Class JournalCreator

java.lang.Object
  org.fcrepo.server.journal.JournalCreator

All Implemented Interfaces:

JournalConstants, JournalWorker, Management

public class JournalCreator
extends Object
implements JournalWorker, JournalConstants

This is the worker class to use in Journaling mode (normal mode).

Each time a "writing" Management method is called, create a CreatorJournalEntry and ask it to invoke the method on the ManagementDelegate. If a "read-only" Management method is called, just pass it along to the ManagementDelegate.
