Runtime Type Information (RTTI)/ru
Информация времени выполнения (RTTI) может быть использована для получения мета-данных в приложениях Pascal.
Преобразование перечислимого типа в строку
Можно использовать RTTI для получения строки из перечисляемого типа.
type
TProgrammerType = (tpDelphi, tpVisualC, tpVB, tpJava) ;
uses TypInfo;
var
s: string;
begin
s := GetEnumName(TypeInfo(TProgrammerType), integer(tpDelphi));
// Здесь s = 'tpDelphi'Вы также можете сделать это, без использования RTTI:
program noRTTI;
type
TProgrammerType = (tpDelphi, tpVisualC, tpVB, tpJava) ;
var
s: string;
begin
writestr(s,tpDelphi);
writeln(s);
end.См. также
