The RootSchema does not have subclasses of Array for all of the primitive types; for example, Any, MemoryAddress, and TimeStampOffset. If you require such an array, subclass the Array class in your user schema, selecting the required type as the membership.

For Array classes that are internal pseudo arrays (that is, arrays of GUI‑related information only in the Jade run time module), the only Array class methods that are implemented are at, atPut, and createIterator. The atPut method is implemented only for primitive type elements on a ListBox, ComboBox, or Table control; that is, it is not implemented for a collection of controls and menu items.
