Detailed Description

Base class for handling input/output of groups.

library ilvproto

Group files should not be created directly by the application: they are created internally by the load() and save() methods of the group, or by the prototype-specific subclasses ofIlvManagerwhen savingilv` files. You will never need to use this class directly, unless you write new subclasses of IlvGroupNode.
