Hi, First of all, I did some research and found this: http://free-pascal-general.1045716.n5.nabble.com/Compiler-Warning-Constructor-should-be-public-td2825747.html But that did not convince me. So here is my situation and question. I have the following case: TBase = class public constructor Create; //VER-0 end; TDerived = class(TBase) private constructor Create(param1); //VER-1 public constructor Create; reintroduce; //VER-0' constructor Create(param1, param2); //VER-2 constructor Create(param1, param2, param3); //VER-3 end; My purpose is that while using TDerived, only VER-2 and VER-3 of the constructors should be used, VER-0 and VER-1 are used INTERNALLY by VER-2 and VER-3 and should NOT be used publicly.
Why not simply make it a procedure that is called by ver-2 and ver-3.If it cannot be called directly from external code, and will called only from inside a visible consructor, there is simply no reason to make this procedure a constructor. A simple procedure will do.
