    • context

      default Context context()
      Provide a context.

      Since calls to this method shall only be triggered when a Mutiny pipeline uses a withContext operator, there is no need in general for caching the context value in a field of the implementing class. Exceptions include operators that have cross-subscriber semantics such as memoizers or broadcasters.

      This method is expected to be called once per withContext operator.

      Returns:
      the context, must not be null.
