@InterfaceAudience.Public @InterfaceStability.Stable public class TupleWritable extends TupleWritable
Writables. This is *not* a general-purpose tuple type. In almost all cases, users are encouraged to implement their own serializable types, which can perform better validation and provide more efficient encodings than this class is capable. TupleWritable relies on the join framework for type safety and assumes its instances will rarely be persisted, assumptions not only incompatible with, but contrary to the general case.
|Constructor and Description|
Create an empty tuple with no allocated storage for writables.
Initialize tuple with storage; unknown whether any of them contain "written" values.
