javatools.datatypes.ByteString

All Implemented Interfaces:

public class ByteString
extends java.lang.Object
implements java.lang.CharSequence

It is licensed under the Creative Commons Attribution License (see http://creativecommons.org/licenses/by/3.0) by the YAGO-NAGA team (see http://mpii.de/yago-naga). This class represents strings with 1 byte per character. Thus, they use roughly half as much space as ordinary strings -- but they also cannot store all characters. ByteStrings are always unique. they can be compared with ==.
