# Class ThroughputController

java.lang.Object
org.apache.jmeter.testelement.AbstractTestElement
org.apache.jmeter.control.GenericController
org.apache.jmeter.control.ThroughputController

All Implemented Interfaces:
  `Serializable`, `Cloneable`, `Controller`, `LoopIterationListener`, `Searchable`, `org.apache.jmeter.testelement.TestElement`, `TestStateListener`, `TestCompilerHelper`

public class ThroughputController extends GenericController implements Serializable, LoopIterationListener, TestStateListener
This class represents a controller that can control the number of times that it is executed, either by the total number of times the user wants the controller executed (BYNUMBER) or by the percentage of time it is called (BYPERCENT) The current implementation executes the first N samples (BYNUMBER) or the last N% of samples (BYPERCENT).

### next

public Sampler next()
Description copied from class: `GenericController`

Determines the next sampler to be processed.

If `GenericController.isDone()` is `true`, returns null.

Gets the list element using current pointer. If this is `null`, calls `GenericController.nextIsNull()`.

If the list element is a `Sampler`, calls `GenericController.nextIsASampler(Sampler)`, otherwise calls `GenericController.nextIsAController(Controller)`

If any of the called methods throws `NextIsNullException`, returns `null`, otherwise the value obtained above is returned.

Specified by:
  `next` in interface `Controller`
Overrides:
  `next` in class `GenericController`
Returns:
  the next sampler or `null`

### isDone

public boolean isDone()
Description copied from interface: `Controller`
Indicates whether the Controller is done delivering Samplers for the rest of the test. When the top-level controller returns true to JMeterThread, the thread is complete.

Specified by:
  `isDone` in interface `Controller`
Overrides:
  `isDone` in class `GenericController`
Returns:
  boolean
See Also:
  - `Controller.isDone()`

### clone

public Object clone()

Specified by:
  `clone` in interface `org.apache.jmeter.testelement.TestElement`
Overrides:
  `clone` in class `AbstractTestElement`

### iterationStart

public void iterationStart(LoopIterationEvent iterEvent)
Description copied from interface: `LoopIterationListener`
Called when a loop iteration is about to start.

Specified by:
  `iterationStart` in interface `LoopIterationListener`
Parameters:
  `iterEvent` - the event

### testStarted

public void testStarted()
Description copied from interface: `TestStateListener`

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)
Description copied from interface: `TestStateListener`

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
See Also:
  - `StandardJMeterEngine.run()`

### testEnded

public void testEnded()
Description copied from interface: `TestStateListener`

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)
Description copied from interface: `TestStateListener`

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()`

### readResolve

protected Object readResolve()

Overrides:
  `readResolve` in class `GenericController`
