org.apache.hadoop.hive.serde2.lazy.LazyBoolean

org.apache.hadoop.hive.serde2.lazydio.LazyDioBoolean

All Implemented Interfaces:

LazyObjectBase

public class LazyDioBoolean
extends LazyBoolean

LazyBooleanBinary for storing a boolean value as an BooleanWritable. This class complements class LazyBoolean. It's primary difference is the init(ByteArrayRef, int, int) method, which reads the boolean 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 LazyBoolean

Parameters:

bytes - The wrapper of the byte[].

start - The start position inside the bytes.

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