* The SimpleCatalogManager is a simplistic concrete implementation of the |
5 |
|
|
* AbstractCatalogManager and allows for easy-to-use access to the catalog |
6 |
|
|
* structure of a given repository. This class is tailored for simplicity, not |
7 |
|
|
* for performance. Have a look into ClientCatalogManager if you are working |
8 |
|
|
* on the CVMFS client. |
