OpenModelThreadGroup()
```
- Method Detail
  - getSchema
```
 OpenModelThreadGroupSchema getSchema()
```
  - getProps
```
 PropertiesAccessor<OpenModelThreadGroup, OpenModelThreadGroupSchema> getProps()
```
    Allows type-safe accessors to the properties of the current element. Note: when overriding the method, ensure you emit wildcards. For instance: JMeterElementInstance<? extends TestPlanClass> getProps() { return ... }
  - getScheduleString
```
 final String getScheduleString()
```
    Schedule expression (see ThreadSchedule).
  - setScheduleString
```
 final Unit setScheduleString(String scheduleString)
```
    Schedule expression (see ThreadSchedule).
  - getRandomSeed
```
 final Long getRandomSeed()
```
  - getRandomSeedString
```
 final String getRandomSeedString()
```
    Random seed for building reproducible schedules. 0 means random seed.
  - setRandomSeedString
```
 final Unit setRandomSeedString(String randomSeedString)
```
    Random seed for building reproducible schedules. 0 means random seed.
  - recoverRunningVersion
```
 Unit recoverRunningVersion()
```
    Tells the test element to return to the state it was in when setRunningVersion(true) was called.
  - start
```
 Unit start(Integer threadGroupIndex, ListenerNotifier notifier, ListedHashTree threadGroupTree, StandardJMeterEngine engine)
```
    Start the ThreadGroup
  - threadFinished
```
 Unit threadFinished(JMeterThread thread)
```
  - addNewThread
```
 JMeterThread addNewThread(Integer delay, StandardJMeterEngine engine)
```
    Add a new JMeterThread to this ThreadGroup for engine
    
    Returns:
    
    JMeterThread
  - stopThread
```
 Boolean stopThread(String threadName, Boolean now)
```
    Hard or graceful stop depending on now flag
    
    Returns:
    
    boolean true if stop succeeded
  - numberOfActiveThreads
```
 Integer numberOfActiveThreads()
```
    Returns:
    
    int number of active threads
  - verifyThreadsStopped
```
 Boolean verifyThreadsStopped()
```
    Returns:
    
    true if threads were correctly stopped
  - waitThreadsStopped
```
 Unit waitThreadsStopped()
```
    Wait for all Group Threads to stop after a graceful stop
  - stop
```
 Unit stop()
```
    This gracefully stops threads of Group
  - tellThreadsToStop
```
 Unit tellThreadsToStop()
```
    This immediately stop threads of Group by interrupting them. It differs from stop by being a hard stop
