default

`default`#

Reducer definition for achieving columnsflow’s default reduction behavior in three steps:

remove unwanted events (using “event” mask of selection results)
create new collections (using “objects” mapping of selection results)
only keep certain columns after the reduction

Classes:

`cf_default_keep_columns`(args, *kwargs)
`cf_default`(args, *kwargs)

class cf_default_keep_columns(*args, **kwargs)[source]#

Bases: Reducer

Attributes:

`cache_instances`
`data_only`
`mc_only`
`require_calibrators`

Methods:

`call_func`(events, selection, **kwargs)	Reducer that does nothing but to define the columns to keep after the reduction in a backwards-compatible way using the "keep_columns" auxiliary config field as was the default in previous columnflow versions.
`post_init_func`(task, **kwargs)	Default post-init function.
`skip_func`(**kwargs)	Default skip function.
`update_cls_dict`(cls_name, cls_dict, get_attr)
