Class ShortString

java.lang.Object
  net.tomp2p.peers.ShortString

All Implemented Interfaces:

Comparable<ShortString>

public final class ShortString
extends Object
implements Comparable<ShortString>

A short string stores strings with length of up to 19 characters. The length is content by the encoded string using UTF-8. Fill always two variables, the encoded string and the string itself. Although this seems to be a waste of space, the java.lang.string is backed by a char[], thus, if we use this, we might only store string with length 16. These strings (at least in English) will have lots of zeros.
