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.
