This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
public interface AttributeView
An object that provides a read-only or updatable view of non-opaque
values associated with an object in a filesystem. This interface is extended
or implemented by specific attribute views that define the attributes
supported by the view. A specific attribute view will typically define
type-safe methods to read or update the attributes that it supports.
