Class SerializablePairLongStringColumnSerializer

java.lang.Object

org.apache.druid.query.aggregation.SerializablePairLongStringColumnSerializer

All Implemented Interfaces:

GenericColumnSerializer<SerializablePairLongString>, Serializer

public class SerializablePairLongStringColumnSerializer
extends Object
implements GenericColumnSerializer<SerializablePairLongString>

valid call sequence

open()+serialize()*(getSerializedSize()|writeTo())*

getSerializedSize() / writeTo() effectively function as a close call, but each may be called multiple times and has no effect on one another.
