CepStream.SelectMany<TInput, TBind, TResult> Method (CepStream<TInput>, Expression<Func<CepStream<TInput>, CepStream<TBind>>>, Expression<Func<TInput, 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, TBind, TResult>(
    this CepStream<TInput> source,
    Expression<Func<CepStream<TInput>, CepStream<TBind>>> bind,
    Expression<Func<TInput, TBind, TResult>> selector
)

public:
generic<typename TInput, typename TBind, typename TResult>
[ExtensionAttribute]

    CepStream<TInput>^ source,
    Expression<Func<CepStream<TInput>^, CepStream<TBind>^>^>^ bind,

)

static member SelectMany<'TInput, 'TBind, 'TResult> : 
        source:CepStream<'TInput> *

<ExtensionAttribute>
Public Shared Function SelectMany(Of TInput, TBind, TResult) (
    source As CepStream(Of TInput),
    bind As Expression(Of Func(Of CepStream(Of TInput), CepStream(Of TBind))),
    selector As Expression(Of Func(Of TInput, TBind, TResult))
) As CepStream(Of TResult)

Parameters

• source
  Type: Microsoft.ComplexEventProcessing.Linq.CepStream<TInput>

  The outer input stream.

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

  The inner input stream.

• selector
  Type: System.Linq.Expressions.Expression<Func<TInput, TBind, TResult>>

  The mapping expression that defines a projection on the output.

Return Value

Type: Microsoft.ComplexEventProcessing.Linq.CepStream<TResult>

A stream where the result is a cross join of the outer and inner stream.

Type Parameters

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

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

• TResult
  The payload type of result events.

Remarks

Note that even in a cross join events from the inner and outer stream are only matched and output as a result of the join if their lifetimes overlap.
