CepStream.SelectMany<TInput, TGroupingKey, TBind, TResult> Method (CepGroupingStreams<TInput, TGroupingKey>, Expression<Func<CepStream<TInput>, CepWindowStream<TBind>>>, Expression<Func<IKey<TGroupingKey>, TBind, TResult>>)
Produces a stream based on the cross join of two input streams.
Namespace: Microsoft.ComplexEventProcessing.Linq
Assembly: Microsoft.ComplexEventProcessing (in Microsoft.ComplexEventProcessing.dll)
Syntax
public static CepStream<TResult> SelectMany<TInput, TGroupingKey, TBind, TResult>(
this CepGroupingStreams<TInput, TGroupingKey> source,
Expression<Func<CepStream<TInput>, CepWindowStream<TBind>>> bind,
Expression<Func<IKey<TGroupingKey>, TBind, TResult>> selector
)
Type Parameters
- TInput
The payload type of events from the outer input stream.
- TGroupingKey
The payload type of the grouping key.
- TBind
The payload type of events from the inner input stream.
- TResult
The payload type of result events.
Parameters
- source
Type: Microsoft.ComplexEventProcessing.Linq.CepGroupingStreams<TInput, TGroupingKey>
The grouping stream source.
- bind
Type: System.Linq.Expressions.Expression<Func<CepStream<TInput>, CepWindowStream<TBind>>>
The binding from grouping stream to window streaming.
- selector
Type: System.Linq.Expressions.Expression<Func<IKey<TGroupingKey>, TBind, TResult>>
The mapping expression that defines a projection on the output.
Return Value
Type: Microsoft.ComplexEventProcessing.Linq.CepStream<TResult>
A stream that is the result of SelectMany() and the window operation.
