Class ZipLong

public final class ZipLong extends Object implements Cloneable

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

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

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

Constructor Detail

ZipLong

public ZipLong(long value)
