Constant Field Values

ARGUMENTS

public static final String ARGUMENTS

Property key representing the arguments for the JavaSamplerClient.

Constant Field Values

Constructor Detail

JavaSampler

public JavaSampler()

Create a JavaSampler.

Method Detail

setArguments

public void setArguments(Arguments args)

Set the arguments (parameters) for the JavaSamplerClient to be executed with.

Parameters:

args - the new arguments. These replace any existing arguments.

getArguments

public Arguments getArguments()

Get the arguments (parameters) for the JavaSamplerClient to be executed with.

Returns:

the arguments

setClassname

public void setClassname(String classname)

Sets the Classname attribute of the JavaConfig object

Parameters:

classname - the new Classname value

getClassname

public String getClassname()

Gets the Classname attribute of the JavaConfig object

Returns:

the Classname value

sample

public SampleResult sample(Entry entry)

Performs a test sample. The sample() method retrieves the reference to the Java client and calls its runTest() method.

Specified by:

sample in interface Sampler

Parameters:

entry - the Entry for this sample

Returns:

test SampleResult

See Also:

JavaSamplerClient.runTest(JavaSamplerContext)

testStarted

public void testStarted()

Description copied from interface: TestListener

Called just before the start of the test Note that not all the test variables will have been set up at this point.

Specified by:

testStarted in interface TestListener

See Also:

StandardJMeterEngine.run()

testStarted

public void testStarted(String host)

Specified by:

testStarted in interface TestListener

testEnded

public void testEnded()

Method called at the end of the test. This is called only on one instance of JavaSampler. This method will loop through all of the other JavaSamplers which have been registered (automatically in the constructor) and notify them that the test has ended, allowing the JavaSamplerClients to cleanup.

Specified by:

testEnded in interface TestListener

See Also:

StandardJMeterEngine.stopTest()

testEnded

public void testEnded(String host)

Specified by:

testEnded in interface TestListener

testIterationStart

public void testIterationStart(LoopIterationEvent event)

Description copied from interface: TestListener

Each time through a Thread Group's test script, an iteration event is fired.

Specified by:

testIterationStart in interface TestListener

Parameters:

event -
