Syntax

public class CepGroupingStreams<TPayload, TGroupingKey>

generic<typename TPayload, typename TGroupingKey>
public ref class CepGroupingStreams

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>>)	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. 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.
