Methods Summary

available_table([modifiers, allow_protocols])	Get the path to the first available table.
update([parallelize, wdir, modifiers])	Update the different tables registered within this manager.

Methods Documentation

add_table(path, protocol=None)

Add a new table to the list of tables. The path is automatically transformed into the corresponding ProtocolPath instance.

Parameters:path (str) – path to the new table.

available_table(modifiers=None, allow_protocols=None)

Get the path to the first available table. The behavior is similar to that of hep_rfm.available_path.

Parameters:

• modifiers (dict) – modifiers to be applied in the set of paths.
• allow_protocols (container(str)) – possible protocols to consider.

Returns:

path to the first available table.

Return type:

str

available_path()

update(parallelize=False, wdir=None, modifiers=None)

Update the different tables registered within this manager.

Parameters:

• parallelize (int) – number of processes allowed to parallelize the synchronization of all the proxies. By default it is set to 0, so no parallelization is done.
• wdir (str) – where to create the temporary directory. The option is passed to tempfile.TemporaryDirectory as “dir”.
• modifiers (dict) – information to modify the path of this class. For more information on its structure, see the definition of hep_rfm.ProtocolPath.with_modifiers() for each protocol.

Raises:

RuntimeError – if a file is missing for any of the tables.
