Examples of LNLogEntry

com.sleepycat.je.log.entry.LNLogEntry
LNLogEntry embodies all LN log entries. On disk, an LN log entry contains (pre version 6)
```
 LN databaseid key abortLsn          -- if transactional abortKnownDeleted -- if transactional txn               -- if transactional (version 6) databaseid abortLsn          -- if transactional abortKnownDeleted -- if transactional txn               -- if transactional LN key 
```
Before version 6, a non-full-item read of a log entry only retrieved the node ID. After version 6, the database id, transaction id and node ID are all available.
