public abstract class AbstractPersister extends Object implements Persister
This abstract class provides two services to concrete subclasses: First, it stores the configuration and actorId of the Actor instance for which it applies. Second, it provides a consistent file naming service in the case of a persister that uses disk file(s). A Subclass is not required to use the naming service(s).
