| FileProcessor | | class FileProcessor extends DaemonThread (Code) | | Reads all entries in a log file and either determines them to be obsolete or
marks them for migration. LNs are marked for migration by setting the BIN

May be invoked explicitly by calling doClean, or woken up if used as a
daemon thread.

| void | addSentinalWorkObject()
Adds a sentinal object to the work queue to force onWakeup to be
called immediately after setting je.env.runCleaner=true. | | public void | addToQueue(Object o)
Cleaner doesn't have a work queue so just throw an exception if it's
ever called. | | public void | clearEnv()
| | public synchronized int | doClean(boolean invokedFromDaemon, boolean cleanMultipleFiles, boolean forceCleaning)
Cleans selected files and returns the number of files cleaned. | | protected int | nDeadlockRetries()
Return the number of retries when a deadlock exception occurs. | | public void | onWakeup()
Activates the cleaner. |
| addSentinalWorkObject | | void addSentinalWorkObject()(Code) | | Adds a sentinal object to the work queue to force onWakeup to be
