      public class NotImplementedException
      extends UnsupportedOperationException

  Thrown to indicate that a block of code has not been implemented. This exception supplements `UnsupportedOperationException` by providing a more semantically rich description of the problem.

  `NotImplementedException` represents the case where the author has yet to implement the logic at this point in the program. This can act as an exception based TODO tag.

       public void foo() {
         try {
           // do something that throws an Exception
         } catch (Exception ex) {
           // don't know what to do here yet
           throw new NotImplementedException("TODO", ex);
         }
       }

  This class was originally added in Lang 2.0, but removed in 3.0.
  Since:
    3.2
