      • context

        public Context context()
        Description copied from interface: ContextSupport
        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.

        Specified by:
        context in interface ContextSupport
        Returns:
        the context, must not be null.
