tar_cas_e(cas, key)
cas |
File path to the CAS repository. |
key |
Key of the object in the CAS system. |
The short function name helps reduce the size of the
tar_repository_cas()
format string and save space in the metadata.
tar_cas_e()
uses an in-memory cache
in a package internal environment to maintain a list of keys that
exists. This avoids expensive one-time lookups to the file system
during tar_make()
.
TRUE
if the key exists in the CAS system, FALSE
otherwise.
