Enums vs Const vs Class Const in Delphi programming

Question

I have an integer field in a ClientDataSet and I need to compare to some values, something like this:

I can use const

const
  mvValue1 = 1;
  mvValue2 =          


        

Answer 1

I wouldn't say that class consts are not the Delphi way. It's just they have been introduced to Delphi quite recently, and a lot of books and articles you'll find on the internet were written before their introduction, and thus you won't see them widely used. Many Delphi developers (I'd say the majority) will have started using Delphi before they were made available, and thus they're not the first thing that one thinks about.
