Enum Timestamps

java.lang.Object

java.lang.Enum<Timestamps>

com.thinkaurelius.titan.diskstorage.util.time.Timestamps

All Implemented Interfaces:

TimestampProvider, Serializable, Comparable<Timestamps>

public enum Timestamps
extends Enum<Timestamps>
implements TimestampProvider

Implementations of TimestampProvider for different resolutions of time:

• NANO: nano-second time resolution based on System.nanoTime using a base-time established by System.currentTimeMillis(). The exact resolution depends on the particular JVM and host machine.
• MICRO: micro-second time which is actually at milli-second resolution.
• MILLI: milli-second time resolution

Method Detail

values

public static Timestamps[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Timestamps c : Timestamps.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Timestamps valueOf(String name)

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.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

sleepPast

public Timepoint sleepPast(Timepoint futureTime)
                    throws InterruptedException

Description copied from interface: TimestampProvider

Block until the current time as returned by TimestampProvider.getTime() is greater than the given timepoint.

Specified by:

sleepPast in interface TimestampProvider

Parameters:

futureTime - The time to sleep past

Returns:

the current time in the same units as the unit argument

Throws:

InterruptedException - if externally interrupted

sleepFor

public void sleepFor(Duration duration)
              throws InterruptedException

Description copied from interface: TimestampProvider

Sleep for the given duration of time.

Specified by:

sleepFor in interface TimestampProvider

Throws:

InterruptedException

getTimer

public Timer getTimer()

Description copied from interface: TimestampProvider

Returns a Timer based on this timestamp provider

Specified by:

getTimer in interface TimestampProvider

Returns:

toString

public String toString()

Overrides:

toString in class Enum<Timestamps>

getTime

public Timepoint getTime(long sinceEpoch,
                TimeUnit unit)

Description copied from interface: TimestampProvider

Returns the given time as a Timepoint based off of this timestamp provider

Specified by:

getTime in interface TimestampProvider

Returns:
