Encapsulation - He aha ka keia? Encapsulation ma iaaiey

Encapsulation - keia mea kekahi o na kumu nui hiʻona ekolu o ka mea-aʻo i kaʻoihana iaaiey (oop). Na'ē aʻeʻelua - polymorphism a me ka hooilina. Together ka mea, e i ka PLO? Aieao i hoolakolako ia i ka laulā o nā hiʻona o ke kākau 'ana papahana i loko o kekahi' ōlelo, ka hoʻohana 'ana i kēia mau kumu ekolu. Mea-aʻo i kaʻoihana 'ōlelo, i ka huli, i ka pilikia e lakou hahai ia lakou.

oop kumu o ke

Mea-aʻo i kaʻoihana ma luna o iaaiey mau pouʻekolu o kona hanaia'na:

• Polymorphism, i mai i ka ninau o ana i ka ua iaaiey ōlelo epa me ka mea i loaʻa i ka pilina a me kekahi i kekahi, ma ka like me ke ano.
• Hooilina, e haawi ana i ka pane, pehea o ka stimulation o ka pono o reusable kivila.
• Encapsulation, i mea no ka pane ana i ka ninau o ka huna i ka manaʻo i wahi, a pela i kaʻikepili ano hoopono.

terminology

Encapsulation (iaaiey) - mea e hana ke kōkua o modifiers i mea e hūnā i na apana o ka hoopai karaima mai o ka hopena hoʻohana. Lalo ka mea, ma ka huli, 'o ia hoʻi ka mea haku polokalamu a me ka hoʻoilina ioauoa.

Ke pā like o ka manaʻo o "encapsulation"

I ka ho'ākāka 'ana hoʻomōakaaka ia ma ka encapsulation hana huna a pau a me ka hapa o ka? Ia? Aiiu kuhi. Ke pā like o ka manaʻo o "encapsulation" mea e manipulate hoʻohana modifiers. Kēia 'o ia hoʻi i ka mea haku polokalamu ke hooholo i ka waiwai, ki ina hana like, a me nā papa e e hamama no ka Client-ka papa, a me ka mea - i hunaiaʻi.

ke kōkua o modifiers

Aia i ke kōkua o modifiers, a, i waena o nā mea a pau, ua hiki no manipulyarivat encapsulation (Iawa iaaiey):

• lehulehu ( "Public" - lehulehu, e wehe ae komo) - kaʻana like 'ana o kaʻikena papa a me nā mea, a me ka mea ma waho ao nei;
• paulele i ka hoʻomana ( "prayvat" - paulele i ka hoʻomana, paulele i ka hoʻomana, i hūnāʻia ke kōkua o) - paa hou mai la ka hookipaia, i ka i loko o ka i ka loa i ke ku pono ana o ka mea mua kekahi. Ua 'oi aku ka hookipaia wale mai ka he papa;
• hoomaluia ( "protekted" - hoomaluia, hapa-i hūnāʻia ke kōkua o) - komo i ka he papa a me kona nā mea loaʻa;
• ka paʻamau - unspecified ke kōkua o modifier o ia hoʻi, e ka mahinaʻai / ano hiki ke 'ike no nā mea a pau i kaʻikena hoohui i loko o ka AEeAaOA.

In C # 'ōlelo ( "Si uea"), ma ka hou ana i ka luna (koe nae ka hope), eia nō modifiers:

• na ( "na" - kūloko ma ke kōkua o) - accessibility i loko o ka heʻaha kanaka, i loko o ka hookipaia ana i nā mea a pau nā hihia;
• kūloko ma hoomaluia ( "na protekted" - kūloko ma hoomaluia ke kōkua o) - hui ana o ka elua modifiers i ka kekahi ma ka i hoikeia mai na waiwai o nā o ia.

Ke kūlana o ka encapsulation

encapsulationʻano papa hana eliminates mawaho ole ma ka hoopai karaima a me ka hoʻohana kūpono 'ole o kaʻikepili i loko iho i loko o laila. Kēia Ua hooko ia e hoʻohuiʻia i ke karaima a me kaʻikepili i loko o hoʻokahi.

Mea a me ka encapsulation

Hoʻohuiʻia i ka manaʻo o ka lako polokalamu Module a me kaʻikepili i loko iho i loko o ke Kanawai, ua kapaʻia iaaiey o kekahi mea. Ke ae pā o kona pili me ka encapsulation mea ia ia ka papa hana e leie aku e malama, a hoʻopaʻa i ka pono o ka hana ana o keʻano papa hana.

I ka lanakila o ka encapsulation

Encapsulation - he ala e Nohie i ka hoʻopā'ālua kaʻina. Lehulehu laina o ka pā'ālua e "ma hope o ka ike weliweli", a ma ka papa kuhikuhiE papa hana e hele e kū'ē'ē 'he nui.

I ka manaʻo o kaʻikepili ka hoomalu ana

Encapsulation - ia mea no hoi heʻano papa hana i Cuticura i ka manaʻo o kaʻikepili ka hoomalu ana. Program kūpili mea-aʻo i kaʻoihana iaaiey ua kūkuluʻia ma luna o ke kumu o ka mea ka hapanui o kaʻikepili e e hunaia ke kōkua o modifier uku (paulele i ka hoʻomana, a pilikino) a hoomaluia (hoomaluia). Ke waho honua, ka Customer accidentally paha ka noonoo e, e ole hanaʻino i ka manaʻo o ka lako polokalamu Module. No ka mea, ma ka mea ka mea,ʻo ia ka mea nui paakiki i ole, a hiki ma ka manao, encapsulation - keia mea he rula loa maikai.

encapsulation pa alima

Class, like me ka walaʻauʻana pa alima o ka encapsulation, a wehewehe i kaʻikepili maupaʻa he kuhi, i mea hiki ke hana ma luna o kēia mauʻikepili. He mea no hoi i ke kumu no ka hana ana i ka mea. Ka la mahope, i ka huli, ua hōʻike mai iā ia e like me ka manawa.

I hoʻohana 'ia i ke kēia terminology:

• hoa - keia mea i ke karaima, a me nāʻikepili me i loko o ka papa;
• kula a me kekahi manawa DEBFULLNAME - ka ai-kapaia 'ikepili i Ho'ākāka' o ka papa;
• lala oihana - ka mea, aia no iloko olaila na kuhi iho. Member oihana - he mau inoa. A kūikawā hihia - ki ina hana like.
