java.lang.Object

org.zeroturnaround.zip.extra.ZipShort

All Implemented Interfaces:

Cloneable

public final class ZipShort
extends Object
implements Cloneable

This is a class that has been made significantly smaller (deleted a bunch of methods) and originally is from the Apache Ant Project (http://ant.apache.org), org.apache.tools.zip package. All license and other documentation is intact. Utility class that represents a two byte integer with conversion rules for the big endian byte order of ZIP files.
