Owning Palette: Cluster, Class, & Variant VIs and Functions

Requires: Base Development System

Calls the nearest ancestor implementation of a class method. You can use the Call Parent Method node only on the block diagram of a member VI that belongs to a class that inherits member VIs from an ancestor class. The child member VI must be a dynamic dispatching member VI and have the same name as the ancestor member VI.

The parameters, or input and output terminals, of this node depend on the ancestor member VI and change to match the ancestor member VI exactly. This node adopts the VI icon of the ancestor member VI with a glyph in the bottom, left corner of the subVI to indicate the subVI is calling the ancestor member VI instead of dynamically dispatching as a dynamic subVI node does typically.
