Namespace: OSIsoft.AF.Asset
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182
Syntax
public AFValues GetValues( AFAnalysis analysis, IList<AFCase> cases, UOM desiredUOM )
Public Function GetValues ( analysis As AFAnalysis, cases As IList(Of AFCase), desiredUOM As UOM ) As AFValues Dim instance As AFAttribute Dim analysis As AFAnalysis Dim cases As IList(Of AFCase) Dim desiredUOM As UOM Dim returnValue As AFValues returnValue = instance.GetValues(analysis, cases, desiredUOM)
public: AFValues^ GetValues( AFAnalysis^ analysis, IList<AFCase^>^ cases, UOM^ desiredUOM )
member GetValues : analysis : AFAnalysis * cases : IList<AFCase> * desiredUOM : UOM -> AFValues
Parameters
- analysis
- Type: OSIsoft.AF.AnalysisAFAnalysis
If all the cases in the cases list are from the same AFAnalysis, then specify the owning analysis in this parameter so the case results can be obtained more efficiently from the server. If this parameter is , then the result is obtained from each specified AFCase in the list one at a time. - cases
- Type: System.Collections.GenericIListAFCase
The list of AFCase objects from which get the attribute's value. - desiredUOM
- Type: OSIsoft.AF.UnitsOfMeasureUOM
The desired unit of measure for the returned values. If not specified or , then the values are returned in the unit of measure specified by the DefaultUOM property.
Return Value
Type: AFValuesReturns the collection of values for the attribute sorted in increasing time order.
Remarks
The returned collection of AFValue objects represent the values of
the attribute in each of the cases in the specified UOM. See
GetValue Overload for more specific information
on UOM and type conversion. This is equivalent to retrieving the collection of
attribute values that would have been returned by calling
GetValue(AFCase, UOM) with the context of each case
in the collection.
