| Modifier and Type | Method and Description |
|---|---|
| public void | |
| public long | Returns: INVALID_LOG_INSTANT if no records have been returned yet or the scan has completed.Get the instant of the record just retrieved with getNextRecord(). |
| public LogInstant | Returns: null if no records have been returned yet or the scan has completed.Get the LogInstant for the record just retrieved with getNextRecord(). |
| public long | Returns: INVALID_LOG_INSTANT if this is not a FORWARD scan or, no record have been returned yet or the scan has completed.Get the log instant that is right after the record just retrieved with getNextRecord(). |
| public LogRecord | Returns: an object that represents the log record, return null if the scan has completed.the ArrayInputStream to put the log record input, TransactionId if non-null, only log record that equals tranId
will be returned. If null, log records are not
filtered on transaction Id. tranId, int if non-zero, only log record whose Loggable's group
value is included in the groupmask is returned.
groupmask can be a bit wise OR of many Loggable
groups. If zero, log records are not filtered on
the Loggable's group. groupmask)Get the next record in the scan and place its data in the passed in array. |
| public boolean | Returns: true if fuzzy log end found during forward scan, this happens if there was a partially written log records before the crash.
|
| public void | resetPosition(LogInstant
the log instant to reset to instant)Reset the scan to the given LogInstant so that getNextRecord get the log record AFTER the given LogInstant. |

| getLogRecordEnd | back to summary |
|---|---|
| public long getLogRecordEnd() Get the log instant that is right after the record just retrieved with getNextRecord(). Only valid for a forward scan and on a successful retrieval.

| getNextRecord | back to summary |
|---|---|
| public LogRecord getNextRecord(ArrayInputStream input, TransactionId tranId, int groupmask) throws StandardException, IOException Get the next record in the scan and place its data in the passed in array. The scan is advanced to the next log record. If the input array is of insufficient size, getNextRecord must expand the array to accomodate the log record. User can optionally pass in a transaction Id and a group mask. If provided, only log record that matches the transaction Id and the group mask is returned.
