Constructor & Destructor Documentation

◆ AlgHist() [1/2]

MD::AlgHist::AlgHist ( )

effects: default constructor guarantee: no-fail rationale: this should only be called by serialization

◆ AlgHist() [2/2]

MD::AlgHist::AlgHist ( TH1 val_hist_swallow,
const std::string &  val_value0,
const std::string &  val_value1 = "",
const std::string &  val_value2 = "",
const std::string &  val_value3 = "" 
)

effects: constructor for the given histogram spec, value, and weight guarantee: strong failures: out of memory II failures: insufficient values passed requires: val_hist_swallow != 0

◆ ~AlgHist()

MD::AlgHist::~AlgHist ( )

effects: destructor guarantee: no-fail rationale: this is needed to delete the template histogram

Member Function Documentation

◆ book()

void EL::Algorithm::book ( const TH1 hist)
inherited

book the given histogram

Guarantee
strong
Failures
histogram booking error

◆ changeInput()

virtual StatusCode EL::Algorithm::changeInput ( bool  firstFile)
privatevirtualinherited

effects: do all changes to work with a new input file, e.g.

set new branch addresses. if firstFile is set, this method is called just before init() is called

Warning: If a file is split across multiple jobs this will be called more than once. This only happens for specific batch drivers and/or if it is explicitly configured by the user. With PROOF it could even happen multiple times within the same job, and while PROOF is no longer supported that behavior may come back if support for a similar framework is added in the future. As such, this method should not be used for accounting that relies to be called exactly once per file, take a look at fileExecute() if you want something that is guaranteed to be executed exactly once per input file.

Warning: The execution order of changeInput and fileExecute is currently unspecified.

guarantee: basic failures: algorithm dependent

Reimplemented in EL::DuplicateChecker, EL::UnitTestAlg1, EL::UnitTestAlg, EL::UnitTestAlgXAOD, EL::NTupleSvc, MD::FormulaSvc, and EL::UnitTestSkim.

◆ ClassDef()

MD::AlgHist::ClassDef ( AlgHist  ,
 
)
private

◆ endOfFile()

virtual StatusCode EL::Algorithm::endOfFile ( )
privatevirtualinherited

effects: do the post-processing for each input file guarantee: basic failures: algorithm dependent rationale: this is mainly used for specialized services that need to save partial results for each input file

Reimplemented in EL::MetricsSvc.

◆ evtStore()

asg::SgTEvent* EL::Algorithm::evtStore ( ) const
inherited

get the (main) event store for this algorithm

This is mostly to mirror the method of the same name in AthAlgorithm, allowing to make the tutorial instructions more dual-use.

Guarantee
strong
Failures
out of memory I
job not configured for xAODs

◆ execute()

virtual EL::StatusCode MD::AlgHist::execute ( )
privatevirtual

effects: process the next event guarantee: basic failures: algorithm dependent rationale: the virtual part of Algorithm::process

Reimplemented from EL::Algorithm.

◆ fileExecute()

virtual StatusCode EL::Algorithm::fileExecute ( )
privatevirtualinherited

effects: do all the processing that needs to be done once per file

Warning: The user should not expect this to be called at any particular point in execution. If a file is split between multiple jobs this will be called in only one of these jobs, and not the others. It usually gets called before the first event in a file, but that is not guaranteed and relying on this is a bug. Take a look at changeInput if you want something that is guaranteed to be executed at the beginning of each input file.

Warning: The execution order of changeInput and fileExecute is currently unspecified.

guarantee: basic failures: algorithm dependent rationale: this is to read per-file accounting data, e.g. the list of lumi-blocks processed

Reimplemented in EL::UnitTestAlg1, EL::UnitTestAlg, EL::UnitTestAlgXAOD, and EL::MetricsSvc.

◆ finalize()

virtual StatusCode EL::Algorithm::finalize ( )
privatevirtualinherited

effects: do everything that needs to be done after completing work on this worker guarantee: basic failures: algorithm dependent rationale: currently there is no use foreseen, but this routine is provided regardless

Reimplemented in EL::UnitTestAlg1, EL::UnitTestAlg, and EL::UnitTestAlgXAOD.

◆ hasName()

virtual bool EL::Algorithm::hasName ( const std::string &  name) const
privatevirtualinherited

returns: whether this algorithm has the given name guarantee: basic failures: algorithm dependent rationale: this is to allow an algorithm to be known by multiple names.

this is needed for NTupleSvc, so that it can be located with and without the output tree name.

Reimplemented in EL::NTupleSvc.

◆ hist()

TH1* EL::Algorithm::hist ( const std::string &  name) const
inherited

get the histogram with the given name

Guarantee
strong
Failures
histogram not found

◆ histFinalize()

virtual StatusCode EL::Algorithm::histFinalize ( )
privatevirtualinherited

effects: this is a post-initialization routine that is called after finalize has been called.

guarantee: basic failures: algorithm dependent rationale: unlike finalize(), this method is called all the time, even on empty input files.

Reimplemented in EL::UnitTestAlg1, EL::UnitTestAlg, EL::UnitTestAlgXAOD, and EL::MetricsSvc.

◆ histInitialize()

virtual StatusCode EL::Algorithm::histInitialize ( )
privatevirtualinherited

effects: this is a pre-initialization routine that is called before changeInput is called.

guarantee: basic failures: algorithm dependent rationale: unlike initialize(), this method is called all the time, even on empty input files. so you should create any histograms or n-tuples here that subsequent code expects

Reimplemented in EL::UnitTestAlg1, EL::UnitTestAlg, EL::UnitTestAlgXAOD, EL::MetricsSvc, and EL::VomsProxySvc.

◆ initialize()

virtual EL::StatusCode MD::AlgHist::initialize ( )
privatevirtual

effects: do everything that needs to be done before running the algorithm, e.g.

create output n-tuples and histograms. this method is called only once right after changeInput(true) is called guarantee: basic failures: algorithm dependent rationale: in principle all this work could be done on changeInput(true). However, providing this method should make it easier for the user to set up all his outputs and to do so only once.

Reimplemented from EL::Algorithm.

◆ msg() [1/2]

MsgStream& EL::Algorithm::msg ( ) const
inherited

messaging interface

this is the interface to work with the standard messaging macros from AsgTools. Instead of enums I pass ints, so that I can avoid the include dependency (forward declarations are only allowed for enum classes AFAIK).

◆ msg() [2/2]

MsgStream& EL::Algorithm::msg ( int  level) const

◆ postExecute()

virtual StatusCode EL::Algorithm::postExecute ( )
privatevirtualinherited

effects: do the post-processing for the event guarantee: basic failures: algorithm dependent rationale: this is mainly used for specialized services that need to get input from subsequent algorithms before filling their event data

Reimplemented in EL::NTupleSvc.

◆ setMsgLevel()

void EL::Algorithm::setMsgLevel ( int  level)
inherited

set the message level for the message stream for this object

Guarantee
no-fail

◆ setupJob()

virtual EL::StatusCode MD::AlgHist::setupJob ( EL::Job job)
privatevirtual

effects: give the algorithm a chance to intialize the job with anything this algorithm needs.

this method is automatically called before the algorithm is actually added to the job. guarantee: basic failures: algorithm dependent rationale: this is currently used to give algorithms a chance to register their output datasets, but can also be used for other stuff.

Reimplemented from EL::Algorithm.

◆ sysSetupJob()

void EL::Algorithm::sysSetupJob ( Job job)
privateinherited

effects: give the algorithm a chance to intialize the job with anything this algorithm needs.

this method is automatically called before the algorithm is actually added to the job. guarantee: basic failures: algorithm dependent rationale: this is currently used to give algorithms a chance to register their output datasets, but can also be used for other stuff.
