Examples of org.hornetq.core.journal.Journal

org.hornetq.core.journal.Journal
Most methods on the journal provide a blocking version where you select the sync mode and a non blocking mode where you pass a completion callback as a parameter. Notice also that even on the callback methods it's possible to pass the sync mode. That will only make sense on the NIO operations. @author Tim Fox @author Clebert Suconic
