The SBCClass library defines fundamental mechanisms used for class introspection. In particular, all exposed classes in SAMSON derive from SBCClass, and each exposed class has an associated class proxy, derived from SBCClassProxy, that contains a description of the class factory (its constructors) and the class interface (its functions):

SBCClass (short name SBClass)
SBCClassConstructor (short name SBConstructor)
SBCClassFactory (short name SBFactory)
SBCClassFunction (short name SBFunction)
SBCClassInterface (short name SBInterface)
SBCClassProxy (short name SBProxy)
