Constant Field Values

Constructor Detail

JavaSampler

public JavaSampler()

Create a JavaSampler.

Method Detail

clone

public Object clone()

Specified by:

clone in interface TestElement

Overrides:

clone in class AbstractTestElement

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: 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()

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 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()

applies

public boolean applies(ConfigTestElement configElement)

Description copied from class: AbstractSampler

Does configElement apply to Sampler

Specified by:

applies in interface ConfigMergabilityIndicator

Overrides:

applies in class AbstractSampler

Parameters:

configElement - ConfigTestElement

Returns:

boolean

AbstractSampler.applies(org.apache.jmeter.config.ConfigTestElement)
