Detailed Description

Abstract base class for all state elements.

This is the abstract base class for all state elements. This class defines the following features for all of its derived classes:

Type identifiers: Each class of element has a unique (static) SoType identifier. The correct type id is also stored in each instance for easy access.

Copying: Elements are copied into the list of elements used in an SoCache. Performing any operation other than matches() on a copied element is not guaranteed to work (and will not work for things like Coordinates, if the coordinate they were pointing to has been deleted).

Stack indices: Since a subclass of an element class needs to be in the same state stack as the class from which it is derived, stack indices are inherited.

Capturing: Each time an element's value is accessed, that element is added to the elements-used list of all currently open caches.
