TimerFunction

All Known Implementing Classes:

```
public interface Timer
extends TimerFunction
```
Stateful TimerFunction to invoke at a scheduled time, with lifecycle callbacks, and a TimerContext for self-management. Use Schedule.setTimer(long, TimerFunction) to schedule a new Timer for execution.

- Method Detail
  - timerContext
```
TimerContext timerContext()
```
