Class ZipShort

public final class ZipShort extends Object implements Cloneable

Utility class that represents a two byte integer with conversion rules for the big endian byte order of ZIP files.

Constructor Summary
	ZipShort(int value) Create instance from a number.
	ZipShort(byte[] bytes) Create instance from bytes.
	ZipShort(byte[] bytes, int offset) Create instance from the two bytes starting at offset.

Method Summary
boolean	equals(Object o) Override to make two instances with same value equal.
byte[]	getBytes() Get value as two bytes in big endian byte order.
static byte[]	getBytes(int value) Get value as two bytes in big endian byte order.
int	getValue() Get value as Java int.
static int	getValue(byte[] bytes, int offset) Helper method to get the value as a java int from two bytes starting at given array offset
static int	getValue(byte[] bytes) Helper method to get the value as a java int from a two-byte array
int	hashCode() Override to make two instances with same value equal.
