    Expression<Func<IKey<TGroupingKey>, TBind, TResult>> selector
)

Type Parameters

  • TInput
    The payload type of events from the outer input stream.
  • TGroupingKey

  • TBind
    The payload type of events from the inner input stream.
  • TResult
    The payload type of result events.

Parameters

Return Value

Type: Microsoft.ComplexEventProcessing.Linq.CepStream<TResult>
A stream that is the result of SelectMany() and the window operation.
