org.apache.hadoop.hive.serde2.lazy.LazyByte

org.apache.hadoop.hive.serde2.lazydio.LazyDioByte

All Implemented Interfaces:

LazyObjectBase

public class LazyDioByte
extends LazyByte

LazyByteBinary for storing a byte value as a ByteWritable. This class complements class LazyByte. It's primary difference is the init(ByteArrayRef, int, int) method, which reads the raw byte value stored.

init

public void init(ByteArrayRef bytes,
                 int start,
                 int length)

Description copied from interface: LazyObjectBase

Set the data for this LazyObjectBase. We take ByteArrayRef instead of byte[] so that we will be able to drop the reference to byte[] by a single assignment. The ByteArrayRef object can be reused across multiple rows.

Specified by:

init in interface LazyObjectBase

Overrides:

init in class LazyByte

Parameters:

bytes - The wrapper of the byte[].

start - The start position inside the bytes.

length - The length of the data, starting from "start"
