Construct a new data pipe event given a pipe action and an AFvalue.

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

Syntax

public AFDataPipeEventWithChangeTime(
	AFDataPipeAction action,
	AFValue value,
	AFTime changeTime
)

Public Sub New ( 
	action As AFDataPipeAction,
	value As AFValue,
	changeTime As AFTime
)

Dim action As AFDataPipeAction
Dim value As AFValue
Dim changeTime As AFTime

Dim instance As New AFDataPipeEventWithChangeTime(action, 
	value, changeTime)

public:
AFDataPipeEventWithChangeTime(
	AFDataPipeAction action, 
	AFValue^ value, 
	AFTime changeTime
)

new : 
        action : AFDataPipeAction * 
        value : AFValue * 
        changeTime : AFTime -> AFDataPipeEventWithChangeTime

Parameters

action: Type: OSIsoft.AF.DataAFDataPipeAction
AFDataPipeAction of the event
value: Type: OSIsoft.AF.AssetAFValue
AFValue portion of the event. The Attribute/PIPoint property of the AFValue is used to identify the source of the AFDataPipeEvent.
changeTime: Type: OSIsoft.AF.TimeAFTime
The time the update occurred.

Remarks

AFDataPipeEvent will take ownership of the passed AFValue. If an application wants to assign the same value to multiple AFDataPipeEvents for different source AFAttributes, it should make copy of the AFValue and set the Attribute property of the AFValue before calling the constructor
