Define and manage data analysis tasks.

Data analysis tasks are defined in the files $KVROOT/KVFiles/.kvrootrc and the user's $HOME/.kvrootrc, as in the following examples:

DataAnalysisTask:     Reconstruction
Reconstruction.DataAnalysisTask.Title:     Event reconstruction from raw data (raw->recon)
Reconstruction.DataAnalysisTask.Prereq:     raw
Reconstruction.DataAnalysisTask.Analyser:     INDRARawDataRecon

<p<blockquote>

Each task has a name ("Reconstruction"), a descriptive title ("Event reconstruction from raw data (raw->recon)"), a prerequisite type of data on which the analysis is performed ("raw"), and the name of a KVDataAnalyser plugin which is used to perform the analysis ("INDRARawDataRecon"). For a given dataset, only analysis tasks whose prerequisite data type is available can be performed.

+DataAnalysisTask:     ReconAnalysis
ReconAnalysis.DataAnalysisTask.Title:     Analysis of reconstructed events (recon)
ReconAnalysis.DataAnalysisTask.Prereq:     recon
ReconAnalysis.DataAnalysisTask.Analyser:     INDRAReconData
ReconAnalysis.DataAnalysisTask.UserClass:     yes
ReconAnalysis.DataAnalysisTask.UserClass.Base:     INDRASelector/TSelector
+Plugin.TSelector:  INDRASelector    KVSelector      KVIndra    "KVSelector()"

<p<blockquote>

This analysis task requires the user to supply an analysis class ("...UserClass: yes"); the class must be derived from a plugin base class, KVSelector, which is not defined in the basic KaliVeda library (see SetUserBaseClass() for details). It will be automatically loaded when required.

+DataAnalysisTask:     RawAnalysis
RawAnalysis.DataAnalysisTask.Title:     Analysis of raw data
RawAnalysis.DataAnalysisTask.Prereq:     raw
RawAnalysis.DataAnalysisTask.Analyser:     UserClass
RawAnalysis.DataAnalysisTask.UserClass:     yes
RawAnalysis.DataAnalysisTask.UserClass.Base:     INDRARawDataAnalyser
+Plugin.KVDataAnalyser:   INDRARawDataAnalyser   KVINDRARawDataAnalyser       KVIndra "KVINDRARawDataAnalyser()"

<p<blockquote>

This analysis task also requires the user to supply an analysis class ("...UserClass: yes"), but as the base class for the user's class is itself derived from KVDataAnalyser (via a plugin: see SetUserBaseClass() for details) it is the user's class which will be used to perform the analysis ("...Analyser: UserClass").

+DataAnalysisTask:     ReconIdent
ReconIdent.DataAnalysisTask.Title:     Identification of reconstructed events (recon->ident)
ReconIdent.DataAnalysisTask.Prereq:     recon
ReconIdent.DataAnalysisTask.Analyser:     INDRAReconData
ReconIdent.DataAnalysisTask.UserClass:     no
ReconIdent.DataAnalysisTask.UserClass.Base:     INDRAReconIdent/TSelector
+Plugin.TSelector:   INDRAReconIdent        KVReconIdent                 KVIndra   "KVReconIdent()"

<p<blockquote>

This analysis task does not require a user-supplied analysis class ("...UserClass: no") as it supplies a default analysis class to be used by the analyser (via a plugin: KVReconIdent. See SetUserBaseClass() for details).

Dataset-dependent analysis tasks

Certain characteristics (analyser plugin, base class for user analysis class) of analysis tasks can be "tuned" for different datasets. For example, to change the KVDataAnalyser plugin to use for the "Reconstruction" task for the dataset "INDRA_e494s":

INDRA_e494s.Reconstruction.DataAnalysisTask.Analyser:     IVRawDataRecon_e494s

<p<blockquote>

where the plugin is defined as:

+Plugin.KVDataAnalyser:   IVRawDataRecon_e494s   KVIVRawDataReconstructor VAMOS "KVIVRawDataReconstructor()"

◆ CheckUserBaseClassIsLoaded()

Bool_t KVDataAnalysisTask::CheckUserBaseClassIsLoaded ( )

virtual

This method checks that the base class for the user's analysis class is loaded. If this base class requires a plugin library to be loaded, it will be loaded. First we add any required extra ACliC include paths (taken from DataAnalysisTask.UserClass.ExtraACliCIncludes) If all is OK, returns kTRUE. Returns kFALSE if plugin cannot be loaded or class is simply unknown

◆ SetUserBaseClass()

void KVDataAnalysisTask::SetUserBaseClass ( const Char_t * base_name )

virtual

Set the class from which user's analysis class must derive. This is normally read in from the following environment variable:

TaskName.DataAnalysisTask.UserClass.Base: [base_name]

If base_name is not the name of a known (i.e. currently contained in the ROOT dictionary class table) class, it is assumed to be the uri of a plugin class. By default, we assume that the plugin extends the KVDataAnalyser class, but this can be changed using the following syntax:

TaskName.DataAnalysisTask.UserClass.Base: [uri]/[base class]

Example 1: The user analysis class for task "RawAnalysis" must derive from class KVIVRawDataAnalyser which is defined in library libVAMOS.so (not loaded by default):

RawAnalysis.DataAnalysisTask.UserClass.Base: IVRawDataAnalyser +Plugin.KVDataAnalyser: IVRawDataAnalyser KVIVRawDataAnalyser VAMOS "KVIVRawDataAnalyser()"

Example 2: The user analysis class for task "ReconIdent" must derive from class KVIVReconIdent (itself derived from TSelector) which is defined in library libVAMOS.so (not loaded by default):

ReconIdent.DataAnalysisTask.UserClass.Base: IVReconIdent/TSelector +Plugin.TSelector: IVReconIdent KVIVReconIdent VAMOS "KVIVReconIdent()"
