Innocens officina exemplar

Modus officinas simplex maxime solvit problema interfaciendi delectu.
Media pars Factory responsabilis est ad exsequendam logicam internam creandi omnes fructus.

2 Abstract Factory Pattern

Pattern Factory Abstractus est forma creandi exemplaria in designando et ad aedificandas familias productum adhibetur. Factory abstractissima est forma omnium formarum formarum generalissima et abstractissima exemplaria officinarum. Officinas abstractas refert ad officinam exemplaris adhibitam, cum multae sint functiones abstractae. Exemplar officinas abstractae interfaciem clienti praebere potest, permittens clientem ut res productas in pluribus familiis productas creare sine specifica productis specificatis. Quaelibet forma in officina exemplaris solutio certae quaestionis est. Methodus officinas ad multiplices structuras productorum series destinatur; dum forma officinarum abstractarum ad multiplices structuras domus productas spectat, cum multiplex series productorum intra familiam productam.

         Interfacem praebet ut seriem rerum interdependentium creando non specificat classes suas. Praecipuum propositum solvendi: Maxime solvendi electionem interfaciendi difficultates.

In exemplari officinas abstracto, cliens non iam responsabilis rerum creationis est, sed hanc responsabilitatem certis generibus officinarum relinquit.

Quattuor sunt partes officinas in abstracto exemplaris;abstrahere officinas partes、Imprimis officinas roles， abstractum productum persona，Imprimis producti muneribus.
