This method needs to be implemented by the class that implement the Future API. The implementation must never throw an error, but only return either TRUE or FALSE. It should also be possible to use the method for polling the future until it is resolved (without having to wait infinitely long), e.g. `while (!resolved(future)) Sys.sleep(5)`.

### Value

A logical of the same length and dimensions as `x`. Each element is TRUE unless the corresponding element is a non-resolved future in case it is FALSE.
