LabVIEW Object-Oriented Programming (LVOOP) was introduced in LabVIEW 8.20. LVOOP allows developers to build recursive tree-like data structures within LabVIEW dataflow model. Recursive data structures are enabled by allowing class private data members to be of ancestor class type. As ancestor class private data members can hold descendant class objects, recursive data structures are possible.

However LabVIEW doesn’t allow using recursive type structures where a type refers to itself. I present here that indeed building such types would be possible within the dataflow framework of LabVIEW. Such recursive types would allow building recursive data structures in more intuitive and type safe manner than what is possible with current LVOOP implementation.
