NAME
Moose::Meta::TypeConstraint::Role - Role/TypeConstraint parallel
hierarchy
VERSION
version 2.2200
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!
