Method Summary

long	getPrevFullLsn()
boolean	isBINDelta()

Method Detail

getIN

IN getIN(DatabaseImpl dbImpl)
  throws DatabaseException

Currently used by recovery only. For an OldBINDeltaEntry it merges the delta with the last full BIN and returns the new full BIN. For a new BINDeltaLogEntry, it just returns the delta. And for an INLogEntry it just returns the (full) IN.

Throws:

DatabaseException

isBINDelta

boolean isBINDelta()

getDbId

DatabaseId getDbId()

Returns:

the database id held within this log entry.

getPrevFullLsn

long getPrevFullLsn()

Returns:

the LSN of the prior full version of this node, or NULL_LSN if no prior full version. Used for counting the prior version as obsolete. If the offset of the LSN is zero, only the file number is known because we read a version 1 log entry.

getPrevDeltaLsn

long getPrevDeltaLsn()

Returns:

the LSN of the prior delta version of this node, or NULL_LSN if the prior version is a full version. Used for counting the prior version as obsolete. If the offset of the LSN is zero, only the file number is known because we read a version 1 log entry.
