      public class ResultCollector
      extends AbstractListenerElement
      implements SampleListener, Clearable, Serializable, TestStateListener, Remoteable, NoThreadClone

  This class handles all saving of samples. The class must be thread-safe because it is shared between threads (NoThreadClone).
