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>);

Recursively mounts all nested catalogs required to serve a path. If leaf_catalog is NULL, just indicate if it is necessary to load a nested catalog for the given path. The final leaf nested catalog is returned. The is_listable parameter is relevant if path is a nested catalog. Only if is_listable is true, the nested catalog will be used; otherwise the parent with the transaction point is sufficient.
