Uses of TimerService in org.apache.flink.streaming.runtime.tasks

Classes in org.apache.flink.streaming.runtime.tasks that implement TimerService

Modifier and Type	Class and Description
class	SystemProcessingTimeService A TimerService which assigns as current processing time the result of calling System.currentTimeMillis() and registers timers using a ScheduledThreadPoolExecutor.
class	TestProcessingTimeService This is a TimerService and ProcessingTimeService used strictly for testing the processing time functionality.

Fields in org.apache.flink.streaming.runtime.tasks declared as TimerService

Modifier and Type	Field and Description
protected TimerService	StreamTask.systemTimerService In contrast to StreamTask.timerService we should not register any user timers here.
protected TimerService	StreamTask.timerService The internal TimerService used to define the current processing time (default = System.currentTimeMillis()) and register timers for tasks to be executed in the future.
