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. |
|
BINDelta(SizeofMarker marker)
For Sizeof. |
Method Summary | |

getPrevDeltaLsn()
|
byte[] |
getSearchKey()
Returns a key that can be used to find the BIN associated with this delta. |
long |
getTransactionId()
|
boolean |
logicalEquals(Loggable other)
|
void |
readFromLog(ByteBuffer itemBuffer,
int entryVersion)
Initialize this object from the data in itemBuf. |
BIN |
reconstituteBIN(DatabaseImpl dbImpl)
Create a BIN by fetching the full version and applying the deltas. |
void |
reconstituteBIN(DatabaseImpl dbImpl,
BIN fullBIN)
Given a full version BIN, apply the deltas. |
