Detailed Description

The struct OksAliasTable is used to support aliases.

The technique of aliases is used to reduce size of OKS data files: if a class name appears first time somewhere in OKS data file it is marked in front by '@' symbol and the alias to it is used later, e.g.:

• first object stored in data file is "Detector@First" and it will be stored as "@Detector@First"
• second object stored in data file is "Detector@Second" and it will be stored as "0@Second"
• in this case "0" is alias for "Detector"

The technique of aliases is used to keep compatibility with old data format: new method to read OKS data files may read new and old format at the same time
