## Constructor Details

### SubscriberSampler

public SubscriberSampler()

## Method Details

### sample

public SampleResult sample()
sample method will check which client it should use and call the appropriate client specific sample method.

Specified by:
  `sample` in class `BaseJMSSampler`
Returns:
  the appropriate sample result

### threadStarted

public void threadStarted()
Initialise the thread-local variables.
Called for each thread before starting sampling. WARNING: this is called before any Config test elements are processed, so any properties they define will not have been merged in yet. See org.apache.jmeter.threads.JMeterThread#threadStarted()

Specified by:
  `threadStarted` in interface `ThreadListener`

### threadStarted

public void threadStarted(boolean wts)

### threadFinished

public void threadFinished()
Close subscriber.
Called for each thread after all samples have been processed. See org.apache.jmeter.threads.JMeterThread#threadFinished(org.apache.jmeter.engine.event.LoopIterationListener)

Specified by:
  `threadFinished` in interface `ThreadListener`

### threadFinished

public void threadFinished(boolean wts)

### interrupt

public boolean interrupt()
Handle an interrupt of the test.

Specified by:
  `interrupt` in interface `Interruptible`
Returns:
  `true` if there was an operation to interrupt.

### setClientChoice

public void setClientChoice(String choice)
Set the client choice. There are two options: ReceiveSusbscriber and OnMessageSubscriber.

Parameters:
  `choice` - the client to use. One of `RECEIVE_RSC` or `ON_MESSAGE_RSC`

### getClientChoice

public String getClientChoice()
Return the client choice.

Returns:
  the client choice, either `RECEIVE_RSC` or `ON_MESSAGE_RSC`

### getTimeout

public String getTimeout()

### getTimeoutAsLong

public long getTimeoutAsLong()

### setTimeout

public void setTimeout(String timeout)

### getDurableSubscriptionId

public String getDurableSubscriptionId()

### getClientId

public String getClientId()

Returns:
  JMS Client ID

### getJmsSelector

public String getJmsSelector()

Returns:
  JMS selector

### setDurableSubscriptionId

public void setDurableSubscriptionId(String durableSubscriptionId)

### setClientID

public void setClientID(String clientId)

Parameters:
  `clientId` - JMS CLient id

### setJmsSelector

public void setJmsSelector(String jmsSelector)

Parameters:
  `jmsSelector` - JMS Selector

### getSeparator

public String getSeparator()

Returns:
  Separator for sampler results

### setSeparator

public void setSeparator(String text)
Separator for sampler results

Parameters:
  `text` - separator to use for sampler results

### isStopBetweenSamples

public boolean isStopBetweenSamples()

### setStopBetweenSamples

public void setStopBetweenSamples(boolean selected)

### setPauseBetweenErrors

public void setPauseBetweenErrors(String pause)

### getPauseBetweenErrors

public String getPauseBetweenErrors()

### getPauseBetweenErrorsAsLong

public long getPauseBetweenErrorsAsLong()

### testEnded

public void testEnded()

Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:
  `testEnded` in interface `TestStateListener`
See Also:
  - `StandardJMeterEngine.stopTest()`

### testEnded

public void testEnded(String host)

Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:
  `testEnded` in interface `TestStateListener`
Parameters:
  `host` - name of host
See Also:
  - `StandardJMeterEngine.stopTest()`

### testStarted

public void testStarted()

Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:
  `testStarted` in interface `TestStateListener`
See Also:
  - `StandardJMeterEngine.run()`

### testStarted

public void testStarted(String host)

Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:
  `testStarted` in interface `TestStateListener`
Parameters:
  `host` - name of host

  - `StandardJMeterEngine.run()`
