public
final
enum
OptionUpdateRule
extends Enum<OptionUpdateRule>

atau ERROR(/Map)
.
Ringkasan
Nilai enum
FIRST
public static final OptionUpdateRule FIRST
Setelah opsi ditetapkan, upaya berikutnya untuk memperbaruinya akan diabaikan.
TERBESAR
public static final OptionUpdateRule GREATEST
untuk opsi Comparable
, pertahankan opsi yang dibandingkan sebagai yang terbesar.
TERAKHIR
public static final OptionUpdateRule LAST
jika opsi ditetapkan beberapa kali, abaikan semua kecuali nilai terakhir.
Metode publik
shouldUpdate
public boolean shouldUpdate (String optionName,
Object optionSource,
Field field,
Object update)
Mengambil nilai saat ini dan nilai pembaruan, serta menampilkan apakah nilai harus
diperbarui. Mengasumsikan bahwa update
tidak pernah null.
