  Description
  Controller
  This interface is used by JMeterThread in the following manner:
  CriticalSectionController
  This is a Critical Section Controller; it will execute the set of statements (samplers/controllers, etc) under named lock.
  ForeachController
  ForeachController that iterates over a list of variables named XXXX_NN stored in `JMeterVariables` where NN is a number starting from 1 to number of occurrences.
  GenericController
  This class is the basis for all the controllers.
  IfController
  This is a Conditional Controller; it will execute the set of statements (samplers/controllers, etc) while the 'condition' is true.
  IncludeController
  InterleaveControl
  Alternate among each of the children controllers or samplers for each loop iteration
  IteratingController
  Identify controller that does iterations
  LoopController
  Class that implements the Loop Controller, ie iterate infinitely or a configured number of times
  ModuleController
  The goal of ModuleController is to add modularity to JMeter.
  NextIsNullException
  Used by the Generic and Interleave controllers to signal the end of their samples
  OnceOnlyController
  Controller to run its children once per cycle.
  RandomController
  Controller that rans randomly one of it's children on each iteration
  RandomOrderController
  A controller that runs its children each at most once, but in a random order.
  ReplaceableController
  This interface represents a controller that gets replaced during the compilation phase of test execution in an arbitrary way.
  RunTime
  Runtime Controller that runs its children until configured Runtime(s) is exceeded
  SwitchController
  Implements a controller which selects at most one of its children based on the condition value, which may be a number or a string.
  TestFragmentController
  ThroughputController
  This class represents a controller that can control the number of times that it is executed, either by the total number of times the user wants the controller executed (BYNUMBER) or by the percentage of time it is called (BYPERCENT) The current implementation executes the first N samples (BYNUMBER) or the last N% of samples (BYPERCENT).
  TransactionController
  Transaction Controller to measure transaction times There are two different modes for the controller: - generate additional total sample after nested samples (as in JMeter 2.2) - generate parent sampler containing the nested samples
  TransactionSampler
  Transaction Sampler class to measure transaction times (not exposed as a GUI class, as it is only used internally by TransactionController in Generate Parent sample mode)
  WhileController
