Detailed Description

template<class CatalogT>
class catalog::AbstractCatalogManager< CatalogT >

This class provides the read-only interface to a tree of catalogs representing a (subtree of a) repository. Mostly lookup functions filling DirectoryEntry objects. Reloading of expired catalogs, attaching of nested catalogs and delegating of lookups to the appropriate catalog is done transparently.

The loading / creating of catalogs is up to derived classes.

CatalogT is either Catalog or MockCatalog.

Usage: DerivedCatalogManager *catalog_manager = new DerivedCatalogManager(); catalog_manager->Init(); catalog_manager->Lookup(<inode>, &<result_entry>);

Opportunistic optimization: the client catalog manager uses this method to preload into the cache a nested catalog that is likely to be required next. Likely, because there is a race with the root catalog reload which may result in the wrong catalog being staged. That's not a fault though, the correct catalog will still be loaded with the write lock held. Note that this method is never used for root catalogs.
