Namespace:   Microsoft.ComplexEventProcessing.Linq
Assembly:  Microsoft.ComplexEventProcessing (in Microsoft.ComplexEventProcessing.dll)

Syntax

public static CepStream<TResult> Select<TInput, TResult>(
    this CepWindowStream<CepWindow<TInput>> source,
    Expression<Func<CepWindow<TInput>, TResult>> selector
)

public:
generic<typename TInput, typename TResult>
[ExtensionAttribute]
static CepStream<TResult>^ Select(
    CepWindowStream<CepWindow<TInput>^>^ source,
    Expression<Func<CepWindow<TInput>^, TResult>^>^ selector
)

static member Select<'TInput, 'TResult> : 
        source:CepWindowStream<CepWindow<'TInput>> *
        selector:Expression<Func<CepWindow<'TInput>, 'TResult>> -> CepStream<'TResult>

<ExtensionAttribute>
Public Shared Function Select(Of TInput, TResult) (
    source As CepWindowStream(Of CepWindow(Of TInput)),
    selector As Expression(Of Func(Of CepWindow(Of TInput), TResult))
) As CepStream(Of TResult)

Parameters

• source
  Type: Microsoft.ComplexEventProcessing.Linq.CepWindowStream<CepWindow<TInput>>

  The stream of windows.

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

  Defines the mapping expression.

Return Value

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

A stream which is the union of all window streams.

Type Parameters

• TInput
  The input event payload type of the window.

• TResult
