Indlela entsha Ifayela.DynamicVersions Ibuyisela uhlu lwezinguqulo eziguquguqukayo ezichazwe kufayela le-ELF. Indlela entsha File.DynamicVersionNeeds Ibuyisela uhlu lwezinguqulo eziguqukayo ezidingwa yileli fayela le-ELF ezichazwe kwezinye izinto ze-ELF. Ekugcineni, izinkambu ezintsha I-Symbol.HasVersion и I-Symbol.VersionIndex khombisa inguqulo yophawu.

Ukufaka ikhodi

Izixhumi ezibonakalayo ezimbili ezintsha UmbhaloAppender и I-BinaryAppender zethulwe ukwengeza umbhalo noma ukumelwa okumbambambili kwento kucezu lwebhayithi. Lezi zixhumanisi zihlinzeka ngokusebenza okufanayo ne UmbhaloMarshaler и I-BinaryMarshaler, kodwa esikhundleni sokunikeza ucezu olusha isikhathi ngasinye, banezela idatha ngokuqondile ocezwini olukhona. Lezi zixhumanisi zisetshenziswa okwamanje izinhlobo ezijwayelekile zelabhulali esezivele zisebenzise i-TextMarshaler kanye/noma i-BinaryMarshaler.

umbhalo wekhodi/json

Uma wakha, inkambu yesakhiwo enenketho entsha ye-omitzero kumaka wenkundla yesakhiwo izokhishwa uma inani layo linguziro. Uma uhlobo lwenkambu lunendlela ye-bool ye-IsZero(), izosetshenziswa ukuze kutholwe ukuthi ingabe inani linguziro. Uma kungenjalo inani lizoba uziro uma likhona inani elingenalutho lohlobo lwayo. Ithegi yenkundla ye-omitzero ihlanzekile futhi ayinaphutha kangako kune-omitempty uma inhloso kuwukushiya amanani angenalutho. Ikakhulukazi, ngokungafani ne-omitempty, i-omitzero ishiya ama-zero isikhathi.isikhathi amanani, okuwumthombo ovamile wezinkinga.

Uma kokubili omitempty kanye ne-omitzero kucacisiwe, inkambu izokhishwa uma inani lingenalutho noma uziro (noma kokubili).
