org.apache.hadoop.hive.serde2.lazy.LazyInteger

org.apache.hadoop.hive.serde2.lazydio.LazyDioInteger

All Implemented Interfaces:

LazyObjectBase

public class LazyDioInteger
extends LazyInteger

LazyIntegerBinary for storing an int value as an IntWritable. This class complements class LazyInteger. It's primary difference is the init(ByteArrayRef, int, int) method, which reads the integer value stored from the default binary format.

Method Detail

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 LazyInteger

Parameters:

bytes - The wrapper of the byte[].

start - The start position inside the bytes.

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