Syntax
public virtual AFValues InterpolatedValuesAtTimes( IList<AFTime> times, string filterExpression, bool includeFilteredValues, AFAttributeList inputAttributes, AFValues[] inputValues )
Public Overridable Function InterpolatedValuesAtTimes ( times As IList(Of AFTime), filterExpression As String, includeFilteredValues As Boolean, inputAttributes As AFAttributeList, inputValues As AFValues() ) As AFValues Dim instance As AFDataReference Dim times As IList(Of AFTime) Dim filterExpression As String Dim includeFilteredValues As Boolean Dim inputAttributes As AFAttributeList Dim inputValues As AFValues() Dim returnValue As AFValues returnValue = instance.InterpolatedValuesAtTimes(times, filterExpression, includeFilteredValues, inputAttributes, inputValues)
public: virtual AFValues^ InterpolatedValuesAtTimes( IList<AFTime>^ times, String^ filterExpression, bool includeFilteredValues, AFAttributeList^ inputAttributes, array<AFValues^>^ inputValues )
abstract InterpolatedValuesAtTimes : times : IList<AFTime> * filterExpression : string * includeFilteredValues : bool * inputAttributes : AFAttributeList * inputValues : AFValues[] -> AFValues override InterpolatedValuesAtTimes : times : IList<AFTime> * filterExpression : string * includeFilteredValues : bool * inputAttributes : AFAttributeList * inputValues : AFValues[] -> AFValues
Parameters
- times
- Type: System.Collections.GenericIListAFTime
List of timestamps at which to retrieve interpolated values - filterExpression
- Type: SystemString
A string containing a filter expression. Expression variables are relative to the attribute. Use '.' to reference the containing attribute. A or empty string indicates no filtering. If the attribute does not support the Filters option, the filter will be ignored. - includeFilteredValues
- Type: SystemBoolean
Specify to indicate that values which fail the filter criteria are present in the returned data at the times where they occurred with a value set to a "Filtered" enumeration value with bad status. Repeated consecutive failures are omitted. - 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.
Return Value
Type: AFValuesReturns an AFValues collection with the interpolated values at the specified times.
Exceptions
| Exception | Condition |
|---|---|
| NotSupportedException | The data reference does not support the this method, or the configured data reference does not support filter expressions and one was provided. |
| ArgumentNullException | The times is . |
| ArgumentException | The times list must be monotonic. |
Remarks
| This method, property, or class is not available in the legacy .NET 3.5 version of the SDK. |
