Go’da Haritalar: Kapsaml\u0131 Bir Rehber<\/h2>\n

Go programlama dilinde haritalar (maps), anahtar-de\u011fer \u00e7iftlerini depolamak i\u00e7in kullan\u0131lan temel veri yap\u0131lar\u0131ndan biridir. Python’daki s\u00f6zl\u00fckler (dictionaries), Java’daki HashMap’ler veya JavaScript’teki nesneler gibi d\u00fc\u015f\u00fcn\u00fclebilirler. Haritalar, verileri organize etmenin, eri\u015fmenin ve i\u015flemenin esnek ve verimli bir yolunu sunar. Bu makalede, Go’daki haritalar\u0131n temellerini, nas\u0131l kullan\u0131lacaklar\u0131n\u0131, geli\u015fmi\u015f \u00f6zelliklerini ve pratik uygulamalar\u0131n\u0131 detayl\u0131 bir \u015fekilde inceleyece\u011fiz.<\/p>\n

Go’da Haritalar\u0131n Temelleri<\/h3>\n

Bir harita, benzersiz anahtarlar arac\u0131l\u0131\u011f\u0131yla eri\u015filebilen de\u011ferlerin bir koleksiyonudur. Her anahtar\u0131n yaln\u0131zca bir de\u011fere kar\u015f\u0131l\u0131k geldi\u011fi bir ili\u015fkilendirme (association) s\u00f6z konusudur. Go’da haritalar, map<\/code> anahtar kelimesi ile tan\u0131mlan\u0131r ve belirli bir anahtar t\u00fcr\u00fc ile de\u011fer t\u00fcr\u00fc belirtilir.<\/p>\n

Harita Tan\u0131mlama ve Ba\u015flatma<\/h4>\n

Bir harita tan\u0131mlaman\u0131n birka\u00e7 yolu vard\u0131r:<\/p>\n

1. make<\/code> Fonksiyonu ile:<\/strong> Bu, haritalar\u0131 ba\u015flatman\u0131n en yayg\u0131n yoludur.<\/p>\n

\/\/ string anahtarlar\u0131 ve int de\u011ferleri olan bir harita\n    var myMap map[string]int\n    myMap = make(map[string]int)\n\n    \/\/ Tek sat\u0131rda tan\u0131mlama ve ba\u015flatma\n    anotherMap := make(map[string]string)<\/code><\/pre>\n
    make<\/code> fonksiyonu, iste\u011fe ba\u011fl\u0131 olarak haritan\u0131n ba\u015flang\u0131\u00e7 kapasitesini de belirtebilir. Bu, harita b\u00fcy\u00fcd\u00fck\u00e7e yeniden tahsis edilme say\u0131s\u0131n\u0131 azaltarak performans\u0131 art\u0131rabilir.<\/p>\n
\/\/ Ba\u015flang\u0131\u00e7 kapasitesi 10 olan bir harita\n    capacityMap := make(map[int]bool, 10)<\/code><\/pre>\n
2.  Harita Literaileri ile:<\/strong> Haritalar, do\u011frudan de\u011fer atayarak da ba\u015flat\u0131labilir.<\/p>\n
\/\/ Anahtar-de\u011fer \u00e7iftleri ile ba\u015flat\u0131lm\u0131\u015f bir harita\n    literalsMap := map[string]float64{\n        "pi":    3.14159,\n        "e":     2.71828,\n        "phi":   1.61803,\n    }<\/code><\/pre>\n
    Bu y\u00f6ntem, haritaya \u00f6nceden bilinen baz\u0131 de\u011ferleri eklemek istedi\u011fimizde kullan\u0131\u015fl\u0131d\u0131r.<\/p>\n
3.  nil<\/code> Haritalar:<\/strong> Bir harita tan\u0131mlan\u0131p make<\/code> ile ba\u015flat\u0131lmazsa, varsay\u0131lan olarak nil<\/code> olur. nil<\/code> bir haritaya eleman eklemeye \u00e7al\u0131\u015fmak bir \u00e7al\u0131\u015fma zaman\u0131 hatas\u0131na (panic) neden olur.<\/p>\n
var nilMap map[string]int \/\/ Bu harita nil'dir\n    \/\/ nilMap["key"] = 10 \/\/ Bu hata verir!<\/code><\/pre>\n
    nil<\/code> bir haritadan eleman okumak ise hataya neden olmaz, ancak s\u0131f\u0131r de\u011ferini d\u00f6nd\u00fcr\u00fcr (de\u011fer t\u00fcr\u00fcn\u00fcn s\u0131f\u0131r de\u011feri).<\/p>\n
Haritalara Eleman Ekleme ve G\u00fcncelleme<\/h4>\n
Bir haritaya eleman eklemek veya mevcut bir eleman\u0131n de\u011ferini g\u00fcncellemek i\u00e7in k\u00f6\u015feli parantez []<\/code> notasyonu kullan\u0131l\u0131r:<\/p>\n

Bir haritadan eleman okumak i\u00e7in yine k\u00f6\u015feli parantez []<\/code> notasyonu kullan\u0131l\u0131r:<\/p>\n
appleCount := myMap["apple"] \/\/ appleCount 7 olacakt\u0131r\nbananaCount := myMap["banana"] \/\/ bananaCount 10 olacakt\u0131r<\/code><\/pre>\n
Bir anahtar haritada mevcut de\u011filse, okuma i\u015flemi hataya neden olmaz. Bunun yerine, de\u011fer t\u00fcr\u00fcn\u00fcn s\u0131f\u0131r de\u011ferini d\u00f6nd\u00fcr\u00fcr. \u00d6rne\u011fin, string<\/code> anahtarlar\u0131 ve int<\/code> de\u011ferleri olan bir haritada, mevcut olmayan bir anahtar\u0131 okudu\u011funuzda 0<\/code> d\u00f6ner.<\/p>\n
Anahtar\u0131n Mevcudiyetini Kontrol Etme (Comma-ok Idiom)<\/h4>\n
Bir anahtar\u0131n ger\u00e7ekten haritada mevcut olup olmad\u0131\u011f\u0131n\u0131 anlamak i\u00e7in “comma-ok” idiom’u kullan\u0131l\u0131r. Bu idiom, okuma i\u015flemi s\u0131ras\u0131nda ikinci bir boolean de\u011fer d\u00f6nd\u00fcr\u00fcr. Bu de\u011fer, anahtar\u0131n haritada bulunup bulunmad\u0131\u011f\u0131n\u0131 belirtir.<\/p>\n
count, ok := myMap["grape"]\nif ok {\n    fmt.Printf("\u00dcz\u00fcm say\u0131s\u0131: %d\\n", count)\n} else {\n    fmt.Println("\u00dcz\u00fcm bulunamad\u0131.")\n}<\/code><\/pre>\n

Haritalardan Eleman Silme<\/h4>\n
Bir haritadan eleman silmek i\u00e7in delete<\/code> fonksiyonu kullan\u0131l\u0131r:<\/p>\n
delete(myMap, "banana") \/\/ banana eleman\u0131n\u0131 siler<\/code><\/pre>\n

Harita Boyutunu Alma<\/h4>\n
Bir haritadaki eleman say\u0131s\u0131n\u0131 len<\/code> fonksiyonu ile alabilirsiniz:<\/p>\n
mapLength := len(myMap)\nfmt.Printf("Harita boyutu: %d\\n", mapLength)<\/code><\/pre>\n
Harita \u00dczerinde D\u00f6ng\u00fc Yapma (Range)<\/h4>\n

Haritalar\u0131n S\u0131ral\u0131 Olmamas\u0131<\/h4>\n
Daha \u00f6nce de belirtildi\u011fi gibi, Go’daki haritalar do\u011fal olarak s\u0131ral\u0131 de\u011fildir. Elemanlar\u0131n eklenme s\u0131ras\u0131 veya anahtar\u0131n t\u00fcr\u00fc ne olursa olsun, harita \u00fczerinden bir d\u00f6ng\u00fc yap\u0131ld\u0131\u011f\u0131nda elemanlar\u0131n hangi s\u0131rada eri\u015filece\u011fi \u00f6ng\u00f6r\u00fclemez. E\u011fer s\u0131ral\u0131 bir eri\u015fim gerekiyorsa, anahtarlar\u0131 bir dilime (slice) kopyalay\u0131p bu dilimi s\u0131ralayabilir ve ard\u0131ndan bu s\u0131ral\u0131 dilim \u00fczerinden haritaya eri\u015febilirsiniz.<\/p>\n

Haritalar\u0131n E\u015fzamanl\u0131 Kullan\u0131m\u0131 (Concurrency)<\/h4>\n
Go’nun g\u00fc\u00e7l\u00fc e\u015fzamanl\u0131l\u0131k (concurrency) \u00f6zellikleri g\u00f6z \u00f6n\u00fcne al\u0131nd\u0131\u011f\u0131nda, haritalar\u0131n birden fazla goroutine taraf\u0131ndan ayn\u0131 anda eri\u015filmesi ve de\u011fi\u015ftirilmesi \u00f6nemli bir konudur. Go’nun standart haritalar\u0131, e\u015fzamanl\u0131 eri\u015fim i\u00e7in g\u00fcvenli de\u011fildir. Birden fazla goroutine ayn\u0131 anda bir haritay\u0131 okuyor ve yaz\u0131yorsa, veri yar\u0131\u015flar\u0131 (data races) olu\u015fabilir ve bu da \u00f6ng\u00f6r\u00fclemeyen davran\u0131\u015flara veya \u00e7\u00f6kemelere yol a\u00e7abilir.<\/p>\n
Bu sorunu \u00e7\u00f6zmek i\u00e7in Go’nun sync<\/code> paketindeki sync.Map<\/code> kullan\u0131l\u0131r. sync.Map<\/code>, \u00f6zellikle bir\u00e7ok goroutine’in ayn\u0131 harita \u00fczerinde okuma-yazma i\u015flemi yapt\u0131\u011f\u0131 senaryolar i\u00e7in optimize edilmi\u015ftir.<\/p>\n
import "sync"\n\nvar concurrentMap sync.Map\n\nfunc main() {\n    \/\/ Eleman ekleme\n    concurrentMap.Store("key1", 1)\n    concurrentMap.Store("key2", 2)\n\n    \/\/ Eleman okuma\n    if val, ok := concurrentMap.Load("key1"); ok {\n        fmt.Println("key1 de\u011feri:", val)\n    }\n\n    \/\/ Eleman silme\n    concurrentMap.Delete("key2")\n\n    \/\/ T\u00fcm elemanlar \u00fczerinde d\u00f6ng\u00fc\n    concurrentMap.Range(func(key, value interface{}) bool {\n        fmt.Printf("Anahtar: %v, De\u011fer: %v\\n", key, value)\n        return true \/\/ Devam etmek i\u00e7in true d\u00f6nd\u00fcr\u00fcl\u00fcr\n    })\n}<\/code><\/pre>\n
sync.Map<\/code>, standart haritalardan farkl\u0131 bir API’ye sahiptir (Store<\/code>, Load<\/code>, Delete<\/code>, Range<\/code>). Ayr\u0131ca, anahtar ve de\u011fer t\u00fcrleri interface{}<\/code>‘dir, bu da t\u00fcr d\u00f6n\u00fc\u015f\u00fcmleri (type assertions) gerektirebilir. sync.Map<\/code>, standart haritalar kadar performansl\u0131 olmayabilir, ancak e\u015fzamanl\u0131l\u0131k g\u00fcvenli\u011fi gerektiren durumlarda tercih edilmelidir.<\/p>\n
Alternatif olarak, standart haritalar\u0131 kullan\u0131rken, eri\u015fimi senkronize etmek i\u00e7in mutex’ler (mutual exclusion locks) kullanabilirsiniz.<\/p>\n
import (\n    "fmt"\n    "sync"\n)\n\nvar (\n    mu    sync.Mutex\n    myMap = make(map[string]int)\n)\n\nfunc main() {\n    \/\/ Goroutine'ler kullanarak harita \u00fczerine yazma\n    go func() {\n        mu.Lock() \/\/ Kilidi al\n        myMap["a"] = 1\n        mu.Unlock() \/\/ Kilidi b\u0131rak\n    }()\n\n    go func() {\n        mu.Lock()\n        myMap["b"] = 2\n        mu.Unlock()\n    }()\n\n    \/\/ Biraz bekle goroutine'lerin bitmesini sa\u011flamak i\u00e7in\n    time.Sleep(100 * time.Millisecond)\n\n    \/\/ Harita \u00fczerine okuma\n    mu.Lock()\n    fmt.Println(myMap["a"])\n    mu.Unlock()\n}<\/code><\/pre>\n
Bu yakla\u015f\u0131m, sync.Map<\/code>‘e g\u00f6re daha fazla kontrol sa\u011flar ancak daha fazla kod yazmay\u0131 gerektirir. Hangi y\u00f6ntemin kullan\u0131laca\u011f\u0131, uygulaman\u0131n \u00f6zel gereksinimlerine ve performans beklentilerine ba\u011fl\u0131d\u0131r.<\/p>\n
Haritalar\u0131n De\u011fer Olarak Kullan\u0131lmas\u0131<\/h4>\n
Haritalar, di\u011fer Go tipleri gibi de\u011ferler olarak kabul edilir. Bu, bir haritay\u0131 bir fonksiyona arg\u00fcman olarak ge\u00e7irdi\u011finizde veya bir de\u011fi\u015fkene atad\u0131\u011f\u0131n\u0131zda, haritan\u0131n bir kopyas\u0131n\u0131n de\u011fil, orijinal haritan\u0131n bir referans\u0131n\u0131n iletildi\u011fi anlam\u0131na gelir. Bu, fonksiyon i\u00e7inde yap\u0131lan de\u011fi\u015fikliklerin orijinal haritay\u0131 etkileyece\u011fi anlam\u0131na gelir.<\/p>\n

Daha \u00f6nce belirtildi\u011fi gibi, nil<\/code> bir haritaya eleman eklemek bir hataya neden olur. Ancak, nil<\/code> bir haritadan eleman okumak, eleman silmek veya boyutunu almak g\u00fcvenlidir.<\/p>\n
