## org.apache.jmeter.protocol.jms.client
Class ClientPool

    java.lang.Object
      org.apache.jmeter.protocol.jms.client.ClientPool

    public class ClientPool

extends Object

ClientPool holds the client instances in an ArrayList. The main purpose of this is to make it easier to clean up all the instances at the end of a test. If we didn't do this, threads might become zombie. N.B. This class needs to be fully synchronized as it is called from sample threads and the thread that runs testEnded() methods.

Method Detail

### addClient

    public static void addClient(Closeable client)

  Add a ReceiveClient to the ClientPool. This is so that we can make sure to close all clients and make sure all threads are destroyed.

  Parameters:
    `client` -

### clearClient

    public static void clearClient()

  Clear all the clients created by either Publish or Subscribe sampler. We need to do this to make sure all the threads creatd during the test are destroyed and cleaned up. In some cases, the client provided by the manufacturer of the JMS server may have bugs and some threads may become zombie. In those cases, it is not the responsibility of JMeter for those bugs.

### put

    public static void put(Object key,
                           Object client)

### get

    public static Object get(Object key)
