All Known Implementing Classes:

ItemInfoCacheImpl
```
public interface ItemInfoCache
```
ItemInfoCache instances are responsible for caching ItemInfos along with an opaque generation counter. Implementations are free on the particular caching policy. That is, how long (if at all) item infos are cached. An ItemInfoCache is supplied per session from the RepositoryService. It is used to cache ItemInfos read from the RepositoryService.
