Abstract base class for all state elements.
Thetype exposes the following members.
Determines whether the specified(Inherited from is equal to the current . .)
Returns the stack id for the element type.
Overrides(Inherited from . SoNetBase.)
Gets the(Inherited from of the current instance. .)
Returns a string that represents the current object.(Inherited from .)
This is the abstract base class for all state elements. This class defines the following features for all of its derived classes:
<B> Type identifiers: </B> Each class of element has a unique (static) SoType identifier. The correct type id is also stored in each instance for easy access. <B> Copying: </B> 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). <B> Stack indices: </B> 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. <B> Capturing: </B> Each time an element's value is accessed, that element is added to the elements-used list of all currently open caches.
