ParkNParkClient

public ParkNParkClient(ORB orb,
                       int numClients,
                       int numServers,
                       int interRequestTime,
                       int replySize,
                       boolean neverGiveUp,
                       int getLotsModeCount,
                       int detectionTimeout,
                       int recoveryTimeout)

Creates a new ParkNParkClient instance that will use the given ORB to communicate with the server

Parameters:

orb - The ORB to communicate with the server on

numClients - The number of clients in the current test

numServers - The number of servers in the current test

interRequestTime - The delay between each invocation, which is used when constructing the log file names

replySize - The size of the server's replies, which is used when constructing the log file names

neverGiveUp - When true, the client will never give up its attempt to contact the server, even if no primary is registered

detectionTimeout - The wait timeout to use during fault detections

recoveryTimeout - The wait timeout to use during fault recoveries
