This method gets the value for each attribute in the list based upon its data reference configuration.

Namespace: OSIsoft.AF.Asset
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182

Syntax

public AFValues GetValue()

Public Function GetValue As AFValues

Dim instance As AFAttributes
Dim returnValue As AFValues

returnValue = instance.GetValue()

public:
AFValues^ GetValue()

member GetValue : unit -> AFValues

Return Value

Type: AFValues
Returns the value of each AFAttribute in this list. The index or order of each value in the returned collection corresponds to the index or order of the attributes in this list.

Remarks

This routine can be a more efficient mechanism to retrieve values from many attributes than calling one of the AFAttribute.GetValue Overload methods individually. This method achieves efficiency by reducing the number of round-trips to the associated server to read the data. The data will always be returned in the DefaultUOM of the respective attribute. Each returned AFValue will have its Attribute property set to the AFAttribute associated with the value.
