  * This class is used to create and call appropriate methods on the C++ Task Runner to initialize,
  * execute and terminate any MediaPipe task. 
  * 
- * An instance of the newly created C++ task runner will
- * be stored until this class is destroyed. When methods are called for processing (performing
- * inference), closing etc., on this class, internally the appropriate methods will be called on the
- * C++ task runner instance to execute the appropriate actions. For each type of task, a subclass of
- * this class must be defined to add any additional functionality. For eg:, vision tasks must create
- * an `MPPVisionTaskRunner` and provide additional functionality. An instance of
- * `MPPVisionTaskRunner` can in turn be used by the each vision task for creation and execution of
- * the task. Please see the documentation for the C++ Task Runner for more details on how the taks
- * runner operates.
