Class UVLongTool

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

@InterfaceAudience.Private
public class UVLongTool
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	LONG_7_RIGHT_BITS_SET
static long	LONG_8TH_BIT_SET
static byte[]	MAX_VALUE_BYTES

Constructor Summary

UVLongTool()

Method Summary

static byte[]	getBytes(long value)
static long	getLong(byte[] bytes) bytes -> long
static long	getLong(byte[] bytes, int offset)
static long	getLong(InputStream is)
