resolved.Future: Check whether a future is resolved or not

Description

Check whether a future is resolved or not

Usage

## S3 method for class 'Future':
resolved(future, ...)

Arguments

future
A Future.
...
Not used

Value

  • TRUE if future is resolved and FALSE if unresolved.

Details

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 infinitly long), e.g. while (!resolved(future)) Sys.sleep(5).
