IsEmpty | When overriden in a derived class, gets a value that indicates whether the internal state of the operator is empty. When true, the StreamInsight query engine may discard the operator instance to minimize memory utilization. |
|
NextCti | When overridden in a derived class, gets the next point in time at which the operator will be asked to process a CTI event. If the value is null, or less than or equal to the sync time of the last processed event, then no CTI events will be passed to the ProcessEvent method. |
