Changed Methods

LabVIEW 2020 includes the following changed methods:

  • The Consider Parent Classes parameter of the LVClassLibrary:Has Implementation? method is renamed Consider Parents. This method returns an error if the class inherits multiple methods of the same name from parent interfaces and does not provide its own override.
