The Class Method Node acts like an Invoke Node but it accepts Classes and DVRs (By-Reference Classes) instead of VI Server references.

* Knows the context of the VI it is being used in
- Will show Private methods if VI is owned by the wired class
- Will show Protected methods if VI is owned by the wired class or child of the wired class
- Will show Community methods if VI is owned by a class that is a friend of the wired class
- Will show Public methods under any condition
* Wiring selects Class
* Left-click selects Method

So why use it?
1. Makes Class Methods easier to find and use.
2. In the case of By-Reference Classes, takes care of In Place Element Structure DVR reads and writes.

Known Issue and Workaround
Won't automatically update if the connector pane of the Method changes. If a Method is changed and LabVIEW can coerce the data type, then the method will not cause a broken run arrow.

To force the node to update, select a different method and then select the desired method again.
