Kontrol\u0117s apvertimas<\/h1>\n

Valdymo inversija (IoC) yra projektavimo modelis, leid\u017eiantis k\u016br\u0117jams ra\u0161yti laisvai susietas ir modulines kodas<\/a>. Tai programavimo paradigma, kurioje taikomosios programos vykdymo srauto kontrol\u0117 apver\u010diama nuo tradicinio po\u017ei\u016brio, kai taikomosios programos kodas kontroliuoja vykdymo sraut\u0105. Vietoj to, IoC leid\u017eia sistemai arba konteineriui kontroliuoti vykdymo sraut\u0105, pateikiant priklausomybes taikomosios programos kodui.<\/p>\n

Pagrindinis IoC tikslas - suma\u017einti taikomosios programos komponent\u0173 ir priklausomybi\u0173 susiejim\u0105. Taikant tradicin\u012f po\u017ei\u016br\u012f, taikomosios programos kodas yra atsakingas u\u017e priklausomybi\u0173 k\u016brim\u0105 ir valdym\u0105. Toks po\u017ei\u016bris lemia glaud\u0173 komponent\u0173 susiejim\u0105, tod\u0117l sud\u0117tinga pri\u017ei\u016br\u0117ti ir testuoti program\u0105. Naudojant IoC, taikomosios programos kodas tik deklaruoja savo priklausomybes, o j\u0173 k\u016brimu ir valdymu r\u016bpinasi sistema arba konteineris.<\/p>\n

IoC modelis \u012fgyvendinamas naudojant du pagrindinius metodus: Priklausomyb\u0117s \u012fterpimas (DI) ir paslaug\u0173 ie\u0161kiklio modelis. Priklausomybi\u0173 \u012f\u0161virk\u0161timas - tai metodas, kai objekto priklausomybes \u012f j\u012f \u012f\u0161virk\u0161\u010dia sistema arba konteineris. Paslaug\u0173 ie\u0161kiklio modelis - tai metodas, kai taikomasis kodas u\u017eklausia priklausomybi\u0173 i\u0161 centrinio paslaug\u0173 ie\u0161kiklio, kuris gr\u0105\u017eina atitinkam\u0105 priklausomyb\u0119.<\/p>\n

IoC naudojimo privalumai yra \u0161ie: didesnis programos moduliavimas, testavimas ir prie\u017ei\u016bra. Suma\u017einus komponent\u0173 susiejim\u0105, juos lengviau modifikuoti ar pakeisti nedarant poveikio likusiai programai. Naudojant IoC taip pat lengviau ra\u0161yti taikomosios programos vienet\u0173 testus.<\/p>\n

IoC pla\u010diai naudojamas \u0161iuolaikin\u0117se programin\u0117s \u012frangos k\u016brimas<\/a>, o daugelis karkas\u0173 ir bibliotek\u0173 j\u0105 palaiko. Kai kurie populiar\u016bs IoC konteineriai yra \"Spring\", \"Guice\" ir \"Autofac\". Naudodami \u0161iuos konteinerius k\u016br\u0117jai gali sutelkti d\u0117mes\u012f \u012f taikomosios programos verslo logikos ra\u0161ym\u0105, o konteineris pasir\u016bpina priklausomyb\u0117mis.<\/p>\n

Apibendrinant galima teigti, kad valdymo apvertimas yra galingas projektavimo modelis, leid\u017eiantis k\u016br\u0117jams ra\u0161yti modulin\u012f, testuojam\u0105 ir pri\u017ei\u016brim\u0105 kod\u0105. Naudodami IoC k\u016br\u0117jai gali suma\u017einti programos komponent\u0173 susiejim\u0105, tod\u0117l j\u0105 lengviau modifikuoti ir pri\u017ei\u016br\u0117ti. IoC pla\u010diai naudojamas kuriant \u0161iuolaikin\u0119 programin\u0119 \u012frang\u0105, o daugelis karkas\u0173 ir bibliotek\u0173 j\u012f palaiko.<\/p>","protected":false},"excerpt":{"rendered":"
