CAF-RNTuple

This is a standalone test framework to test the persistence of CAF objects in RNTuple. Please follow the instructions below to build and run this code:

Requirements

1. Install ROOT (master version). Note that RNTuple is still in development (as of this writing).
2. CMakeLists (version > 3.20)
3. duneanaobj (https://github.com/DUNE/duneanaobj.git) which has CAF objects (or Standard Record Objects).

Minimal Installation of the Package with external packages (duneanaobj)

git clone --recurse-submodules https://github.com/hep-cce2/CAF-RNTuple.git
cd CAF-RNTuple
mkdir build
cd build
cmake -DCMAKE_MODULE_PATH=/path/to/ROOTConfig.cmake ..
make -j$(nproc)

This will download CAF test framework and the duneanaobj package.

CAF-RNTuple

CAF-RNTuple is the package that allows to test the persistence of CAF objects in RNTuple (and TTree). It depends upon the standalone duneanaobj build.

CMakeLists.txt Assumes that the environment variables are setup according to setup_dunecaf.sh

CAF-RNTuple/test

This directory contains the test codes for CAF object persistence in TTree and RNTuple

Test_CAF.cxx CAF Objects persist in TTree

Test_CAFSimple CAF Objects persist in RNTuple

simple_converter.C FlatCAF written in TTree are written into RNTuple using RNTupleConverter

CAF-RNTuple/utilities

StandardRecordObjects This function basically fills each and every StandardRecord members. The APIs here are called by test codes in CAF-RNTuple/test

FillStandardRecordObjects This function fills the members of StandardRecord in TTree or RNTuple by calling the StandardRecordObjects. This goes inside the event loop of both TTree and RNTuple.

CAF-RNTuple/external Git will download the duneanaobj and build the library here.
