Your approach is much better, but don't use casting is even better
when we working with a true object oriented, because casting is a
"procedural command" for the compiler.

OK, but you don't need generics either ;)

Marcos,
Your answer and the excelent article of Graeme clarify the question.
If I want to change the type of the instance, better is to use
generics. A factory is only a batch builder of the same objects.
Graeme, your article opened my mind. The mappings and the registers
caused me a very strong

You're right, use simply TDog.Create.
Why do you have a factory to create different types of animals

See my "Simple Factory Pattern" article. I've written about many other
design patterns too.

Yes, it works. But in this case, I don't understand the sense of the pattern.
If I need to do "TAnimalFactory.create(atDog) as Tdog", perhaps, it
would be better not to use a factory, doing simply "TDog.create".
I don't understand if I have implemented the pattern wrongly or if

One solution:
var
animal: TDog;
BEGIN
animal := TAnimalFactory.create(atDog) as TDog;
try
animal.bark;
finally
animal.free;
end;
END.

Hello all,
I'd like to understand how to implement the Factory Method pattern in Pascal.
In my example, there are four classes:
1. TAnimal - The parent and abstract class;
2. TDog and TCat - The specialized classes;
3. TAnimalFactory - The class which creates instances of animals,

Smart TVs are already either ARM or MIPS (both running Linux)...
