Enum Class DeserializationHelper.Flag

java.lang.Object
java.lang.Enum<DeserializationHelper.Flag>
org.apache.cassandra.db.rows.DeserializationHelper.Flag
All Implemented Interfaces:
Serializable, Comparable<DeserializationHelper.Flag>, Constable
Enclosing class:
DeserializationHelper
public static enum DeserializationHelper.Flag extends Enum<DeserializationHelper.Flag>
Flag affecting deserialization behavior (this only affect counters in practice). - LOCAL: for deserialization of local data (Expired columns are converted to tombstones (to gain disk space)). - FROM_REMOTE: for deserialization of data received from remote hosts (Expired columns are converted to tombstone and counters have their delta cleared) - PRESERVE_SIZE: used when no transformation must be performed, i.e, when we must ensure that deserializing and reserializing the result yield the exact same bytes. Streaming uses this.
