Introduction

AC++ is an Object-Oriented general analysis framework for use in the many phases of HEP computing, from online triggering and monitoring, to offline production and subsequent processing. Function is organized into modules, which can be scheduled at run-time for execution. The framework provides access to persistent event data through input modules. Output modules are written to store the reconstructed data in the selected manner. Input and output modules that read and write YBOS data using the TRYBOS package have been written. You can browse examples that use these modules, or you can use example 1 on the Run II Physics Workshops page in order to link your own example. In the near future this example will be updated to use the new EDM. The framework will also be responsible for providing access to the detector geometry and calibration information.

Documentation

• Current documentation
  • An overview document titled A users guild to the AC++ Framework (HTML) . A printable postscript version is also available.

  • A Commands Reference Manual This now points to the original manaual provided by BaBar. In the near future it will point to an updated document for CDF.

  • In AC++ a user no longer "writes a talk-to". Instead your module class defines a number of commands that it takes input from. The document which discusses this topic and goes through an example is a CDFnote, Creating Talk_to Menus for AC++.

  • Reference manual for gnu readline

  • Reference manual for gnu history

  • A talk on Framework Modules was given at the 19-Feb-1997 infrastructure meeting.

  • An overview talk on the AC++ Framework that was given at the 13-Nov-1996 godparent review meeting.

Plans

A collaborative agreement has been made with members of BaBar and CLEO. They propose modifying Framework to provide module support that is now missing. Calibrarion and Geometry needs to be handled in a better way and the proposed solution is to use the CLEO Frame code, which was reported on at CHEP. To follow these developments see the HyperText forum devoted to this topic.
