Method Summary

String	execute(SampleResult previousResult, Sampler currentSampler) N.B. setParameters() and execute() are called from different threads, so both must be synchronized unless there are no parameters to save
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) N.B. setParameters() and execute() are called from different threads, so both must be synchronized unless there are no parameters to save

Method Detail

execute

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

N.B. setParameters() and execute() are called from different threads, so both must be synchronized unless there are no parameters to save

Specified by:

execute in interface Function

Specified by:

execute in class AbstractFunction

Throws:

InvalidVariableException

See Also:

Function.execute(SampleResult, Sampler)

setParameters

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

N.B. setParameters() and execute() are called from different threads, so both must be synchronized unless there are no parameters to save

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)

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()

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.
