Detailed Description

Main class for reading groups from a stream. It provides contextual information.

Library: ilvproto

Group files should not be created directly by the application: they are generated internally by methods of other classes of the prototypes library. You will never need to use this class directly, unless you write new subclasses of IlvGroupNode.
