SoSField
The SoSField class is the base class for fields which contains only a single value.All field types which should always contain only a single member value inherits this class. SoSField is an abstract class.
Definition: SoSField.h:29
SoSFEnum
The SoSFEnum class is a container for an enum value.This field is used where nodes, engines or other field containers needs to store one particular value out of an enumerated set.
