraint names to
Moose::Meta::TypeConstraint objects.
.PP
Currently, it is only used internally by
Moose::Util::TypeConstraints, which creates a single global
registry.
.SH "INHERITANCE"
.IX Header "INHERITANCE"
\&\f(CW\*(C`Moose::Meta::TypeConstraint::Registry\*(C'\fR is a subclass of
Class::MOP::Object.
.SH "METHODS"
.IX Header "METHODS"
.SS "Moose::Meta::TypeConstraint::Registry\->new(%options)"
.IX Subsection "Moose::Meta::TypeConstraint::Registry->new(%options)"
This creates a new registry object based on the provided \f(CW%options\fR:
.IP "\(bu" 4
parent_registry
.Sp
This is an optional Moose::Meta::TypeConstraint::Registry
object.
.IP "\(bu" 4
type_constraints
.Sp
This is hash reference of type names to type objects. This is
optional. Constraints can be added to the registry after it is
created.
.ie n .SS "$registry\->get_parent_registry"
.el .SS "\f(CW$registry\fP\->get_parent_registry"
.IX Subsection "$registry->get_parent_registry"
Returns the registry's parent registry, if it has one.
.ie n .SS "$registry\->has_parent_registry"
.el .SS "\f(CW$registry\fP\->has_parent_registry"
.IX Subsection "$registry->has_parent_registry"
Returns true if the registry has a parent.
.ie n .SS "$registry\->set_parent_registry($registry)"
.el .SS "\f(CW$registry\fP\->set_parent_registry($registry)"
.IX Subsection "$registry->set_parent_registry($registry)"
Sets the parent registry.
.ie n .SS "$registry\->get_type_constraint($type_name)"
.el .SS "\f(CW$registry\fP\->get_type_constraint($type_name)"
.IX Subsection "$registry->get_type_constraint($type_name)"
This returns the Moose::Meta::TypeConstraint object from the
registry for the given name, if one exists.
.ie n .SS "$registry\->has_type_constraint($type_name)"
.el .SS "\f(CW$registry\fP\->has_type_constraint($type_name)"
.IX Subsection "$registry->has_type_constraint($type_name)"
Returns true if the registry has a type of the given name.
.ie n .SS "$registry\->add_type_constraint($type)"
.el .SS "\f(CW$registry\fP\->add_type_constraint($type)"
.IX Subsection "$registry->add_type_constraint($type)"
Adds a new Moose::Meta::TypeConstraint object to the registry.
.ie n .SS "$registry\->find_type_constraint($type_name)"
.el .SS "\f(CW$registry\fP\->find_type_constraint($type_name)"
.IX Subsection "$registry->find_type_constraint($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.
