Timer (SmallRye Fault Tolerance: Core 6.3.0 API)

All Known Implementing Classes:

ThreadTimer
```
public interface Timer
```
Timer allows scheduling tasks for execution in the future. Tasks are always executed on a well-defined Executor. Timer implementations must have a default executor for tasks scheduled using schedule(long, Runnable). Tasks scheduled using schedule(long, Runnable, Executor) are executed on the given executor.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`countScheduledTasks()`	Returns the number of tasks that are currently scheduled for execution by the timer.
`TimerTask`	`schedule(long delayInMillis, Runnable task)`	Schedules the `task` to be executed in `delayInMillis` on this timer's default `Executor`.
`TimerTask`	`schedule(long delayInMillis, Runnable task, Executor executor)`	Schedules the `task` to be executed in `delayInMillis` on given `executor`.
`void`	`shutdown()`	Shuts down this timer.

- Method Detail
  - schedule
```
TimerTask schedule(long delayInMillis,
                   Runnable task)
```
    Schedules the task to be executed in delayInMillis on this timer's default Executor.
    Equivalent to schedule(delayInMillis, task, null).
  - schedule
```
TimerTask schedule(long delayInMillis,
                   Runnable task,
                   Executor executor)
```
    Schedules the task to be executed in delayInMillis on given executor. If executor is null, this timer's default executor is used.
  - countScheduledTasks
```
int countScheduledTasks()
```
    Returns the number of tasks that are currently scheduled for execution by the timer. Finished tasks and tasks that are already running are not included.
    
    Returns:
    
    the number of currently scheduled tasks
  - shutdown
```
void shutdown()
       throws InterruptedException
```
    Shuts down this timer. Returns after all internal resources of this timer are shut down.
    
    Throws:
    
    InterruptedException
