Class BufferedJournalRecoveryLog

java.lang.Object
  org.fcrepo.server.journal.recoverylog.JournalRecoveryLog
      org.fcrepo.server.journal.recoverylog.BufferedJournalRecoveryLog

All Implemented Interfaces:

JournalConstants

public class BufferedJournalRecoveryLog
extends JournalRecoveryLog

A simple implementation of JournalRecoveryLog that keeps the entire log in a StringBuffer, and writes it to a file on shutdown().

This is memory-intensive, so it should only be used for System Tests, where the presence of the log file can be treated as a signal that the recovery is complete.
