Check if the method of the class is the same as in its parent class, or if it has
been overridden.
Useful for determining if *e.g.* `validation_histograms` has been defined for a
particular skim.

◆ additional_setup()
| def additional_setup |
( |

Perform any setup steps necessary before running the skim. This may include:
* applying event-level cuts using `ifEventPasses`,
* adding the `MCMatcherParticles` module to the path,
* running the FEI.
Warning:
Standard particle lists should *not* be loaded in here. This should be done
by overriding the method `BaseSkim.load_standard_lists`. This is crucial for
avoiding loading lists twice when combining skims for production.
Parameters:
path (basf2.Path): Skim path to be processed.
Reimplemented from BaseSkim.

Apply the ``hlt_hadron`` selection if the property ``ApplyHLTHadronCut`` is True.
Parameters:
path (basf2.Path): Skim path to be processed.

◆ build_lists()
| def build_lists |
( |

Create the skim lists to be saved in the output uDST. This function is where
the main skim cuts should be applied. At the end of this method, the attribute
``SkimLists`` must be set so it can be used by `output_udst`.
Parameters:
path (basf2.Path): Skim path to be processed.
Reimplemented from BaseSkim.
Definition at line 604 of file systematics.py.
◆ code()
◆ flag()
Event-level variable indicating whether an event passes the skim or not. To use
the skim flag without writing uDST output, use the argument ``udstOutput=False``
when instantiating the skim class.

◆ get_skim_list_names()
| def get_skim_list_names |

◆ initialise_skim_flag()
| def initialise_skim_flag |
( |
|
self, |
|

| |

Add the module `skimExpertFunctions.InitialiseSkimFlag` to the path, which
initialises flag for this skim to zero.

◆ load_standard_lists()
| def load_standard_lists |
( |
|
self, |
|
|
|
path |
|
) |
| |
Load any standard lists. This code will be run before any
`BaseSkim.additional_setup` and `BaseSkim.build_lists`.
Note:
This is separated into its own function so that when skims are combined, any
standard lists used by two skims can be loaded just once.
Parameters:
path (basf2.Path): Skim path to be processed.
Reimplemented from BaseSkim.

◆ output_udst()

Write the skim particle lists to an output uDST and print a summary of the
skim list statistics.
Parameters:
path (basf2.Path): Skim path to be processed.
Reimplemented in CombinedSkim.

◆ postskim_path()
| def postskim_path |

Return the skim path.
* If `BaseSkim.skim_event_cuts` has been run, then the skim lists will only be
created on a conditional path, so subsequent modules should be added to the
conditional path.
* If `BaseSkim.skim_event_cuts` has not been run, then the main analysis path is
returned.

◆ set_skim_logging()

Turns the log level to ERROR for selected modules to decrease the total size
of the skim log files. Additional modules can be silenced by setting the attribute
`NoisyModules` for an individual skim.
Parameters:
path (basf2.Path): Skim path to be processed.
.. warning::
This method works by inspecting the modules added to the path, and setting
the log level to ERROR. This method should be called *after* all
skim-related modules are added to the path.
Reimplemented in CombinedSkim.
Definition at line 834 of file skimExpertFunctions.py.
◆ skim_event_cuts()

( |
|
self, |
|
|
|
cut, |

|
* |
path |
|
) |
| |
|
inherited |
Apply event-level cuts in a skim-safe way.
Parameters:
cut (str): Event-level cut to be applied.
path (basf2.Path): Skim path to be processed.
Returns:
ConditionalPath (basf2.Path): Path on which the rest of this skim should be
processed. On this path, only events which passed the event-level cut
will be processed further.
.. Tip::
If running this function in `BaseSkim.additional_setup` or
`BaseSkim.build_lists`, redefine the ``path`` to the path returned by
`BaseSkim.skim_event_cuts`, *e.g.*
.. code-block:: python
def build_lists(self, path):
path = self.skim_event_cuts("nTracks>4", path=path)
# rest of skim list building...
.. Note::
The motivation for using this function over `applyEventCuts` is that
`applyEventCuts` completely removes events from processing. If we combine
multiple skims in a single steering file (which is done in production), and
the first has a set of event-level cuts, then all the remaining skims will
never even see those events.
Internally, this function creates a new path, which is only processed for
events passing the event-level cut. To avoid issues around particles not
being available on the main path (leading to noisy error logs), we need to
add the rest of the skim to this path. So this new path is assigned to the
attribute ``BaseSkim._ConditionalPath``, and ``BaseSkim.__call__`` will run
all remaining methods on this path.

◆ update_skim_flag()
| def update_skim_flag |
( |

self, |

path |

| |
|
inherited |
Add the module `skimExpertFunctions.InitialiseSkimFlag` to the path, which
initialises flag for this skim to zero.
.. Warning::
If a conditional path has been created before this, then this function
*must* run on the conditional path, since the skim lists are not guaranteed
to exist for all events on the main path.
