Inheritance diagram for SoUpgrader:

List of all members.

Public Member Functions
virtual SbBool	upgrade (SoInput *in, const SbName &refName, SoBase *&result)
	This is the key method that reads in fields, calls the createNewNode() method (which is responsible for looking at the fields read and setting the appropriate fields in the new node), and then reads in and adds children to the new node if it is derived from SoGroup.
Static Public Member Functions
static SoUpgrader *	getUpgrader (const SbName &className, float fileFormatVersion)
	Find out if an upgrader exists for a specific class and a specific version of the file format.
static void	initClass ()
	Initializes base node class.
static void	initClasses ()
	Initialize ALL upgraders.
Protected Member Functions
virtual SoNode *	createNewNode ()=0
	Subclasses MUST define this...
	SoUpgrader ()
	Constructor.
virtual	~SoUpgrader ()
Static Protected Member Functions
static void	registerUpgrader (const SoType &type, const SbName &className, float version)
	Register a converter for a specific class and a specific file format.
Protected Attributes
SbBool	isGroup
	This is set to TRUE in the SoUpgrader constructor.

Member Data Documentation

SbBool SoUpgrader::isGroup [protected]

A subclass should set this to FALSE in its constructor if its createNewNode() method returns a group node but the node being upgraded is not really a group; it keeps children from being read.
