Method Detail

digest

public static void digest(RowIterator iterator,
                          java.security.MessageDigest digest)

emptyIterator

public static RowIterator emptyIterator(CFMetaData cfm,
                                        DecoratedKey partitionKey,
                                        boolean isReverseOrder)

loggingIterator

public static RowIterator loggingIterator(RowIterator iterator,
                                          java.lang.String id)

Wraps the provided iterator so it logs the returned rows for debugging purposes.

Note that this is only meant for debugging as this can log a very large amount of logging at INFO.
