Paul Scherrer Institut 5232 Villigen PSI ROME / / Matthias Schneebeli Introduction to ROME

Paul Scherrer Institut 5232 Villigen PSI ROME / / Matthias Schneebeli Features Tool for Event based Data Analysis Fully Object Oriented Root based Full connection to the Midas Environment Online and Offline Based on Tasks and Folders for a good Data and Program Structure Experiment independent Base Classes Experiment dependent Classes are generated out of simple XML-Files The Users write only experiment specific code (physics) Administrative code is implemented in the generated code Self Documenting Code Self Linking Project

Paul Scherrer Institut 5232 Villigen PSI ROME / / Matthias Schneebeli Objects Folders Objects, where data is stored in Stores the data of one detector (or sub detector) component Hierarchically arranged Data inside of Folders is structured Tasks Tasks are objects, which provides actions They make calculations Store and read data in folders Fill trees and histograms Hierarchically arranged. Task also own histograms Trees Data Objects : only written, never read Used to write data on files Histograms Graphical Data Objects : only written Belong to one Task

Paul Scherrer Institut 5232 Villigen PSI ROME / / Matthias Schneebeli The ROME Environment 5 experiment independent ‘ROME’-Classes o Base classes for the generated, experiment dependent classes. ROMEBuilder o Builds all experiment dependent classes out of simple XML Files o XML files describe Tasks, Folders, Trees, Histos and the Database. o Links the generated project o Documents the generated project ROME classes XML File ROME classes Exp. classes ROMEBuilder Executable Documentation Project ROME Environment

Paul Scherrer Institut 5232 Villigen PSI ROME / / Matthias Schneebeli ROME classes Tasks Classes in the Generated Project The generated project consists of Task classes o Implement 5 user methods : Init(), BeginOfRun(), Event(), EndOfRun(), Terminate(). Folder classes o Define the data structure of the folders. Analyzer class o Main class. Contains the folders, the trees and the data base. EventLoop class o Implements the event loop. The event loop calls the user methods of the tasks. ROME classes Folders EventLoop Analyzer Folder Handles Trees Data base fAnalyzer
