Syntax
[DataContractAttribute]
public abstract class CepEdgeStreamOperator<TInputPayload, TOutputPayload> : CepStreamOperator<EdgeEvent<TInputPayload>, TInputPayload, TOutputPayload>
Type Parameters
- TInputPayload
The type of the input event payload.
- TOutputPayload
The type of the output event payload.
The CepEdgeStreamOperator<TInputPayload, TOutputPayload> type exposes the following members.

Properties

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. (Inherited from CepStreamOperator.) |
|
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. (Inherited from CepStreamOperator.) |

Remarks
The sync time for edge events is the StartTime for a start edge, the EndTime for an end edge, and the StartTime for a CTI.
