public class LazyDioLong
extends LazyLong

LazyLongBinary for storing a long value as a LongWritable. This class complements class LazyLong. It's primary difference is the init(ByteArrayRef, int, int) method, which reads the long value stored in the default binary format.

Description copied from class: 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.

Overrides:

init in class LazyLong

Parameters:

bytes - The wrapper of the byte[].

start - The start position inside the bytes.

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