public class ClientThread

extends java.lang.Thread

Thread that manages the interaction with the remote service. It is required to allow commands to be issued to the remote services in parallel. This threads prevent the main thread of execution to be blocked by the remote calls to the remote services. A synchronization mechanism to issue and access commands is provided by ThreadSynchronizer.

Constructor Detail

ClientThread

public ClientThread(ThreadSynchronizer synchr,
 net.jini.core.lookup.ServiceItem serv)

Construct a ClientThread with a given ThreadSynchronizer and a given service.

Parameters:

synchr - A ThreadSynchronizer.

serv - The service corresponding to the remote service that the Client Thread represents.

Method Detail

getService

public net.jini.core.lookup.ServiceItem getService()

Return the service that this ClientThread controls.

Returns:

A ServiceItem corresponding to the service this Client Thread is managing remotely.

---

run

public void run()

Runs the thread. The thread blocks until it gets a command. When a command is fetched, the service performs remotely the method corresponding to the given command. Once the task is performed, the thread is set to ready in the synchronizer. This is performed until de command is exit.

---

setIterationCount

public void setIterationCount(int iterationC)

Specify the number of times that the iteration command is to be performed. We assume that this will be set correctly before iterate is called.

Parameters:

iterationC - Number of times the iteration has to be performed.
