Parameters:

targets - of the broadcast

requestMessage - to be broadcast

threadPool - used to issue message in parallel

Returns:

the CompletionService representing the futures generated by the broadcast

checkFutures

public static void checkFutures(Utils.FutureTrackingCompService<TextProtocol.MessageExchange> compService,
                                long futureTimeout,
                                TimeUnit unit,
                                Logger logger,
                                RepImpl envImpl,
                                Formatter formatter)

Utility to wait for completion of futures in unit tests

Parameters:

compService - the futures to wait for

logger - used to report any error messages
