Links to code
The description below includes links to the code contained in this
package. This
version
of the code may not be the most recent.
This package includes classes for reading and writing the standard global
tracking ntuple and the global tracking and event pieces of the reco analyze
ntuple. It also provides a class for converting from reco analyze to standard
format. All ntuples are root TTree's.
The physical components include:
- RanBranchName (

source,
test )
- TreeData (

- StdMcRecoData (

- EventData (

- RanMcData (

- RanMcRecoData (

- RanMcRecoData (

- RanToStcConverter (

This package depends on root.
The classes defined in the above components are described below.
Each class is defined in a component of the same name unless otherwise
indicated.
The descriptions are brief.
See the header files for details.
RanBranchName returns information about a global tracking branch of the
reco analyze ntuple. The type and properties of the branch are deduced
from the branch name.
TreeData is a base class which provides an
interface for accessing selected data from a ROOT tree.
In general subclasses will be able to read data from or write data to
a root ntuple.
StdMcRecoData is a subclass which provides
access to the data in the standard GTR ntuple (not the version in
reco analyze).
EventData is a subclass which provides access to the event data
branch of the reco analyze ntuple.
RanMcData is a subclass which provides access to GTR Monte Carlo track
branch of the reco analyze ntuple.
RanRecoData is a subclass which provides access to GTR reconstructed track
branch of the reco analyze ntuple.
RanRecoData is a subclass which provides access to GTR MC-reco match
branch of the reco analyze ntuple.
RanToStdConverter converts reco analyze GTR branches (MC, reco or
MC-reco match) to the standard GTR ntuple.
