Retrieves refnum information from a variant that contains a refnum data type.
This node returns an error if the variant does not contain a refnum.
Variant data from which you want to retrieve data type information.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Type of the object that is associated with the refnum stored in the variant. For example, if the variant contains a refnum that points to a VI, this output returns a reference type of LVObjVI.
Strict type of the refnum stored in the variant, if the refnum is strictly typed. Otherwise, this output returns an empty string.
VI server class name of the object that is associated with the refnum stored in the variant. This output is valid only if reference type is LVObjUnknown.
