class |
KeyedProcessOperator<K,IN,OUT>
A
StreamOperator for executing KeyedProcessFunctions. |
class |
LegacyKeyedProcessOperator<K,IN,OUT>
Deprecated.
Replaced by
KeyedProcessOperator which takes KeyedProcessFunction |
| Modifier and Type | Method and Description |
|---|---|
<N> InternalTimerService<N> |
InternalTimeServiceManager.getInternalTimerService(String name,
TimerSerializer<K,N> timerSerializer,
Triggerable<K,N> triggerable) |
<K,N> InternalTimerService<N> |
AbstractStreamOperator.getInternalTimerService(String name,
org.apache.flink.api.common.typeutils.TypeSerializer<N> namespaceSerializer,
Triggerable<K,N> triggerable)
Returns a
InternalTimerService that can be used to query current processing time
and event time and to set timers. |
void |
InternalTimerServiceImpl.startTimerService(org.apache.flink.api.common.typeutils.TypeSerializer<K> keySerializer,
org.apache.flink.api.common.typeutils.TypeSerializer<N> namespaceSerializer,
Triggerable<K,N> triggerTarget)
Starts the local
InternalTimerServiceImpl by:
Setting the keySerialized and namespaceSerializer for the timers it will contain.
Setting the triggerTarget which contains the action to be performed when a timer fires.
Re-registering timers that were retrieved after recovering from a node failure, if any.
This method can be called multiple times, as long as it is called with the same serializers. |
