@InterfaceAudience.Public
@InterfaceStability.Evolving
public class InterfaceStability
extends Object

Annotation to inform users of how much to rely on a particular package, class or method not changing over time. Currently the stability can be InterfaceStability.Stable, InterfaceStability.Evolving or InterfaceStability.Unstable.

• All classes that are annotated with InterfaceAudience.Public or InterfaceAudience.LimitedPrivate must have InterfaceStability annotation.
• Classes that are InterfaceAudience.LimitedPrivate are to be considered unstable unless a different InterfaceStability annotation states otherwise.
• Incompatible changes must not be made to classes marked as stable.
