Concrete methods
decomposes a uuid into raw bytes.
decomposes a uuid into raw bytes.
Attributes
Returns a milliseconds-since-epoch value for a type-1 UUID.
Returns a milliseconds-since-epoch value for a type-1 UUID.
Attributes
- uuid
a type-1 (time-based) UUID
- Returns:
the number of milliseconds since the unix epoch
- Throws:
- IllegalArgumentException
if the UUID is not version 1
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.
Attributes
- 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.
Creates a type 1 UUID (time-based UUID).
Creates a type 1 UUID (time-based UUID).
Attributes
- Returns:
a UUID instance
Creates a type 1 UUID (time-based UUID) with the timestamp of @param when, in milliseconds.
Creates a type 1 UUID (time-based UUID) with the timestamp of @param when, in milliseconds.
Attributes
- Returns:
a UUID instance
Returns a 16 byte representation of a type 1 UUID (a time-based UUID), based on the current system time.
Returns a 16 byte representation of a type 1 UUID (a time-based UUID), based on the current system time.
Attributes
- Returns:
a type 1 UUID represented as a 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.
Attributes
- Returns:
a type 1 UUID represented as a 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.
Attributes
- Returns:
a type 1 UUID represented as a byte[]
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).
Attributes
- 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.
creates a type 1 uuid from raw bytes.
creates a type 1 uuid from raw bytes.
Attributes
Returns the biggest possible type 1 UUID having the provided timestamp.
Returns the biggest possible type 1 UUID having the provided timestamp.
Warning: this method should only be used for querying as this doesn't at all guarantee the uniqueness of the resulting UUID.
Attributes
Attributes
- Returns:
microseconds since Unix epoch
Returns the smaller possible type 1 UUID having the provided timestamp.
Returns the smaller possible type 1 UUID having the provided timestamp.
Warning: this method should only be used for querying as this doesn't at all guarantee the uniqueness of the resulting UUID.
