Add data extension class for FCCee Drift Chamber

[atolosadelgado]

Hi,

I went for the option of using a data extension for the drift chamber detector to store the parameters needed to later build the geometry and provide some functionalities as well. It seems these data and functionalities are useful at other stages (digitization and reconstruction).

I have developed the data extension class as part of the geometry within the k4geo repository, link, but I thought it could be useful to upstream it to DD4hep. What do you think?

• DDRec/DCH_info.h: Add data extension class for FCCee Drift Chamber. This class provides data storage and ancillary functionalities needed to build the geometry.

Hi Alvaro,

given the nature of these changes:
it is not necessary that the implementation is so tightly coupled to DDRec.
Please put the proposed changes into separate files (inside the DDRec package if you want) and it should be all OK.
Any client wanting to benefit then only has to include these headers.
Including it in the DetectorData.h/cpp files I think is slightly too intrusive.

Hi,

I have moved the data extension to a dedicated file. The class is header only. I noticed that for the other data extensions a dictionary is created here, do I have to create the dictionary as well? Why a dictionary is needed?

Thank you for your time :)

thanks @andresailer for the comments!

Brieuc wanted me to add another functionality to the class, I hope I can implemented it today, please do not merge it yet :)

We will keep the functionality where it is needed now. If in the future it is needed in more places we can upstream it here. Please review and merge at your earliest convenience :)
