Hi there! I''m wondering if there''s anything to compare with "class function" for member variables, like with "static" in C++ or Java. The closest I''ve managed is variables after the implementation part, like this:
unit something;
interface
type
TSomething = class
protected
class function GetMyVar: Integer;
public
end;
implementation
var
FMyVar: Integer = 0; // the static variable
class function TSomething.GetMyVar: Integer;
begin
Result := FMyVar;
end;
end.
The class function is for descended classes. Of course, because the variable is declared after the implementation section, it can''t be seen outside the unit without such a function.
You can make a public property to access the variable if that''s what you want.
This method works fine, and I haven''t run into any problems with it, but I just wondered if there was a specific keyword for this.
