Creates a AsyncStateRecordsCombiner that can combine buffered data into async states.

Parameters:

runtimeContext - the current RuntimeContext

timerService - the service to register event-time and processing-time timers

windowState - the window state to flush buffered data into.

isEventTime - indicates whether the operator works in event-time or processing-time mode, used for register corresponding timers.

Throws:

Exception
