      default R apply(T t, U u, BiFunction<String,Exception,RuntimeException> exceptionWrapper)
      Applies this function to the given argument, wrapping any thrown checked exceptions using the given exceptionWrapper.
      Parameters:
      t - the first function argument
      u - the second function argument
      exceptionWrapper - BiFunction that wraps the given message and checked exception into a runtime exception
      Returns:
      a result

    • throwing

      default ThrowingBiFunction<T,U,R> throwing(BiFunction<String,Exception,RuntimeException> exceptionWrapper)
