- Method Detail
  - currentProcessingTime
```
long currentProcessingTime()
```
    Returns the current processing time.
  - currentWatermark
```
long currentWatermark()
```
    Returns the current event-time watermark.
  - initializeWatermark
```
void initializeWatermark(long watermark)
```
    Initialize watermark after restore.
  - registerProcessingTimeTimer
```
void registerProcessingTimeTimer(N namespace,
                                 long time)
```
    Registers a timer to be fired when processing time passes the given time. The namespace you pass here will be provided when the timer fires.
  - deleteProcessingTimeTimer
```
void deleteProcessingTimeTimer(N namespace,
                               long time)
```
    Deletes the timer for the given key and namespace.
  - registerEventTimeTimer
```
void registerEventTimeTimer(N namespace,
                            long time)
```
    Registers a timer to be fired when event time watermark passes the given time. The namespace you pass here will be provided when the timer fires.
  - deleteEventTimeTimer
```
void deleteEventTimeTimer(N namespace,
                          long time)
```
    Deletes the timer for the given key and namespace.
  - forEachEventTimeTimer
```
void forEachEventTimeTimer(org.apache.flink.util.function.BiConsumerWithException<N,Long,Exception> consumer)
                    throws Exception
```
    Performs an action for each registered timer. The timer service will set the key context for the timers key before invoking the action.
    
    Throws:
    
    Exception
  - forEachProcessingTimeTimer
```
void forEachProcessingTimeTimer(org.apache.flink.util.function.BiConsumerWithException<N,Long,Exception> consumer)
                         throws Exception
```
    Performs an action for each registered timer. The timer service will set the key context for the timers key before invoking the action.
    
    Throws:
    
    Exception
