public interface LazyObjectBase

Method Summary

Modifier and Type	Method and Description
Object	getObject() If the LazyObjectBase is a primitive Object, then deserialize it and return the actual primitive Object.
void	init(ByteArrayRef bytes, int start, int length) Set the data for this LazyObjectBase.
void	setNull() called for null binary, hbase columns, for example

Method Detail

init

void init(ByteArrayRef bytes,
          int start,
          int length)

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"

setNull

void setNull()

called for null binary, hbase columns, for example

getObject

Object getObject()

If the LazyObjectBase is a primitive Object, then deserialize it and return the actual primitive Object. Otherwise (array, map, struct), return this.
