Class UVIntTool

java.lang.Object
  org.apache.hadoop.hbase.util.vint.UVIntTool

@InterfaceAudience.Private
public class UVIntTool
extends Object

Simple Variable Length Integer encoding. Left bit of 0 means we are on the last byte. If left bit of the current byte is 1, then there is at least one more byte.

Field Summary

static byte	BYTE_7_RIGHT_BITS_SET
static byte	BYTE_LEFT_BIT_SET
static long	INT_7_RIGHT_BITS_SET
static long	INT_8TH_BIT_SET
static byte[]	MAX_VALUE_BYTES

Constructor Summary

UVIntTool()

Method Summary

static byte[]	getBytes(int value)
static int	getInt(byte[] bytes) bytes -> int
static int	getInt(byte[] bytes, int offset)
