Detailed Description

Load a ttbar event reconstruction code based on the same.

Names for reconstruction (rather than selection) should start with "RECO:" so that we can tell them apart.

Why is this a class? So that ROOT can load it at run-time! The only important function is the initTool one, after that has been called then this class can be safely disposed of.

Note that the name of this tool is the name of the package with the word Loader after it. That's important so the main code can find the tools that this package provides! For the same reason it inherits from top::ToolLoaderBase.

initTool()

top::EventSelectorBase * top::TopEventReconstructionToolsLoader::initTool ( const std::string &  name, const std::string &  line, TFile *  outputFile, std::shared_ptr< top::TopConfig >  config, EL::Worker *  wk = nullptr  )

virtual

Some sort of factory that can create the tool you need given a string.

Parameters

name	The name of the tool to load, e.g. RECO:KLFITTERLJETS.
line	Not used here yet, but could be used to send configuration options to the tool.
config	The TopConfig object, which is needed by the KLFitterTool
outputFile	Not used here, but could be used so the tool has direct access to the output file.
wk	Not used, but needed by EventLoop for some of the selection tools.

Returns

A pointer to a fully initialised and ready to use tool.

Implements top::ToolLoaderBase.
