SORU
22 HAZİRAN 2012, Cuma


Liste görünümü getListİtemXmlAttributes yöntem çocuk yayın öğeleri ile başarısız oluyor.

JS bir sınıf öğeler değiştirildiğinde SG/Klasör liste görünümünde verileri doldurmak için oluşturduk. (As per Jaime's approach) Her şeyi ortaya çıkarlar yayında kalemleri ameliyat ederken harika çalışıyor.

Ex:Bir bileşen veya sayfa ve locked by sütun hemen ve benim kullanıcı adı güncellemeleri gösterir özel açıyorum.

Çocuk bir yayın ve bu işlemi tekrarlayın gittiğimde ancak eğer veya üst öğe yerleştirmek düzenlemek istiyorum eğer pencere soruyorum. Eğer üst pencere düzenlemek için seçerseniz, kod çalışmıyor. Henüz ilk hata ayıklama ile çözemedim. Chrome hata yutmak gibi görünüyor, Firefox bana bir şifreli verir:

Zaman damgası: 6/22/2012 3:42:54

Hata: yakalanmamış özel durum: [..."Bileşen döndürülen hata kodu: 0x80004002 Durum (NS_NOİNTERFACE) [nsİWebProgress.DOMWindow]" nsresult: "0x80004002 (NS_NOİNTERFACE)" konum: "JS çerçeve :: chrome://browser/content/tabbrowser.xml :: :: çizgi 545" veri: hayır]

Güzel soru. Aşağıdaki varbeş6 bunu yapmak için yöntem.

1. String stringValueOf = String.valueOf('c'); // most efficient

2. String stringValueOfCharArray = String.valueOf(new char[]{x});

3. String characterToString = Character.toString('c');

4. String characterObjectToString = new Character('c').toString();

   // Although this method seems very simple, 
   // this is less efficient because the concatenation
   // expands to new StringBuilder().append(x).append("").toString();
5. String concatBlankString = 'c'   "";

6. String fromCharArray = new String(new char[]{x});

Not: Character.toString(char) döner String.valueOf(char). Çok etkili ikisi de aynı.

String.valueOf(char[] value) value char dizi ayarlar new String(char[] value) çağırır.

public String(char value[]) {
    this.value = Arrays.copyOf(value, value.length);
}

Diğer yandan String.valueOf(char value) aşağıdaki paket özel kurucusunu çağırır.

String(char[] value, boolean share) {
    // assert share : "unshared not supported";
    this.value = value;
}

Java 8 source code 15 *baktıktan sonra

String.valueOf(char) String char dönüştürmek için en etkili yöntem gibi görünüyor.
