Bu i\u00e7eri\u011fimizde ise s\u0131radaki I <\/strong><\/em>harfine denk gelen\u00a0Aray\u00fcz Ayr\u0131m Prensibini(Interface Segregation Principle – ISP) ele alaca\u011f\u0131z.<\/p>\n

Biliyoruz ki, Interface’ler s\u0131n\u0131flar\u0131n anla\u015fmalar\u0131d\u0131r. Haliyle bir s\u0131n\u0131f\u0131n implement etti\u011fi bir Interface zorunlu \u015fekilde ilgili s\u0131n\u0131fa uygulanmaktad\u0131r. Hal b\u00f6yleyken s\u00f6z konusu Interface yetersiz ya da fazla geliyorsa, o s\u0131n\u0131f\u0131 da\u011f\u0131tmak yerine yeni bir Interface olu\u015fturmak daha makbuld\u00fcr. \u0130\u015fte, ISP’nin de ortaya koydu\u011fu mant\u0131k budur.<\/p>\n

Bu mant\u0131kla yola \u00e7\u0131karak ISP’nin, hemen hemen her farkl\u0131 yetenek i\u00e7in farkl\u0131 bir aray\u00fcz tan\u0131mlamas\u0131n\u0131 \u00f6nerdi\u011fini s\u00f6yleyebiliriz.<\/p>\n

Bir yandan soyutlama maksatl\u0131 kullanaca\u011f\u0131m\u0131z Interface yap\u0131s\u0131 i\u00e7erisinde her t\u00fcrl\u00fc metodu ve i\u015flemi bar\u0131nd\u0131rmam\u0131z, o Interface’i implement eden baz\u0131 s\u0131n\u0131flarda uygulanan elemanlar\u0131n kimileri Dummy Code(Sahte Kod) dedi\u011fimiz bir vaziyette niteliksiz yer i\u015fgal edeceklerdir. Yani ISP, bir s\u0131n\u0131fa hi\u00e7 gere\u011fi yokken filanca metodlar\u0131 ve i\u015flevleri implemente etmenin \u00f6n\u00fcne ge\u00e7ecek bir prensiptir.<\/p>\n

Tabi ki de \u00e7o\u011fu konuda oldu\u011fu gibi bu konuda da \u00f6rnek bir senaryo \u00fczerinden mevzuyu ele alaca\u011f\u0131z. Haliyle benim \u00f6rneklendirmem ordu \u00fczerine bir senaryodan ibaret olacakt\u0131r. D\u00fc\u015f\u00fcnelim ki, elimizde birden fazla tank\u0131m\u0131z olsun. Ve bu tanklar\u0131n \u00f6zelliklerini bar\u0131nd\u0131racak bir Interface’imiz olsun.<\/p>\n

$\"Aray\u00fcz$ <\/a>
\nEvet, g\u00f6rd\u00fc\u011f\u00fcn\u00fcz gibi tek bir Interface ile elimizdeki tanklar\u0131n \u00f6zelliklerini \u015fablonize ettik. Lakin, “Tank2” isimli tank\u0131m\u0131z\u0131n ate\u015f etme \u00f6zelli\u011finin olmad\u0131\u011f\u0131n\u0131 ve “Tank3” isimli tank\u0131m\u0131z\u0131n ise d\u00fc\u015fman ile mesafe \u00f6l\u00e7me yetene\u011fi olmad\u0131\u011f\u0131n\u0131 varsayarsak bundan dolay\u0131 “Tank2” i\u00e7in “AtesEt” ve “Tank3” i\u00e7in “DusmanIleMesafeOlc” isimli metodlar i\u015flevsiz kalacakt\u0131r.<\/p>\n

Al\u0131n size Dummy Code(Sahte Kod) durumu.<\/p>\n

\u0130\u015fte b\u00f6yle bir durumda ilgili metodlar\u0131 farkl\u0131 Interface’lere alarak daha do\u011frusu ‘aray\u00fczleri ay\u0131rarak’ bu soruna \u00e7\u00f6z\u00fcm bulabiliriz.<\/p>\n
