CompoundVariable

public CompoundVariable(String parameters)
Method Detail

execute

public String execute()

getRawParameters

public String getRawParameters()
Allows the retrieval of the original String prior to it being compiled.

Returns:
String

execute

public String execute(SampleResult previousResult,
                      Sampler currentSampler)
Given the previous SampleResult and the current Sampler, return a string to use as a replacement value for the function call. Assume "setParameter" was previously called. This method must be threadsafe - multiple threads will be using the same object.

Specified by:
execute in interface Function

getFunction

public CompoundVariable getFunction()

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

clear

public void clear()

setParameters

public void setParameters(String parameters)
                   throws InvalidVariableException
Throws:
InvalidVariableException

getFunctionClass

public static Class<? extends Function> getFunctionClass(String className)

getFunctionNames

public static String[] getFunctionNames()

hasFunction

public boolean hasFunction()

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

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
Throws:
InvalidVariableException
