Parameters

• source
  Type: Microsoft.ComplexEventProcessing.Linq.CepOrderableStream<TPayload>

  The stream source to order against.

• rankSelector
  Type: System.Linq.Expressions.Expression<Func<TPayload, TOrderKey>>

  The ranking expression whose value is used to compare events against each other.

Return Value

Type: Microsoft.ComplexEventProcessing.Linq.CepOrderedStream<TPayload>

An ordered stream that can furthur be ranked, for example, by using Take().

Type Parameters

• TPayload
  The payload type of input events.

• TOrderKey
