One solution: var animal: TDog; BEGIN animal := TAnimalFactory.create(atDog) as TDog; try animal.bark; finally animal.free; end; END. Mattias ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org

[fpc-pascal] Implementing Factory Method with Pascal

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, having

Re: [fpc-pascal] Implementing Factory Method with Pascal

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

type IBarkable = interface(IInterface) ['{B241068F-2ED9-43C7-066B-778B94CB58F9}'] procedure Bark; end; TAnimal = class(IInterface) end; TDog = class(TAnimal, IBarkable) public procedure Live; override; procedure Bark; end; and later ... if Animal is IBarkable then
