Examples of com.sleepycat.je.txn.Txn$DatabaseCleanupInfo

com.sleepycat.je.txn.Txn
Store information about a DatabaseImpl that will have to be purged at transaction commit or abort. This handles cleanup after operations like Environment.truncateDatabase, Environment.removeDatabase. Cleanup like this is done outside the usual transaction commit or node undo processing, because the mapping tree is always auto Txn'ed to avoid deadlock and is essentially non-transactional.
