Class ColumnIdMap

java.lang.Object

org.apache.iceberg.orc.ColumnIdMap

All Implemented Interfaces:

java.util.Map<org.apache.orc.TypeDescription,java.lang.Integer>

public class ColumnIdMap
extends java.lang.Object
implements java.util.Map<org.apache.orc.TypeDescription,java.lang.Integer>

The mapping from ORC's TypeDescription to the Iceberg column ids.

Keep the API limited to Map rather than a concrete type so that we can change it later.
