Class LazyBinaryString

java.lang.Object

org.apache.hadoop.hive.serde2.lazybinary.LazyBinaryObject<OI>

org.apache.hadoop.hive.serde2.lazybinary.LazyBinaryPrimitive<WritableStringObjectInspector,org.apache.hadoop.io.Text>

org.apache.hadoop.hive.serde2.lazybinary.LazyBinaryString

All Implemented Interfaces:

LazyObjectBase

public class LazyBinaryString
extends LazyBinaryPrimitive<WritableStringObjectInspector,org.apache.hadoop.io.Text>

The serialization of LazyBinaryString is very simple: start A end bytes[] -> |---------------------------------| Section A is just an array of bytes which are exactly the Text contained in this object.

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.

Parameters:

bytes - The wrapper of the byte[].

start - The start position inside the bytes.

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