Class InterfaceAudience

java.lang.Object

org.apache.hadoop.classification.InterfaceAudience

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

Annotation to inform users of a package, class or method's intended audience. Currently the audience can be InterfaceAudience.Public, InterfaceAudience.LimitedPrivate or InterfaceAudience.Private.
All public classes must have InterfaceAudience annotation.

• Public classes that are not marked with this annotation must be considered by default as InterfaceAudience.Private.
• External applications must only use classes that are marked InterfaceAudience.Public. Avoid using non public classes as these classes could be removed or change in incompatible ways.
• Hadoop projects must only use classes that are marked InterfaceAudience.LimitedPrivate or InterfaceAudience.Public
• Methods may have a different annotation that it is more restrictive compared to the audience classification of the class. Example: A class might be InterfaceAudience.Public, but a method may be InterfaceAudience.LimitedPrivate
