Here is the caller graph for this function:

Catalog * catalog::SimpleCatalogManager::CreateCatalog ( const PathString mountpoint,
const shash::Any catalog_hash,
Catalog parent_catalog 
)
protectedvirtual

Create a new Catalog object. Every derived class has to implement this and return a newly created (derived) Catalog structure of it's desired type.

Parameters
mountpointthe future mountpoint of the catalog to create
catalog_hashthe content hash of the catalog database
parent_catalogthe parent of the catalog to create
Returns
a newly created (derived) Catalog

Implements catalog::AbstractCatalogManager< Catalog >.

Reimplemented in catalog::WritableCatalogManager.

Loads a catalog via HTTP from Statum 0 into a temporary file.

Parameters
url_paththe url of the catalog to load
mount_pointthe file system path where the catalog should be mounted
catalog_filea pointer to the string containing the full qualified name of the catalog afterwards
Returns
0 on success, different otherwise
