  15. def getRandomTimeUUIDFromMicros(whenInMicros: Long): UUID

    Similar to getTimeUUIDFromMicros, but randomize (using SecureRandom) the clock and sequence.

    Similar to getTimeUUIDFromMicros, but randomize (using SecureRandom) the clock and sequence.

    If you can guarantee that the whenInMicros argument is unique (for this JVM instance) for every call, then you should prefer getTimeUUIDFromMicros which is faster. If you can't guarantee this however, this method will ensure the returned UUID are still unique (accross calls) through randomization.

    whenInMicros

    a unix time in microseconds.

    returns

    a new UUID { @code id} such that { @code microsTimestamp(id) == whenInMicros}. The UUID returned by different calls will be unique even if { @code whenInMicros} is not.

  19. def getTimeUUIDBytes(timeMillis: Long, nanos: Int): Array[Byte]

    Converts a 100-nanoseconds precision timestamp into the 16 byte representation of a type 1 UUID (a time-based UUID).

    Converts a 100-nanoseconds precision timestamp into the 16 byte representation of a type 1 UUID (a time-based UUID).

    To specify a 100-nanoseconds precision timestamp, one should provide a milliseconds timestamp and a number 0 <= n < 10000 such that n*100 is the number of nanoseconds within that millisecond.

    Warning: This method is not guaranteed to return unique UUIDs; Multiple invocations using identical timestamps will result in identical UUIDs.

    returns

    a type 1 UUID represented as a byte[]

  20. def getTimeUUIDBytes(timeMillis: Long): Array[Byte]

    Converts a milliseconds-since-epoch timestamp into the 16 byte representation of a type 1 UUID (a time-based UUID).

    Converts a milliseconds-since-epoch timestamp into the 16 byte representation of a type 1 UUID (a time-based UUID).

    Deprecated: This method goes again the principle of a time UUID and should not be used. For queries based on timestamp, minTimeUUID() and maxTimeUUID() can be used but this method has questionable usefulness. This is only kept because CQL2 uses it (see TimeUUID.fromStringCQL2) and we don't want to break compatibility.

    Warning: This method is not guaranteed to return unique UUIDs; Multiple invocations using identical timestamps will result in identical UUIDs.

    returns

    a type 1 UUID represented as a byte[]

  21. def getTimeUUIDFromMicros(whenInMicros: Long): UUID

    Returns a version 1 UUID using the provided timestamp and the local clock and sequence.

    Returns a version 1 UUID using the provided timestamp and the local clock and sequence.

    Note that this method is generally only safe to use if you can guarantee that the provided parameter is unique across calls (otherwise the returned UUID won't be unique accross calls).

    whenInMicros

    a unix time in microseconds.

    returns

    a new UUID { @code id} such that { @code microsTimestamp(id) == whenInMicros}. Please not that multiple calls to this method with the same value of { @code whenInMicros} will return the same UUID.
