Parameters

• source
  Type: Microsoft.ComplexEventProcessing.Linq.CepGroupingStreams<TInput, TGroupingKey>

  The stream source.

• bind
  Type: System.Linq.Expressions.Expression<Func<CepStream<TInput>, CepStream<TBind>>>

  The bind information that bind the second stream to the first stream.

• 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 can be used for further apply logic in the Group and Apply.

Type Parameters

• TInput
  The payload type of input events.

• TGroupingKey
  The payload type of grouping key events.

• TBind
  The payload type of bound events.

• TResult
  The payload type of result events.
