Parameters

times
Type: System.Collections.GenericIListAFTime
List of time stamps at which to retrieve recorded values.
mode
Type: OSIsoft.AF.DataAFRetrievalMode
The mode is used to determine the value to return when a value does not exist at the exact time specified. The value is taken from the AFRetrievalMode enumeration.
inputAttributes
Type: OSIsoft.AF.AssetAFAttributeList
The input attributes as previously specified by the data reference in the GetInputs(Object) call. The index of the values will match the index of the corresponding attribute previously returned. These values must be converted to the appropriate UOM required by this data reference.
inputValues
Type: OSIsoft.AF.AssetAFValues
The input values are supplied to the data reference based on the attributes returned in the GetInputs(Object) call. The index of the values will match the index of the corresponding attribute previously returned. These values must be converted to the appropriate UOM required by this data reference.
cancellationToken
Type: System.ThreadingCancellationToken
A cancellation token used to abort processing before completion. Passing the default CancellationToken.None will run to completion or until the PIConnectionInfo.OperationTimeOut period elapses.

Return Value

Type: TaskAFValues
Returns a task whose result is an AFValues collection with the recorded values at the specified times.

Exceptions

ExceptionCondition
AggregateException Asynchronous methods throw AggregateException on failure which will contain one or more exceptions containing the failure.
ArgumentNullException The times is .
ArgumentException The times list must be monotonic.

Remarks

Note Notes to Callers
This method, property, or class is not available in the legacy .NET 3.5 version of the SDK.

Note Notes to Callers
