|---|---|
| int | blockForWrites()Flushes all keyspaces associated with this replayer in parallel, blocking until their flushes are complete. | 
| static CommitLogReplayer | construct(CommitLog commitLog) | 
| static CommitLogPosition | firstNotCovered(java.util.Collection<IntervalSet<CommitLogPosition>> ranges)Find the earliest commit log position that is not covered by the known flushed ranges for some table. | 
| void | handleMutation(Mutation m,
              int size,
              int entryLocation,
              CommitLogDescriptor desc)Process a deserialized mutation | 
| void | handleUnrecoverableError(CommitLogReadHandler.CommitLogReadException exception)The logic for whether or not we throw on an error is identical for the replayer between recoverable or non. | 
| static IntervalSet<CommitLogPosition> | persistedIntervals(java.lang.Iterable<SSTableReader> onDisk,
                  CommitLogPosition truncatedAt)A set of known safe-to-discard commit log replay positions, based on
 the range covered by on disk sstables and those prior to the most recent truncation record | 
| protected boolean | pointInTimeExceeded(Mutation fm) | 
| void | replayFiles(java.io.File[] clogs) | 
| void | replayPath(java.io.File file,
          boolean tolerateTruncation) | 
| boolean | shouldSkipSegmentOnError(CommitLogReadHandler.CommitLogReadException exception)Handle an error during segment read, signaling whether or not you want the reader to skip the remainder of the
 current segment on error. |
