interface RevisionableInterface in Drupal 10

Provides methods for an entity to support revisions.

Classes implementing this interface do not necessarily support revisions.

To detect whether an entity type supports revisions, call EntityTypeInterface::isRevisionable().

Many entity interfaces are composed of numerous other interfaces such as this one, which allow implementations to pick and choose which features to. support through stub implementations of various interface methods. This means that even if an entity class implements RevisionableInterface, it might only have a stub implementation and not a functional one.
