|
Constructs a ManualTimekeeper with its clock at the epoch. |
Advance the timekeeper's clock to (now() + dur). All futures with target time points less than or equal to (now() + dur) are fulfilled after the call to advance() returns |
|
Advance the timekeeper's clock at least enough to release the next pending event. |
|
|
|
Unsafe version of after that returns an inline Future. Any work added to this future will run inline on the Timekeeper's thread. This can potentially cause problems with timing. |
|
Returns a future that will complete at the requested time. |
|
Unsafe version of at that returns an inline Future. Any work added to this future will run inline on the Timekeeper's thread. This can potentially cause problems with timing. |
|
Returns the current clock value in the timekeeper. This is advanced only when someone calls advance() |
|
Returns the number of futures that are pending and have not yet been fulfilled |
