PIServer.ReplaceValues Method (AFTimeRange, IList(AFValues))

public AFErrors<AFValue> ReplaceValues(
	AFTimeRange timeRange,
	IList<AFValues> values
)

Public Function ReplaceValues ( 
	timeRange As AFTimeRange,
	values As IList(Of AFValues)
) As AFErrors(Of AFValue)

Dim instance As PIServer
Dim timeRange As AFTimeRange
Dim values As IList(Of AFValues)
Dim returnValue As AFErrors(Of AFValue)

returnValue = instance.ReplaceValues(timeRange, 
	values)

public:
AFErrors<AFValue^>^ ReplaceValues(
	AFTimeRange timeRange, 
	IList<AFValues^>^ values
)

member ReplaceValues : 
        timeRange : AFTimeRange * 
        values : IList<AFValues> -> AFErrors<AFValue> 

Parameters

timeRange

Type: OSIsoft.AF.TimeAFTimeRange
The bounding time range for replacement of the existing values.

values

Type: System.Collections.GenericIListAFValues
The list of replacement values with an associated PIPoint for each AFValues. If an empty AFValues then existing data within the specified AFTimeRange will be deleted. The timestamp of AFValue in values must be within the specified AFTimeRange.

Return Value

This method requires PI Data Archive 2016 or later that supports DeleteRange feature. This is indicated by Supports(PIServerFeature) check returning for the case of DeleteRange.

For successful data write through Buffer, this method requires that PI Buffer Subsystem (PIBufSS) needs to be correctly pre-configured with Buffering Manager. Currently, buffering data through PIBufSS has a limitation where error feedback from PI Data Archive cannot be returned to the caller.

Data write through Buffer will be fanned to Collective members.

Important
Exception reporting is not handled automatically by the AF SDK. Historically, exception reporting has been handled by the application writing data (i.e. Uniint-based interfaces).
