Method Detail
-
compute
protected String compute()
-
getReferenceKey
public String getReferenceKey()
Return the name of your function. Convention is to prepend "__" to the name (ie "__regexFunction")- Specified by:
getReferenceKey
in interfaceFunction
- Specified by:
getReferenceKey
in classAbstractFunction
- Returns:
- The name of the funtion
- See Also:
Function.getReferenceKey()
-
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 interfaceFunction
- Specified by:
execute
in classAbstractFunction
- Parameters:
previousResult
- The previousSampleResult
currentSampler
- The currentSampler
- 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)
-
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 interfaceFunction
- Specified by:
setParameters
in classAbstractFunction
- 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)
-
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
