NAME ^

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

VERSION ^

version 2.0604

DESCRIPTION ^

This class represents type constraints for a role.

INHERITANCE ^

Moose::Meta::TypeConstraint::Role is a subclass of Moose::Meta::TypeConstraint.

METHODS ^

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

This creates a new role type constraint based on the given %options.

It takes the same options as its parent, with two exceptions. First, it requires an additional option, role, which is name of the constraint's role. 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->role

Returns the role name associated with the constraint.

$constraint->parents

Returns all the type's parent types, corresponding to the roles that its role does.

$constraint->is_subtype_of($type_name_or_object)

If the given type is also a role type, then this checks that the type's role does the other type's role.

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::Role object!
