Okwanjula
Mu kitundu kya pulogulaamu ezigenderera ebintu, okutegeera abakyusakyusa okuyingira kikulu nnyo mu kukola koodi ennywevu era esobola okulabirira. Endowooza z’emitendera gy’okuyingira egy’obukuumi n’egy’obwannannyini zikola kinene mu kusiba, omusingi omukulu ogukakasa obulungi bw’embeera y’ekintu. Abakola batera okulwanagana n’okulonda wakati w’ebikyusa bino ebibiri okusobola okutebenkeza okutuuka n’obukuumi mu nkola zaabwe. Ekiwandiiko kino kigenda mu maaso n’okunoonyereza ku buzibu obutonotono obwa bammemba bennyini abakuumibwa , nga kinoonyereza ku biva mu nnimi ez’enjawulo ez’okukola pulogulaamu.
Okutegeera Ebikyusa Ebikwata ku Ntuukako
Ebikyusa okuyingira bye bigambo ebikulu ebikozesebwa mu nnimi ezigenderera ebintu okuteekawo okutuuka ku kiraasi, enkola, n’enkyukakyuka. Zinnyonnyola engeri bammemba b’ekibiina gye bayinza okufunibwa mu bitundu ebirala ebya pulogulaamu. Ebikyusa okuyingira ebisookerwako mulimu public , protected , private , ate oluusi default oba internal , okusinziira ku lulimi.
Ekikyusa Okuyingira mu Lujjudde
Bammemba abalangirirwa ng’ab’olukale batuukirirwa okuva mu kiraasi endala yonna. Omutendera guno ogw’okutuuka ku bantu gusobozesa okutuuka okusinga obunene naye guyinza okuvaako enkolagana ezitagenderere n’okukendeeza ku kusiba.
Omukyusa Okuyingira mu By’obwannannyini
Ekikyusa okuyingira okw'obwannannyini kikugira okulabika kwa bammemba ba kiraasi ku kiraasi mwe balangiriddwa. Kino kikakasa omutindo gwa waggulu ogw’okusiba, okulemesa kiraasi ez’ebweru okutuuka butereevu oba okukyusa bammemba bano.
Ekikyusa Okuyingira Okukuumibwa
Bammemba abalina omukyusa akuumibwa batuukirirwa mu kiraasi yaabwe era nga bayita mu kiraasi eziggiddwamu. This access level strikes a balance between private and public , okusobozesa subclasses okukozesa n'okugaziya emirimu nga bakuuma diguli ezimu ez'okusiba.
Private vs. Protected: Enjawulo enkulu
Enjawulo enkulu wakati okw’obwannannyini n’okukuumibwa w’abakyusakyusa okuyingira eri mu ddaala ly’okutuuka ku bibinja ebitonotono n’ebibinja eby’ebweru.
Okutuuka ku bantu mu Subclasses
Bammemba ab'obwannannyini tebatuukirirwa mu subclasses, ne bwe kiba nti subclass eri mu package oba module y'emu. Kino kitegeeza nti enkola oba enkyukakyuka ezirangiriddwa nga ez’obwannannyini teziyinza kusikira oba kukozesebwa butereevu mu kiraasi eziggiddwamu. Okwawukana ku ekyo, bammemba bennyini abakuumibwa batuukirirwa mu bibinja ebitono, ekisobozesa obusika n’enkula ez’enjawulo okukola obulungi.
Encapsulation n’Obukuumi
Okukozesa bammemba ab'obwannannyini kyongera ku encapsulation nga okweka ebikwata ku nkola okuva mu kiraasi endala zonna. Kino kiyinza okuziyiza okuyingirira okutali kwa kigendererwa naye kiyinza okukomya okugaziwa. Ku luuyi olulala, bammemba abakuumibwa babikkula ebimu ku bibinja ebitonotono, ne kibanguyira okugaziya naye nga kiyinza okuteekebwa mu kabi okusiba singa tebaddukanyizibwa n’obwegendereza.
Okukozesa mu Nkola
Okulonda wakati w’ebikuumibwa n’eby’obwannannyini kisinziira ku byetaago ebitongole ebya pulogulaamu ekolebwa.
Ddi lw’olina Okukozesa Eby’ekyama
Kozesa private nga oyagala okussa mu nkola encapsulation enkakali. Kino kirungi ku nkola z’omugaso oba enkyukakyuka ezitasaana kukyusibwa oba okutuusibwako ebweru wa kiraasi. Ekuuma embeera ey’omunda era n’ekakasa nti enkyukakyuka mu by’omunda mu kiraasi tezikosa kiraasi za bweru.
Ddi lw’olina Okukozesa Ebikuumibwa
Londa bammemba bennyini abakuumibwa ng’okola dizayini ya kiraasi egendereddwamu okusikira. Kino kisobozesa subclasses okuyingira n'okukyusa bammemba bano, okutumbula okuddamu okukozesa code n'okugaziya. Kyetaagisa nnyo mu nkola n’amaterekero g’ebitabo ng’okugaziya kye kikulu.
Eby’okulabirako mu nnimi ez’enjawulo ez’okukola pulogulaamu
Okutegeera engeri ennimi ez’enjawulo gye zissa mu nkola ebikyusa bino eby’okutuuka kikulu nnyo mu nkulaakulana y’ennimi ezisalasala n’okukozesa obusobozi obujjuvu obwa pulogulaamu ezigenderera ebintu.
Java
Mu Java, ekikyusa okuyingira ekikuumibwa kiwa okulabika munda mu package emu ne ku subclasses ne bwe ziba mu package ezenjawulo. Omukyusa ow'ekyama akugira okuyingira mu kiraasi elangirira yokka. Wano waliwo ekyokulabirako:
public class Omuzadde {
ekuumibwa void okulaga () {
// Enkola ekuumibwa
}
}
public class Omwana agaziya Omuzadde {
public void show () {
okulaga (); // Ebituukirirwa
}
}
C++
C++ egoberera enkola efaananako bwetyo, naye nga kwogasse n'okulaga emitendera gy'okuyingira mu busika. Bammemba abakuumibwa batuukirirwa mu bibiina ebiggiddwamu, so nga bammemba ab’obwannannyini tebatuukirirwa.
class Base {
ekuumibwa:
int ekuumibwaVar;
eby'ekyama:
int eby'obwannannyiniVar;
};
class Derived : public Base {
void omulimu () {
ekuumibwaVar = 1; // Ekituukirirwa
privateVar = 1; // Tekituukirirwa
}
};
Ebikwata ku nteekateeka ya Sofutiweya
Okulonda wakati w'ebikuumibwa n'eby'ekyama kukosa okukyukakyuka n'obukuumi bwa koodi yo.
Okugaziwa
Okukozesa bammemba bennyini abakuumibwa kyongera okugaziwa kwa kiraasi zo. Subclasses zisobola okusikira n'okukozesa bammemba bano okuzimba ku nkola eriwo awatali kukyusa base class.
Okulabirira
Overexposing class internals with protected kiyinza okuvaako okusoomoozebwa mu ndabirira. Enkyukakyuka mu kiraasi ya base ziyinza okukosa subclasses mu ngeri ezitategeerekeka, ekifuula codebase okukaluba okuddukanya.
Enkola Ennungi
Okunywerera ku nkola ennungi kikakasa nti okukozesa kwo okukyusakyusa okuyingira kyongera ku koodi yo okusinga okugiremesa.
Favor Composition Okusinga Obusika
Okwesigamira ennyo ku bammemba abakuumibwa kiyinza okulaga nti omuntu alina obusika obuyitiridde. Lowooza ku kukozesa composition okutuuka ku code reuse, ekitera okuvaamu code ekyukakyuka era esobola okulabirira.
Okutuuka ku bantu abatono ennyo
Okuwa omutendera omutono ogw’okutuuka ku bantu ogwetaagisa. Bwe kiba nti mmemba teyeetaaga kuyingizibwa mu bibiina ebitonotono, kifuule eky'ekyama . Enkola eno ekendeeza ku buzibu obuyinza okuvaamu ebizibu ebitali bigenderere.
Okunoonyereza ku mbeera
Okwekenenya embeera z’ensi entuufu ng’okulonda abakyusakyusa mu kutuuka kwalina ebikosa ebinene kiyinza okuwa amagezi ag’omuwendo.
Enkola z’Ensibuko eziggule
Enkola nnyingi zibikkula bammemba bennyini abakuumibwa okusobozesa abakola okugaziya kiraasi za base. Okugeza, mu nkola z’omukutu, kiraasi za base controller zitera okuba n’enkola ezikuumibwa eziyinza okukyusibwa okulongoosa enneeyisa.
Okumenya Ebyokwerinda okuva mu Overexposure
Wabaddewo embeera ng’okukozesa obubi enkola y’okuyingira mu ngeri ekuumibwa kyavaako eby’okwerinda okulemererwa. Subclasses zayingira era ne zikyusa base class internals mu ngeri ezitaali zigenderere, ne zireeta obutali butebenkevu n'okumenya.
Enkosa y’Ebifaananyi by’Olulimi
Ebintu ebikwata ku lulimi bisobola okukwata ku ngeri abakyusa okuyingira gye beeyisaamu era bisaana okulowoozebwako nga okola pulogulaamu za kompyuta.
Ebibiina by'emikwano mu C++
C++ eyanjulira endowooza ya kiraasi z’omukwano n’emirimu, ezisobola okutuuka ku bammemba ab’obwannannyini n’abakuumibwa aba kiraasi endala. Ekintu kino kyongera obuzibu mu kufuga okuyingira era kirina okukozesebwa mu ngeri ey’amagezi.
Okufumiitiriza mu Java ne C# .
Ennimi nga Java ne C# zikkiriza okufumiitiriza, ekiyinza okuyingira mu bammemba ab'obwannannyini mu kiseera ky'okudduka. Wadde nga kya maanyi, obusobozi buno busobola okulemesa okufuga okuyingira era bulina okukwatibwa n’obwegendereza.
Ebikyusakyusa mu kugezesa n’okutuuka ku bantu
Ebikyusa enkola y’okuyingira bisobola okukosa obusobozi bw’okugezesa koodi mu ngeri ennungi.
Okugezesa Bammemba ab'obwannannyini
Okugezesa bammemba ab’obwannannyini butereevu okutwalira awamu tekimalamu amaanyi. Wabula, ebigezo birina okussa essira ku nkolagana z’olukale. Naye kino oluusi kiyinza okukifuula okusoomoozebwa okutuuka ku kubikka koodi mu bujjuvu.
Bammemba Abakuumibwa mu Kugezesa
Okukozesa bammemba bennyini abakuumibwa kiyinza okwanguyiza okugezesa nga kikkiriza subclasses z'okugezesa okutuuka n'okukyusa enneeyisa ya base class. Enkola eno esobola okuba ey’omugaso naye erina okukozesebwa n’obwegendereza okwewala okuleeta okwesigamizibwa ku bikwata ku nkola.
Refactoring ne Access Modifiers
Refactoring code eyinza okuzingiramu okukyusa access modifiers okulongoosa ensengeka n'okulabirira.
Okukendeeza ku kutuuka ku bantu
Mu kiseera ky’okuddamu okukola ebintu, lowooza ku kukendeeza ku kutuuka ku bammemba okuva mu lukale oba abakuumibwa okudda mu bwannannyini singa okutuuka mu bugazi tekukyali kwetaagisa. Enkola eno eyongera ku encapsulation era ekendeeza ku bulabe bw’okukwatagana okutali kwa kigendererwa.
Okwewala Okumenya Enkyukakyuka
Bw'oba okyusa emitendera gy'okuyingira mu API ey'olukale, weegendereze okumenya enkyukakyuka. Okukendeeza ku kutuukirizibwa kuyinza okuleeta ensobi mu kukungaanya mu koodi esinziira ku API yo.
Emitwe egy’omulembe
Okunoonyereza ku ndowooza ez’omulembe kiyinza okwongera okutegeera n’okukozesa ebikyusakyusa okuyingira.
Ebikyusa Okutuuka mu Nkola z’Okukola
Enkola z’okukola dizayini zitera okulagira emitendera egy’enjawulo egy’okutuuka. Okugeza, enkola ya Singleton yeetaaga omuzimbi ow’obwannannyini okuziyiza instantiation okuva ebweru wa kiraasi.
Abakyusa mu Multithreading
Mu nkola ezirimu emiguwa mingi, abakyusakyusa okuyingira bakola kinene mu bukuumi bwa thread. Bammemba ab'obwannannyini basobola okuziyiza ensonga z'okuyingira mu kiseera kye kimu naye beetaaga okuyingira okukwatagana nga kugabanyizibwa mu mikutu gyonna.
Mu bufunzi
Okutegeera enjawulo wakati w’ebikyusa okuyingira ebikuumibwa n’eby’obwannannyini kyetaagisa nnyo mu kuwandiika koodi ennungi egenderera ebintu. Nga private ekakasa maximum encapsulation, protected own members bawa balance nga bakkiriza subclass okuyingira. Okusalawo mu ngeri ey’amagezi ku mitendera gy’okuyingira kyongera ku bukuumi bwa koodi, okulabirira, n’okugaziwa.
Nga banywerera ku nkola ennungi n’okulowooza ku biva mu buli mukyusa, abakola basobola okukola enzimba za pulogulaamu ennywevu era ezikyukakyuka. Okukozesa ekikyusa enkola entuufu ey’okuyingira bukugu bukulu obuyamba ku mutindo okutwalira awamu n’obuwanguzi bwa pulojekiti za pulogulaamu.
