Class CastedArray

java.lang.Object

org.apache.paimon.casting.CastedArray

All Implemented Interfaces:

DataGetters, InternalArray

public class CastedArray
extends Object
implements InternalArray

An implementation of InternalArray which provides a casted view of the underlying InternalArray.

It reads data from underlying InternalArray according to source logical type and casts it with specific CastExecutor.

Method Detail

from

public static CastedArray from(CastElementGetter castElementGetter)

Replaces the underlying InternalArray backing this CastedArray.

This method replaces the array in place and does not return a new object. This is done for performance reasons.
