Syntax

[DataContractAttribute]
public abstract class CepStreamOperator<TInputEvent, TInputPayload, TOutputPayload> : CepStreamOperator
where TInputEvent : TypedEvent<TInputPayload>

Type Parameters

TInputEvent
The type of the input event.

TInputPayload
The type of the input payload.

TOutputPayload
The type of the output payload.

The CepStreamOperator<TInputEvent, TInputPayload, TOutputPayload> type exposes the following members.

Properties

	Name	Description
	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.)
