public class LazyBinaryBoolean
extends LazyBinaryPrimitive<WritableBooleanObjectInspector,org.apache.hadoop.io.BooleanWritable>

LazyBinaryObject for boolean which takes one byte

Part of the code is adapted from Apache Harmony Project. As with the specification, this implementation relied on code laid out in Henry S. Warren, Jr.'s Hacker's Delight, (Addison Wesley, 2002) as well as The Aggregate's Magic Algorithms.

public void init(ByteArrayRef bytes,

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.

Specified by:

init in class LazyObjectBase

Parameters:

bytes - The wrapper of the byte[].

start - The start position inside the bytes.

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