public class SyncTimer extends AbstractTestElement implements Timer, Serializable, TestBean, TestStateListener, ThreadListener
The purpose of the SyncTimer is to block threads until X number of threads have been blocked, and then they are all released at once. A SyncTimer can thus create large instant loads at various points of the test plan.- See Also:

Method Detail
-
getGroupSize
public int getGroupSize()
- Returns:
- Returns the numThreads.
-
setGroupSize
public void setGroupSize(int numThreads)
- Parameters:
numThreads
- The numThreads to set.
-
delay
public long delay()
This method is called after a sampling process is done to know how much time the sampling thread has to wait until sampling again.
-
clone
public Object clone()
We have to control the cloning process because we need some cross-thread communication if our synctimers are to be able to determine when to block and when to release.- Specified by:
clone
in interfaceTestElement
- Overrides:
clone
in classAbstractTestElement
-
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 interfaceTestStateListener
- See Also:
StandardJMeterEngine.stopTest()
-
testEnded
public void testEnded(String host)
Reset timerCounter- Specified by:
testEnded
in interfaceTestStateListener
- 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 interfaceTestStateListener
- See Also:
StandardJMeterEngine.run()
-
testStarted
public void testStarted(String host)
Reset timerCounter- Specified by:
testStarted
in interfaceTestStateListener
- Parameters:
host
- name of host- See Also:
StandardJMeterEngine.run()
-
threadStarted
public void threadStarted()
Description copied from interface:ThreadListener
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.- Specified by:
threadStarted
in interfaceThreadListener
- See Also:
JMeterThread.threadStarted()
-
threadFinished
public void threadFinished()
Description copied from interface:ThreadListener
Called for each thread after all samples have been processed.- Specified by:
threadFinished
in interfaceThreadListener
- See Also:
JMeterThread.threadFinished(org.apache.jmeter.engine.event.LoopIterationListener)
-
getTimeoutInMs
public long getTimeoutInMs()
- Returns:
- the timeoutInMs
-
setTimeoutInMs
public void setTimeoutInMs(long timeoutInMs)
- Parameters:
timeoutInMs
- the timeoutInMs to set
