Field Details

OS_DETERMINED

public static DiskDurability OS_DETERMINED

Static instance of DiskDurability representing disk durability that is left to the operating system. This is the laxest durability, and delegates disk flushing to operating system. Note that this is a constraint, and the implementation is free to be more conservative.

ALWAYS

public static DiskDurability ALWAYS

Static instance of DiskDurability representing disk durability where every mutative operation is fully synced/fsynched/flushed to disk. Note that this is a constraint, and the implementation is free to be more conservative.

Method Details

timed

public static BaseDiskDurability.Timed timed(Long duration,
 TimeUnit units)

Static factory for timed DiskDurability instances. The time duration denotes the longest time a mutative change will go without being fully synced/fsynched/flushed to disk. Note that this is a constraint, and the implementation is free to be more conservative.

Parameters:

duration - long duration

units - units of the duration

Returns:

timed disk durability

getDurabilityEnum

public DiskDurability.DiskDurabilityEnum getDurabilityEnum()

Specified by:

getDurabilityEnum in interface DiskDurability

toString

public String toString()

Overrides:

toString in class Object

mergeConservatively

public DiskDurability mergeConservatively(DiskDurability other)

Specified by:

mergeConservatively in interface DiskDurability
