I couldn't find any reference on roottalk to this subject yet, so here I
go.
I noticed that in the root classes (including TObject) almost never
memberfunctions which don't (and shouldn't!) change datamembers of a class
are declared constant.
For example most 'getters' should be declared constant (Except in
the exceptional case where you want a user of a class to be able to change
a datamember (which usually indicates an 'ill formed' (i.e. non OO)
program.)) Another example is for example the TObject::Print() member
which (at least in my opinion) should not change the object.
Of course C++ does not force anyone to declare memberfunctions
constant if they in fact don't change the object. I do think it
is a sort of convention in structered/OO programming in C++ though. I see
that this might not be an issue of the highets priority but I think it
should be changed in the (near) future.
Anybody have (other) opinions about this?
