Additional Inherited Members
Static Public Member Functions inherited from OpenSim::Object

static void	renameType (const std::string &oldTypeName, const std::string &newTypeName)
	Support versioning by associating the current %Object type with an old name.

	Return a pointer to the default instance of the registered (concrete) Object whose class name is given, or NULL if the type is not registered.
template<class T >
static bool	isObjectTypeDerivedFrom (const std::string &concreteClassName)
	Return true if the given concrete object type represents a subclass of the template object type T, and thus could be referenced with a T*.

	Create a new instance of the concrete %Object type whose class name is given as concreteClassName.
static void	getRegisteredTypenames (Array< std::string > &typeNames)

template<class T >
static void	getRegisteredObjectsOfGivenType (ArrayPtrs< T > &rArray)

static void	PrintPropertyInfo (std::ostream &os, const std::string &className, const std::string &propertyName)

static Object *	makeObjectFromFile (const std::string &fileName)
	Create an %OpenSim object whose type is based on the tag at the root node of the XML file passed in.

static bool	getSerializeAllDefaults ()
	Report the value of the "serialize all defaults" flag.
static bool	isKindOf (const char *type)
	Returns true if the passed-in string is "Object"; each %Object-derived class defines a method of this name for its own class name.

	Get current setting of debug level.
static Object *	SafeCopy (const Object *aObject)
