Article
04/29/2016

Converts a CepStream of point events with the specified event order to an event sink that implements the IObservable interface.

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

Syntax

public static ICepObservable<PointEvent<TPayload>> ToPointObservable<TPayload>(
    this CepStream<TPayload> stream,
    StreamEventOrder streamEventOrder
)

public:
generic<typename TPayload>
[ExtensionAttribute]
static ICepObservable<PointEvent<TPayload>^>^ ToPointObservable(
    CepStream<TPayload>^ stream,
    StreamEventOrder streamEventOrder
)

static member ToPointObservable<'TPayload> : 
        stream:CepStream<'TPayload> *
        streamEventOrder:StreamEventOrder -> ICepObservable<PointEvent<'TPayload>>

<ExtensionAttribute>
Public Shared Function ToPointObservable(Of TPayload) (
    stream As CepStream(Of TPayload),
    streamEventOrder As StreamEventOrder
) As ICepObservable(Of PointEvent(Of TPayload))

Parameters

stream
Type: Microsoft.ComplexEventProcessing.Linq.CepStream<TPayload>

The fully bound event source from which the observable event sink is created.

streamEventOrder
Type: Microsoft.ComplexEventProcessing.StreamEventOrder

One of the enumeration values that specifies how events are ordered.

Return Value

Type: Microsoft.ComplexEventProcessing.Linq.ICepObservable<PointEvent<TPayload>>

An event sink that supports observation.

Type Parameters

TPayload
Type of the event payload.

Remarks

Calling the Subscribe method of the observable event sink initializes and starts a query. The query is deleted when the subscription is disposed.

The ICepObservable<T> interface includes an overload of Subscribe that lets you specify a name and description for the query. These additional properties are useful for debugging.

For more information about the data types that are supported in the payload of an event, see Event Structure.
