Remarks

The OpcLabs.BaseLib.OperationModel.OperationResult.State object is valid independent of whether the operation has succeeded or failed. It is a copy of the OpcLabs.BaseLib.OperationModel.OperationArguments.State object passed to the operation as its input. The semantics of this value depends on the application.

The getter method of this property is pure, i.e. it does not have observable side effects.
