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

Parameters:

previousResult - The previous SampleResult

currentSampler - The current Sampler

Returns:

The replacement value, which was generated by the function

Throws:

InvalidVariableException - - when the variables for the function call can't be evaluated

See Also:

Function.execute(SampleResult, Sampler)

log_info

public void log_info(String s)

setParameters

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

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

Specified by:

setParameters in interface Function

Specified by:

setParameters in class AbstractFunction

Parameters:

parameters - The parameters for the function call

Throws:

InvalidVariableException - - when the variables for the function call can't be evaluated

See Also:

Function.setParameters(Collection)

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

Returns:

The name of the funtion

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.

Returns:

List with brief descriptions for each parameter the function takes
