Namespace: Microsoft.ComplexEventProcessing.Linq
Assembly: Microsoft.ComplexEventProcessing (in Microsoft.ComplexEventProcessing.dll)
Syntax
public class CepGroupingStreams<TPayload, TGroupingKey>
Type Parameters
- TPayload
The type of the event payload.
- TGroupingKey
The type of the grouping key.
The CepGroupingStreams<TPayload, TGroupingKey> type exposes the following members.
Methods
| Name | Description | |
|---|---|---|

ApplyWithUnion<TApplyOutput>(Expression<Func<CepStream<TPayload>, CepStream<TApplyOutput>>>) | Applies the query logic specified by the applybranch parameter to a grouped stream. Produces a result stream per group and unions all result streams together. |
|
ApplyWithUnion<TUnionOutput, TApplyOutput>(Expression<Func<CepStream<TPayload>, CepStream<TApplyOutput>>>, Expression<Func<KeyedPayload<TGroupingKey, TApplyOutput>, TUnionOutput>>) | Supplies the query logic specified by the applybranch parameter to a grouped stream. Produces a result stream per group and unions all result streams together. The selector parameter is a lambda expression that allows additional project operations on the output and provides access to grouping fields. |

Remarks
CepGroupingStreams restricts the programming surface area once a grouping construct has been specified. The set of methods exposed to the programmer cover multiple types. Each of these types surfaces only the set of operators available to the programmer. The transition between any of these types is carefully controlled by the operations so that problems surface early at compile time rather than at runtime.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
