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

Public Function ReplaceValues ( 
	timeRange As AFTimeRange,

	bufferOption As AFBufferOption
) As AFErrors(Of AFValue)

Dim instance As PIPoint
Dim timeRange As AFTimeRange

	values, bufferOption)

public:

	AFTimeRange timeRange, 
	IList<AFValue^>^ values, 
	AFBufferOption bufferOption
)

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

Parameters

timeRange

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

values

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

bufferOption

Type: OSIsoft.AF.DataAFBufferOption
An enumeration value that specifies buffering option.

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).
