java.lang.Object

com.datastax.driver.core.ServerSideTimestampGenerator

All Implemented Interfaces:

TimestampGenerator

public class ServerSideTimestampGenerator
extends Object
implements TimestampGenerator

A timestamp generator that always returns Long.MIN_VALUE, in order to let Cassandra assign server-side timestamps.

Method Detail

next

public long next()

Description copied from interface: TimestampGenerator

Returns the next timestamp.

Implementors should enforce increasing monotonicity of timestamps, that is, a timestamp returned should always be strictly greater that any previously returned timestamp.

Implementors should strive to achieve microsecond precision in the best possible way, which is usually largely dependent on the underlying operating system's capabilities.

Specified by:

next in interface TimestampGenerator

Returns:

the next timestamp (in microseconds). If it equals Long.MIN_VALUE, it won't be sent by the driver, letting Cassandra generate a server-side timestamp.
