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 this pattern, becose of the strong typing of the language, does not make sense in Pascal. 2015-11-27 19:30 GMT-02:00, Mattias Gaertner <nc-gaert...@netcologne.de>: > > 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 > http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal > -- Luciano de Souza _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
