          public UserParameters()

  - ### Method Detail

    - #### getNames

          public CollectionProperty getNames()

    - #### getThreadLists

          public CollectionProperty getThreadLists()

    - #### setNames

          public void setNames(Collection<?> list)

      The list of names of the variables to hold values. This list must come in the same order as the sub lists that are given to `setThreadLists(Collection)`.
      Parameters:
        `list` - The ordered list of names

    - #### setNames

          public void setNames(CollectionProperty list)

      The list of names of the variables to hold values. This list must come in the same order as the sub lists that are given to `setThreadLists(CollectionProperty)`.
      Parameters:
        `list` - The ordered list of names

    - #### setThreadLists

          public void setThreadLists(Collection<?> threadLists)

      The thread list is a list of lists. Each list within the parent list is a collection of values for a simulated user. As many different sets of values can be supplied in this fashion to cause JMeter to set different values to variables for different test threads.
      Parameters:
        `threadLists` - The list of lists of values for each user thread

    - #### setThreadLists

          public void setThreadLists(CollectionProperty threadLists)

      The thread list is a list of lists. Each list within the parent list is a collection of values for a simulated user. As many different sets of values can be supplied in this fashion to cause JMeter to set different values to variables for different test threads.
      Parameters:
        `threadLists` - The list of lists of values for each user thread

    - #### isPerIteration

          public boolean isPerIteration()

    - #### setPerIteration

          public void setPerIteration(boolean perIter)

    - #### process

          public void process()

      Specified by:
        `process` in interface `PreProcessor`

    - #### iterationStart

          public void iterationStart(LoopIterationEvent event)

      Description copied from interface: `LoopIterationListener`
      Called when a loop iteration is about to start.
      Specified by:
        `iterationStart` in interface `LoopIterationListener`
      Parameters:
        `event` - the event
      See Also:
        `LoopIterationListener.iterationStart(LoopIterationEvent)`

    - #### clone

          public Object clone()

      A new instance is created for each thread group, and the clone() method is then called to create copies for each thread in a thread group. This means that the lock object is common to all instances
      Specified by:
        `clone` in interface `TestElement`
      Overrides:
        `clone` in class `AbstractTestElement`
      See Also:
        `Object.clone()`
