public static void saveHistogram(org.HdrHistogram.Histogram histogram,
                                 String filename)
                          throws IOException

Save a Histogram to a file.

Throws:

IOException

makeResponse

public static Messages.SimpleResponse makeResponse(Messages.SimpleRequest request)

Construct a Messages.SimpleResponse for the given request.

makeRequest

public static Messages.SimpleRequest makeRequest(Messages.PayloadType payloadType,
                                                 int reqLength,

Construct a Messages.SimpleRequest with the specified dimensions.

pickUnusedPort

public static int pickUnusedPort()

Picks a port that is not used right at this moment. Warning: Not thread safe. May see "BindException: Address already in use: bind" if using the returned port to create a new server socket when other threads/processes are concurrently creating new sockets without a specific port.
