The object placeholder is an object expression that evaluates to an IPIValueAttribute object.
This is a read-only property. The values it returns are populated when you retrieve a PIValue from a PI server (or create a new PIValue). The enum PIValueFlagBitMask can be used to extract specific bits.
|eAnnotatedMask||1||The value is annotated.|
|eQuestionableMask||2||The value is marked "questionable". This is set by applications.|
|eSubstitutedMask||4||The value has been substituted (edited) in the data archive. It is not the original value.|
