Detailed Description

Steering task for the EMCal correction framework.

This class is the steering class for the cell and cluster level corrections for the EMCal. A YAML configuration file is utilized to determine which corrections should be run and how they should be configured. The corrections are initialized by calling their Initialize() function. Similar to AliAnalysisTaskEmcal, the relevant event information is loaded, and then the Run() function of each correction is called.

In general, this steering class handles all of the configuration of the corrections, including passing the relevant EMCal containers and event objects.

Note: YAML does not play nicely with CINT and dictionary generation, so it is hidden using conditional inclusion.

Member Function Documentation

AliClusterContainer* AliEmcalCorrectionTask::AddClusterContainer ( const char * n )

inline

Definition at line 119 of file AliEmcalCorrectionTask.h.

AliEmcalContainer * AliEmcalCorrectionTask::AddContainer	(	AliEmcalContainerUtils::InputObject_t	contType,
		std::string &	containerName,
		YAML::Node &	userNode,
		YAML::Node &	defaultNode
	)

private

Creates a new AliEmcalContainer derived container based on the requested type and the branch name set in the user and default YAML configuration and requested by a particular correction component. Supports the "usedefault" pattern to simplify setting the proper branch name. Any track input objects are created as track containers unless the branch is named "mcparticles". If this is problematic for your analysis, the track selection behavior of the track container can be disabled by setting the track selection to "kNoTrackFilter".

Note that the created container is adopted and managed by the Correction Task.

Parameters

[in]	contType	Type of the input object to add
[in]	containerName	Name of the container to create (as defined in the YAML configuration)
[in]	userNode	YAML Node corresponding to the user input object's configuration
[in]	defaultNode	YAML Node corresponding to the default input object's configuration

Returns: The created container

private

Adds the previously created input objects that are managed by the Correction Task into a correction component based on which input objects are requested in the YAML configuration by the component.

Parameters

[in]	component	The correction component to which the input objects will be added
[in]	inputObjectType	The type of input object to add to the component

void AliEmcalCorrectionTask::CheckForContainerArray	(	AliEmcalContainer *	cont,

private

Checks whether a container branch exists in the event. If it doesn't exist, then the branch is created automatically. Which this approach requires some care since no fatal error will be thrown when a nonexistent branch is requested, it also allows the creation of output branches just by selecting an unused branch name. For instance, this allows the clusterizer to easily create a new output branch.

Parameters

cont	The container which is requesting the branch
objectType	The type of the input object

void AliEmcalCorrectionTask::CheckForUnmatchedUserSettings ( )

private

Check each property defined in the user configuration file for a match to the properties in the default configuration file. The default configuration file should have all possible properties defined, so it can be treated as a reference. Thus, if there is a property that is defined in the user configuration that cannot be found in the default configuration, then it must be a typo and we should alert the user.

NOTE: This only checks settings in components. NOT variables defined at the root level, such as the pass or name! It also leaves the input objects unchecked, due to lacking a definitive list of possible settings.

Utilizes the stored ordered correction component names.

bool AliEmcalCorrectionTask::CheckPossibleNamesForComponentName	(	std::string &	name,
		std::set< std::string > &	possibleComponents
	)

private

Checks for a component name in a list of possible component names. This is necessary to search for the components that are associated with a given correction task and it's associated suffix. The comparison is done between strings, so some care is needed not to execute this function too often, especially for a large number of possible components

Parameters

name	Name to search for in the possible names
possibleComponents	Possible names of components that have been retrieved from the YAML file

Returns: True name in possible components name

bool AliEmcalCorrectionTask::CompareToStoredConfiguration	(	std::string	filename,
		bool	userConfig = `false`
	)		const

Compare the passed YAML configuration to the stored YAML configuration.

Parameters

filename	The filename of the YAML configuration to compare
userConfig	True to compare against the user configuration

Returns: True when the passed YAML configuration is the same as the stored YAML configuration

Definition at line 1418 of file AliEmcalCorrectionTask.cxx.

const std::vector<AliEmcalCorrectionComponent *>& AliEmcalCorrectionTask::CorrectionComponents ( )

inline

Direct access to the correction components.

Returns: std::vector of the correction components. Using this vector, the components and their settings can be modified as desired. However, keep in mind that whatever changes are made here will NOT be reflected in the stored YAML configuration.

Definition at line 113 of file AliEmcalCorrectionTask.h.

void AliEmcalCorrectionTask::CreateInputObjects ( AliEmcalContainerUtils::InputObject_t inputObjectType )

private

Steers the creation of all input objects of a selected type. In the case of clusters and tracks, AliEmcalContainer can be used, and a container is created for each requested object of the specified input object type. In the case of cells, an EMCal Correction Cell Container is created to handle the relevant information.

Normally, when properties are retrieved from the YAML configuration, the entire configuration is considered. However, here we only consider a subset in both the user and default configurations. In particular, the "inputObjects" section is selected and then all properties are drawn from this subset (the shared parameters are also retained so they can be used). Thus, it takes a bit more care to use this task, but it should be entirely transparent to the users - no functionality or expected flexibility is lost.

Parameters

inputObjectType Type of the input object(s) to create

void AliEmcalCorrectionTask::DetermineComponentsToExecute ( std::vector< std::string > & correctionComponents )

private

Determines which components to execute based on which are selected via specialization (ie suffix), as well as which are enabled and in what order they should be executed. The returned components in order of which they should be executed.

It is recommended to store the result, as it requires a large number of string comparisons and lookups in the YAML configuration, whose associated methods also utilize a number of string comparisons.

Parameters

[out] correctionComponents Names of the selected correction components in the order in which they should be executed.

void AliEmcalCorrectionTask::SetupContainer	(	AliEmcalContainerUtils::InputObject_t	inputObjectType,
		std::string	containerName,
		YAML::Node &	userNode,
		YAML::Node &	defaultNode
	)

private

Configures AliEmcalContainer derived tasks. Sets both general properties (such as min energy, etc), as well as container type specific properties (such as Non-linearity energy cut for a cluster container). Available options are enumerated in the general documentation related to the Correction Framework, available here.

Note for experts: This implementation explicitly calls particular functions, which is much more straightforward to understand and work with, but is less flexible. This means that any new options need to be implemented here by hand. An idea for a better implementation is mentioned in comments in the function for those who are interested. Once it is implemented, AliEmcalContainer derived classes could be entirely configured through YAML.

Parameters

[in]	inputObjectType	Type of the input object to configure
[in]	containerName	Name of the container to create (as defined in the YAML configuration)
[in]	userNode	YAML Node corresponding to the user input object's configuration
[in]	defaultNode	YAML Node corresponding to the default input object's configuration

		std::set< std::string > &	requestedContainers
	)

private

Creates the input objects containers requested by the components.

Parameters

[in]	inputObjectType	Type of the input objects to create
[in]	userInputObjectNode	YAML Node corresponding to the user input objects configuration
[in]	defaultInputObjectNode	YAML Node corresponding to the default input objects configuration
[in]	requestedContainers	Containers to be created

void AliEmcalCorrectionTask::UserCreateOutputObjects ( )

Reinitializes the YAML configurations if necessary and sets up for output from the correction components. The reinitialization is necessary if the object is streamed because yaml-cpp objects cannot be streamed. Instead, the YAML configuration is stored in strings and the nodes are recreated here from the string.

Note that the number of centrality bins is also set here in the case of a forced beam-type since this is how it was done in AliAnalysisTaskEmcal.

Definition at line 1030 of file AliEmcalCorrectionTask.cxx.

void AliEmcalCorrectionTask::UserCreateOutputObjectsComponents ( )

private

Calls UserCreateOutputObjects() for each component and ensures that the output from the correction components is eventually output by the correction task.

It also sets the number of centrality bins.

Bool_t AliEmcalCorrectionTask::UserNotify ( )

Executed when the file is changed. Also calls UserNotify() for each component.

Definition at line 1350 of file AliEmcalCorrectionTask.cxx.

bool AliEmcalCorrectionTask::WriteConfigurationFile	(	std::string	filename,
		bool	userConfig = `false`
	)		const

Write the desired YAML configuration to a file.

Parameters

filename	The name of the file to write
userConfig	True to write the user configuration

Returns: True when writing the configuration to the file was successful
