Detailed Description

Steven Schramm
February 2014.

Updated for Run 3 by Bill Balunas March 2020

Tool to calculate the jet vertex fraction (JVF) JVF is a vector<float> with respect to all vertices

Calculation requires three main types of information

1. Vertex container for the event (from evtStore), which the JVF vector is aligned with
2. Tracks associated to the input jet (in the jet aux store)
3. Track vertex association object (from evtStore)

Using this information, the procedure can be broken into three main steps:

1. Retrieve necessary information
2. Helper method to create the full vector given the information
3. Helper method to create the JVF value for one vertex given the information

Properties: VertexContainer - name of the vertex container AssociatedTracks - name for attribute holding the list of associated tracks TrackVertexAssociation - name for the container holding the track-vertex associations TrackSelector - tool to select tracks (none ==> no selection) JVFName - name for the JVF array attribute (default is "JVF")

getKey()

SG::sgkey_t asg::AsgTool::getKey ( const void * ptr ) const

Get the (hashed) key of an object that is in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::TEvent both provide ways for getting the SG::sgkey_t key for an object that is in the store, based on a bare pointer. But they provide different interfaces for doing so.

In order to allow tools to efficiently perform this operation, they can use this helper function.

Parameters

ptr	The bare pointer to the object that the event store should know about

Returns

The hashed key of the object in the store. If not found, an invalid (zero) key.

getProperty()

Dummy implementation of the initialisation function.

It's here to allow the dual-use tools to skip defining an initialisation function. Since many are doing so...

inputHandles()

virtual std::vector< Gaudi::DataHandle * > AthCommonDataStore< AthCommonMsg< AlgTool > >::inputHandles ( ) const

Return this algorithm's input handles.

We override this to include handle instances from key arrays if they have not yet been declared. See comments on updateVHKA.

modify()

msg_level_name()

const std::string & asg::AsgTool::msg_level_name ( ) const

inherited

A deprecated function for getting the message level's name.

Instead of using this, weirdly named function, user code should get the string name of the current minimum message level (in case they really need it...), with:

MSG::name( msg().level() )

This function's name doesn't follow the ATLAS coding rules, and as such will be removed in the not too distant future.

Returns

The string name of the current minimum message level that's printed

Definition at line 101 of file AsgTool.cxx.
