java.lang.Objectcom.sleepycat.je.tree.BINDelta
public class BINDelta
BINDelta contains the information needed to create a partial (delta) BIN log entry. It also knows how to combine a full BIN log entry and a delta to generate a new BIN.
Constructor Summary | |
---|---|
BINDelta()
For instantiating from the log. |
|
BINDelta(BIN bin)
Read a BIN and create the deltas. |
Method Summary | |
---|---|
boolean |
countAsObsoleteWhenLogged()
Returns true if this item should be counted as obsoleted when logged. |
void |
dumpLog(StringBuffer sb,
boolean verbose)
Write the object into the string buffer for log dumping. |
DatabaseId |
getDbId()
|
long |
getLastFullLsn()
|
int |
getLogSize()
|
LogEntryType |
getLogType()
All objects that are reponsible for a generating a type of log entry must implement this. |
(package private) int |
getNumDeltas()
|
long |
getTransactionId()
|
boolean |
logEntryIsTransactional()
|
boolean |
marshallOutsideWriteLatch()
Return true if this item can be marshalled outside the log write latch. |
void |
postLogWork(long justLoggedLsn)
Do any processing we need to do after logging, while under the logging latch. |
void |
readFromLog(ByteBuffer itemBuffer,
byte entryTypeVersion)
Initialize this object from the data in itemBuf. |
BIN |
reconstituteBIN(EnvironmentImpl env)
Create a BIN by starting with the full version and applying the deltas. |
void |
writeToLog(ByteBuffer logBuffer)
Serialize this object into the buffer. |
