AFEventFrame.AreValuesCaptured Property
This property indicates whether the AFEventFrame has captured its AFAttribute values.

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

Syntax

public bool AreValuesCaptured { get; }
Public ReadOnly Property AreValuesCaptured As Boolean
	Get

Dim instance As AFEventFrame
Dim value As Boolean

value = instance.AreValuesCaptured
public:
property bool AreValuesCaptured {
	bool get ();
}
member AreValuesCaptured : bool with get

Property Value

Type: Boolean
Indicates whether the AFEventFrame has captured its AFAttribute values so they are cached and any AFDataReference is not evaluated when reading their values.

Remarks

An AFEventFrame will capture its AFAttribute values when the AFEventFrameCaptureValues method is called. This method will evaluate the attribute values for the event frame and cache them so that the AFDataReference will not be used to read their values in the future. The AFEventFrameCaptureValues method can be called again to force the attribute values to be evaluated again and update their cached values.

The cached values are also evaluated again if the StartTime or EndTime are modified and the values are currently captured. Setting the EndTime to MaxValue will clear the captured values.
