Class HiveColumnHandle

java.lang.Object
io.trino.plugin.hive.HiveColumnHandle
All Implemented Interfaces:
ColumnHandle
public class HiveColumnHandle extends Object implements ColumnHandle
ColumnHandle for Hive Connector representing a full top level column or a projected column. Currently projected columns that represent a simple chain of dereferences are supported. e.g. for a column "A" with type struct(B struct(C bigint, ...), ....) there can be a projected column representing expression "A.B.C".
