getDeletedDupKey

public byte[] getDeletedDupKey()

getDatabaseId

public DatabaseId getDatabaseId()

isDupRootDeletion

public boolean isDupRootDeletion()
Returns true if we are certain that this log entry reflects deletion of a DIN root. Returns false if it may or may not be a DIN root. [#18663]


getLogSize

public int getLogSize()
Specified by:
getLogSize in interface Loggable
Returns:
number of bytes used to store this object.
See Also:
Loggable.getLogSize()

writeToLog

public void writeToLog(ByteBuffer logBuffer)
Description copied from interface: Loggable
Serialize this object into the buffer.

Specified by:
writeToLog in interface Loggable
Parameters:
logBuffer - is the destination buffer
See Also:
Loggable.writeToLog(java.nio.ByteBuffer)

readFromLog

public void readFromLog(ByteBuffer itemBuffer,
                        int entryVersion)
Description copied from interface: Loggable
Initialize this object from the data in itemBuf.

Specified by:
readFromLog in interface Loggable
See Also:
Loggable.readFromLog(java.nio.ByteBuffer, int)

dumpLog

public void dumpLog(StringBuilder sb,
                    boolean verbose)
Description copied from interface: Loggable
Write the object into the string buffer for log dumping. Each object should be dumped without indentation or new lines and should be valid XML.

getTransactionId

public long getTransactionId()
Specified by:
getTransactionId in interface Loggable
Returns:
the transaction id embedded within this loggable object. Objects that have no transaction id should return 0.
See Also:
Loggable.getTransactionId()

logicalEquals

public boolean logicalEquals(Loggable other)
Specified by:
logicalEquals in interface Loggable
Returns:
true if these two loggable items are logically the same. Used for replication testing.
See Also:
Always return false, this item should never be compared.
