ColumnVector

java.lang.Object
- org.apache.iceberg.arrow.vectorized.ColumnVector

All Implemented Interfaces:

java.lang.AutoCloseable
```
public class ColumnVector
extends java.lang.Object
implements java.lang.AutoCloseable
```
This class is inspired by Spark's ColumnVector. This class represents the column data for an Iceberg table query. It wraps an arrow FieldVector and provides simple accessors for the row values. Advanced users can access the FieldVector.
Supported Iceberg data types:
- Types.BooleanType
- Types.IntegerType
- Types.LongType
- Types.FloatType
- Types.DoubleType
- Types.StringType
- Types.BinaryType
- Types.TimestampType (with and without timezone)
- Types.DateType
- Types.TimeType
- Types.UUIDType
