Dear developers,
as I am currently working on the inheritance of some TPC classes from FairHit I stumbled upon a "const issue":
The constructors of FairHit and FairBasePoint take non-const references to TVector3's. This is a problem as soon as you want to implement e.g. a copy-constructor for a derived class MyClass : public FairHit that takes a const reference to MyClass as usual. If you then want to extract a data field and pass it to the constructor of FairHit, you actually need to manually remove the const-ness of that data with a cast or work around that by using the default constructor and set-functions.
Is there a reason to keep this or could we agree on changing the constructors?
Kind Regards,
Felix
