Interface Controller

All Superinterfaces:

Cloneable, TestElement

All Known Implementing Classes:

AbstractThreadGroup, ForeachController, GenericController, IfController, IncludeController, InterleaveControl, LoopController, ModuleController, OnceOnlyController, PostThreadGroup, ProxyControl, RandomController, RandomOrderController, RecordingController, RunTime, SetupThreadGroup, SwitchController, TestFragmentController, ThreadGroup, ThroughputController, TransactionController, WhileController

public interface Controller
extends TestElement

This interface is used by JMeterThread in the following manner: while (running && (sampler = controller.next()) != null)

Method Summary

void	addIterationListener(LoopIterationListener listener) Controllers have to notify listeners of when they begin an iteration through their sub-elements.
void	initialize() Called to initialize a controller at the beginning of a test iteration.
boolean	isDone() Indicates whether the Controller is done delivering Samplers for the rest of the test.
Sampler	next() Delivers the next Sampler or null
void	removeIterationListener(LoopIterationListener iterationListener) Unregister IterationListener
void	triggerEndOfLoop() Trigger end of loop condition on controller (used by Start Next Loop feature)

Method Detail

next

Sampler next()

Delivers the next Sampler or null

Returns:

org.apache.jmeter.samplers.Sampler or null

isDone

boolean isDone()

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.

Returns:

boolean

addIterationListener

void addIterationListener(LoopIterationListener listener)

Controllers have to notify listeners of when they begin an iteration through their sub-elements.

initialize

void initialize()

Called to initialize a controller at the beginning of a test iteration.

removeIterationListener

void removeIterationListener(LoopIterationListener iterationListener)

Unregister IterationListener

Parameters:

iterationListener - LoopIterationListener

triggerEndOfLoop

void triggerEndOfLoop()

Trigger end of loop condition on controller (used by Start Next Loop feature)
