Class Int

java.lang.Object
  com.lukasfeiler.util.Int

Direct Known Subclasses:

IPAddress, Netmask

public class Int

extends java.lang.Object

A 32 Bit Integer. This class allows a bitwise handling of an integer. The integer can be as well separated into 4 octets. This class is also capable of handling the dotted-quad notation (as used for IPv4 addresses).

Constructor Summary

Int(int i)
Constructor that takes an int value as an argument.

Int(java.lang.String s)
Constructor that takes the integer in dottet-quad notation as an argument.

Method Summary

boolean	allBitsSet() Returns whether all bits are set.
boolean	getBit(int bitNumber) Returns one of the 32 bits as a boolean value.
short	getOctet(int octetNumber) Returns one of the 4 octets as a short value.
short[]	getOctets() Returns the 4 octets of the 32 bit integer as a short array.
int	intValue() Returns the int value of this instance.
java.lang.String	toBitString() Returns all the bits of this integer as a string (e.g. 11000000101010000000000100001010 for -1062731510).
java.lang.String	toString() Returns the integer in the dottet-quad notation (e.g. 192.168.1.10).
