Delphi: `procedure RaiseAbstractError(const aClass: TClass; const aMethodName: string);`

Posted by jpluimers on 2020/11/17

Needs the System.SysConst unit:

procedure RaiseAbstractError(const aClass: TClass; const aMethodName: string);
  // more explanatory than AbstractErrorProc();
  raise EAbstractError.CreateFmt('%s: method %s.%s', [SAbstractError, aClass.ClassName, aMethodName]);

It uses a TClass typed parameter so you can call it from non-static class methods (using Self as parameter value) in addition to instance methods (using ClassType as parameter value).
