java.lang.Objectcom.sleepycat.db.LogSequenceNumber
public class LogSequenceNumber
The LogSequenceNumber object is a log sequence number which specifies a unique location in a log file. A LogSequenceNumber consists of two unsigned 32-bit integers -- one specifies the log file number, and the other specifies the offset in the log file.
| Constructor Summary | |
|---|---|
| LogSequenceNumber()Construct an uninitialized LogSequenceNumber. | |
| LogSequenceNumber(int file,
                  int offset)Construct a LogSequenceNumber with the specified file and offset. | |
| Method Summary | |
|---|---|
| static int | compare(LogSequenceNumber lsn1,
        LogSequenceNumber lsn2)Compare two LogSequenceNumber objects. | 
|  int | getFile()Return the file number component of the LogSequenceNumber. | 
|  int | getOffset()Return the file offset component of the LogSequenceNumber. |

public LogSequenceNumber(int file,
                         int offset)
file - The log file number.
    offset - The log file offset.public LogSequenceNumber()

public int getFile()
public int getOffset()
public static int compare(LogSequenceNumber lsn1,
                          LogSequenceNumber lsn2)
This method returns 0 if the two LogSequenceNumber objects are equal, 1 if lsn0 is greater than lsn1, and -1 if lsn0 is less than lsn1.
lsn1 - The first LogSequenceNumber object to be compared.
    lsn2 - The second LogSequenceNumber object to be compared.
