Class IPv4Address

java.lang.Object
  |
  +--com.sun.multicast.allocation.IPv4Address

All Implemented Interfaces:

Address

public class IPv4Address

extends java.lang.Object

implements Address

An IPv4 network address.

Objects of this class and all values returned by their methods are immutable. That is, their values cannot change after they are constructed.

Constructor Summary

IPv4Address(java.net.InetAddress inetAddr)
Creates an AddressRange with the specified addresses.

Method Summary

int	compareTo(java.lang.Object o) Compares this Address with the specified object for order.
long	difference(Address otherAddress) Returns the difference between this Address and another one.
boolean	equals(java.lang.Object obj) Indicates whether some other object is "equal to" this one.
AddressType	getAddressType() Gets the AddressType of this Address.
byte[]	getBytes() Gets a byte array representing this Address.
int	hashCode() Returns a hash code value for this object.
IPv4Address	nextAddress() Returns the next IPv4Address.
IPv4Address	previousAddress() Returns the previous IPv4Address.
java.net.InetAddress	toInetAddress() Returns an InetAddress value for the address.
int	toInt() Returns an int value for the address.
long	toLong() Returns a long value for the address.
java.lang.String	toString() Returns a string representation of this IPv4Address.

Constructor Detail

IPv4Address

public IPv4Address(java.net.InetAddress inetAddr)

Creates an AddressRange with the specified addresses.

Parameters:

startAddress - the first address in the range

endAddress - the last address in the range

Method Detail

compareTo

public int compareTo(java.lang.Object o)
              throws java.lang.ClassCastException

Compares this Address with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

If this address is less than the other one, an integer less than zero is returned. If this address is greater than the other one, an integer greater than zero is returned. If the two addresses are equal, zero is returned. If the two addresses cannot be compared (usually because they are of different AddressTypes), a ClassCastException is thrown.

This method imposes a total ordering on addresses of the same AddressType.

Specified by:

compareTo in interface Address

Parameters:

o - the Object to compare against

Returns:

an integer reflecting the outcome of the comparison

Throws:

java.lang.ClassCastException - if the objects cannot be compared

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one. Two IPv4Addresses are equal if and only if they represent the same address.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object with which to compare

Returns:

true if this object is the same as the reference object, false otherwise.

hashCode

public int hashCode()

Returns a hash code value for this object. The hash code values for two IPv4Addresses are equal if and only if they are equal.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this IPv4Address

toInt

public int toInt()

Returns an int value for the address.

Returns:

an int value for this IPv4Address

toLong

public long toLong()

Returns a long value for the address.

Returns:

a long value for this IPv4Address

toInetAddress

public java.net.InetAddress toInetAddress()

Returns an InetAddress value for the address.

Returns:

an InetAddress value for this IPv4Address

previousAddress

public IPv4Address previousAddress()

Returns the previous IPv4Address.

Returns:

the previous IPv4Address

nextAddress

public IPv4Address nextAddress()

Returns the next IPv4Address.

Returns:

the next IPv4Address

difference

public long difference(Address otherAddress)

Returns the difference between this Address and another one. If this address is less than the other one, a value greater than zero is returned. If this address is greater than the other one, a value less than zero is returned. If the two addresses are equal, zero is returned.

Parameters:

otherAddress - the Address to do a difference with

Returns:

the difference between this Address and the other one

getBytes

public byte[] getBytes()

Gets a byte array representing this Address.

Specified by:

getBytes in interface Address

Returns:

a byte array representing this Address

getAddressType

public AddressType getAddressType()

Gets the AddressType of this Address.

Specified by:

getAddressType in interface Address

Returns:

the AddressType of this Address

toString

public java.lang.String toString()

Returns a string representation of this IPv4Address.

Overrides:

toString in class java.lang.Object

Returns:

a string representation of this IPv4Address
