Detailed Description

template<class ObjectFetcherT>
struct swissknife::CatalogTraversalBase< ObjectFetcherT >::Parameters

Parameters
repo_urlthe path to the repository to be traversed: -> either absolute path to the local catalogs -> or an URL to a remote repository
repo_namefully qualified repository name (used for remote repository signature check) (optional)
repo_keysa comma separated list of public key file locations to verify the repository manifest file
historydepth of the desired catalog history traversal (default: 0 - only HEAD catalogs are traversed)
timestamptimestamp of history traversal threshold (default: 0 - no threshold, traverse everything)
no_repeat_historykeep track of visited catalogs and don't re-visit them in previous revisions
no_closedo not close catalogs after they were attached (catalogs retain their parent/child pointers)
ignore_load_failuresuppressed an error message if a catalog file could not be loaded (i.e. was sweeped before by a garbage collection run)
quietsilence messages that would go to stderr
tmp_dirpath to the temporary directory to be used (default: /tmp)

ONLY FOR CatalogTraversalParallel

Parameters
num_threadsnumber of threads concurrently traversing the catalog trees; hint: set up based on CPU utilization and optimal number of download threads (default: 8)
serialize_callbacksdo not call multiple catalog callbacks concurrently; ensures safe access to shared variables inside the callback; turn off if the registered callback is thread-safe (default: true)
