Class DeletedDupLNLogEntry

java.lang.Object
  com.sleepycat.je.log.entry.LNLogEntry
      com.sleepycat.je.log.entry.DeletedDupLNLogEntry

All Implemented Interfaces:

LogEntry, NodeLogEntry, LoggableObject, LogWritable, Cloneable

public class DeletedDupLNLogEntry
extends LNLogEntry

DupDeletedLNEntry encapsulates a deleted dupe LN entry. This contains all the regular transactional LN log entry fields and an extra key, which is the nulled out data field of the LN (which becomes the key in the duplicate tree.

Constructor Summary

DeletedDupLNLogEntry(boolean isTransactional)
Constructor to read an entry.

DeletedDupLNLogEntry(LogEntryType entryType, LN ln, DatabaseId dbId, byte[] key, byte[] dataAsKey, long abortLsn, boolean abortKnownDeleted, Txn txn)
Constructor to make an object that can write this entry.

Method Summary

StringBuffer	dumpEntry(StringBuffer sb, boolean verbose) Extends super class to dump out extra key.
byte[]	getDupKey() Get the data-as-key out of the entry.
int	getLogSize() Extend super class to add in extra key.
void	readEntry(ByteBuffer entryBuffer, int entrySize, byte entryTypeVersion, boolean readFullItem) Extends its super class to read in the extra dup key.
void	writeToLog(ByteBuffer destBuffer) Serialize this object into the buffer.
