Enum Values
AUTOMATIC
RoomDatabase.JournalMode RoomDatabase.JournalMode.AUTOMATIC
Let Room choose the journal mode. This is the default value when no explicit value is specified.
The actual value will be TRUNCATE when the device runs API Level lower than 16 or it is a low-RAM device. Otherwise, WRITE_AHEAD_LOGGING will be used.
WRITE_AHEAD_LOGGING
RoomDatabase.JournalMode RoomDatabase.JournalMode.WRITE_AHEAD_LOGGING
Write-Ahead Logging mode.
Public methods
getEntries
public final @NonNull EnumEntries<@NonNull RoomDatabase.JournalMode> getEntries()
Returns an immutable kotlin.enums.EnumEntries list containing the constants of this enum type, in the order they're declared.
getEntries
public final @NonNull EnumEntries<@NonNull RoomDatabase.JournalMode> getEntries()
Returns an immutable kotlin.enums.EnumEntries list containing the constants of this enum type, in the order they're declared.
getEntries
public final @NonNull EnumEntries<@NonNull RoomDatabase.JournalMode> getEntries()
Returns an immutable kotlin.enums.EnumEntries list containing the constants of this enum type, in the order they're declared.
valueOf
public static final @NonNull RoomDatabase.JournalMode valueOf(@NonNull String value)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
| Throws | |
|---|---|
kotlin.IllegalArgumentException |
if this enum type has no constant with the specified name |
valueOf
public static final @NonNull RoomDatabase.JournalMode valueOf(@NonNull String value)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
| Throws | |
|---|---|
kotlin.IllegalArgumentException |
if this enum type has no constant with the specified name |
valueOf
public static final @NonNull RoomDatabase.JournalMode valueOf(@NonNull String value)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
| Throws | |
|---|---|
kotlin.IllegalArgumentException |
if this enum type has no constant with the specified name |
values
public static final @NonNull RoomDatabase.JournalMode[] values()
Returns an array containing the constants of this enum type, in the order they're declared.
This method may be used to iterate over the constants.
The function returns a new instance of the array on every call. The array could be mutated, so working with it may also require defensive copying. Consider using entries property as a more efficient alternative returning an immutable list of enum entries.
