Class InstantCodec

java.lang.Object

com.datastax.driver.core.TypeCodec<Instant>

com.datastax.driver.extras.codecs.jdk8.InstantCodec

public class InstantCodec
extends com.datastax.driver.core.TypeCodec<Instant>

TypeCodec that maps Instant to CQL timestamp allowing the setting and retrieval of timestamp columns as Instant instances.

Since C* timestamp columns do not preserve timezones any attached timezone information will be lost.

IMPORTANT: this codec's format method formats timestamps using an ISO-8601 format that includes milliseconds. This format is incompatible with Cassandra versions < 2.0.9.
