Constructor Summary

Jexl2Function()

Method Summary

String	execute(SampleResult previousResult, Sampler currentSampler) N.B. execute() should be synchronized if function is operating with non-thread-safe objects (e.g. operates with files).
List<String>	getArgumentDesc() Return a list of strings briefly describing each parameter your function takes.
String	getReferenceKey() Return the name of your function.
void	setParameters(Collection<CompoundVariable> parameters) A collection of the parameters used to configure your function.
void	threadFinished() Called for each thread after all samples have been processed.
void	threadStarted() Called for each thread before starting sampling.

Method Detail

execute

public String execute(SampleResult previousResult,
                      Sampler currentSampler)
               throws InvalidVariableException

N.B. execute() should be synchronized if function is operating with non-thread-safe objects (e.g. operates with files).

JMeter ensures setParameters() happens-before execute(): setParameters is executed in main thread, and worker threads are started after that.

Specified by:

execute in interface Function

Specified by:

execute in class AbstractFunction

Throws:

InvalidVariableException

See Also:

Function.execute(SampleResult, Sampler)

getArgumentDesc

public List<String> getArgumentDesc()

Return a list of strings briefly describing each parameter your function takes. Please use JMeterUtils.getResString(resource_name) to grab a resource string. Otherwise, your help text will be difficult to internationalize. This list is not optional. If you don't wish to write help, you must at least return a List containing the correct number of blank strings, one for each argument.

Specified by:

getArgumentDesc in interface Function

getReferenceKey

public String getReferenceKey()

Return the name of your function. Convention is to prepend "__" to the name (ie "__regexFunction")

Specified by:

getReferenceKey in interface Function

Specified by:

getReferenceKey in class AbstractFunction

See Also:

Function.getReferenceKey()

setParameters

public void setParameters(Collection<CompoundVariable> parameters)
                   throws InvalidVariableException

A collection of the parameters used to configure your function. Each parameter is a CompoundVariable and can be resolved by calling the execute() method of the CompoundVariable (which should be done at execution.)

Specified by:

setParameters in interface Function

Specified by:

setParameters in class AbstractFunction

Throws:

InvalidVariableException

Note: This is always called even if no parameters are provided (versions of JMeter after 2.3.1)

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 interface ThreadListener

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 interface ThreadListener
