More Complete MakeClass Example?

[jfcaron]

I’ve been reading http://root.cern.ch/download/doc/ROOTUsersGuideHTML/ch12s21.html and one of the early passages is:

It is clear that you want to be as independent as possible of the header file (i.e. MyClass.h) generated by MakeClass. The solution is to implement a derived class, for example MyRealClass deriving from MyClass such that a change in your Tree or regeneration of MyClass.h does not force you to change MyRealClass.h. You can imagine deriving several classes from MyClass.h, each with a specific algorithm.

I would like to request an addition to this User Guide section which outlines this example of deriving MyRealClass from MyClass. It might just need an extra line or two explaining how this would work.

Hi Jean-François,

Besides the fact that we recommend using MakeSelector or MakeProxy rather than MakeClass, the point is still taken that we need to expand the documentation in this area.

I added this to our official list of things to improve (sft.its.cern.ch/jira/browse/ROOT-5305).

Thanks,
Philippe.
