Isinxulumanisi senkqubo Object ebomini

Into ebomini senkqubo - indlela kufutshane kangangoko kunokwenzeka yokuziphatha kwethu. Lusetyenziswa ukwandiswa yendalo ezintsha ngaphambili enxulumene nophuhliso lweelwimi kweenkqubo. Ukuba sithethe lwenkqubo olucwangcisiweyo, ngoko oku kubaluleke kakhulu structured ngaphezu uguqulelo ngaphambili, ukongeza, oko ngakumbi abstract, ngakumbi yemodyuli. Sele kwenziwe iinzame disengage ze uhambisae iziqalelo kweenkqubo yenqanaba ekuthiwa-ngaphakathi.

Into ebomini kweenkqubo kukusebenzisa uphuhliso lweelwimi ezizodwa. Zidla luphawulwa iinkalo ezintathu ezingundoqo:

- encapsulation, okt indibanisela iirekhodi kunye nemisebenzi kunye neenkqubo, kwakunye izakhi amasimi data iirekhodi, ukwakha uhlobo olutsha ngokupheleleyo sedata, ebizwa into;

- lilifa, inkcazelo into kuthetha ukusetyenziswa kwayo okwalandela ukwakha uluhlu izinto badalwa bakwazi ukuvelisa izinto ezintsha malunga zabefundisi, ngokunjalo okuthetha ikhowudi yofikelelo kwaye avelise ulwazi malunga nazo zonke izinto;

- polymorphism, oko kukuthi, ukukwazi isabelo izenzo igama elifanayo, eya kuthi ke kwabelwana phezulu kwaye phantsi kuluhlu into, kwaye lwemigangatho yabasemagunyeni ukuphunyezwa nganye into isenzo ngale ndlela kuya kuba luxanduva oko kulungileyo kuye.

Into ebomini iinkqubo Ugcino ibonelela iseti epheleleyo lwezixhobo lwenkqubo, ziphakathi leyo: modularity olukhulu abstract ecwangcisiweyo, eyakhelwe-ngaphakathi ubuchule ukuphinda asetyenziswe. Zonke ezi mpawu kunganxulunyaniswa ikhowudi, leyo oluhleliweyo, kulula ngakumbi ngokubhekiselele kwinkonzo kunye neemeko ngeemeko kakhulu ngakumbi. Amaxesha amaninzi, zokuhlela into ebomini lusenza ushiye bucala imigwebo ezithile malunga lwenkqubo iminyaka emininzi ithathwa umgangatho. Noko ke, xa oku kwenziwe, hayi kubonakala inkqubo yophuhliso nzima kangaka, yaye kubonakala ukuba ecacileyo sixhobo sigqibeleleyo kwiintlobo ngeentlobo zemisebenzi, beninikela engxakini enkulu software engenamsebenzi.

Ukuba wenza umsebenzi wethu, umzekelo, ukufunda senkqubo into-abemi PHP, kuyimfuneko ukuba ukulahla kwaye ayilibale into oyaziyo ngayo ngaphambili, yaye weza isifundo sakhe ekuqaleni. Indlela kuphela uya kuba nako ukubona zonke iinkcukacha zale ndlela ukuphonononga ezimqoka neempawu. isinxulumanisi senkqubo into ebomini asiyiyo yodwa indlela, ungaphezulu njenge continuum of izimvo swi wokuqulunqa ikhowudi ecocekileyo. Le emafini isebenza ngemigaqo ezininzi ezahlukeneyo, xa uthelekisa kunye netoliki, lo gama ngesantya iphezulu kakhulu. Abadibanisi ijoliswe ekuphuhliseni naziphi iimveliso software lilungile, kunokuba kumqolo elilinganiselweyo imisebenzi.

iiklasi

Phambi kokuba lwenziwe into ebomini iilwimi iinkqubo xa izinto ezininzi ziye utsha imfuneko ezongeziweyo iintlobo data ngaphezu amanani lokwenene inani elipheleleyo, variables itekisi kunye variables seBhulin. Yenze kube nzima ukusebenza kunye kwimiboniso data elipheleleyo. Nantso into wasebenzisa iiklasi e iingqiqo OOP oko. Nezakhiwo ezinjalo kwaba lula kakhulu ukuba asebenze; ngokuba ngoku kuba izinto ezifanayo akukho mfuneko yokuba babhalise ezininzi imigca ikhowudi ukufumana into enokuveliswa ngokuzenzekelayo. Kuba ekwinqanaba elisezantsi iilwimi lokuprograma indlela enjalo kubonakala kunzima kakhulu, kodwa kwisigaba entsha yophuhliso ukulisebenzisa kakhulu kamnandi.
