## org.apache.tools.zip
Class ZipLong

    java.lang.Object
      org.apache.tools.zip.ZipLong

All Implemented Interfaces:
  java.lang.Cloneable

    public final class ZipLong

extends java.lang.Object
implements java.lang.Cloneable

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

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

Method Summary
`boolean` | `equals(java.lang.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)` Helper method to get the value as a Java long from a four-byte array
`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
`int` | `hashCode()` Override to make two instances with same value equal.
