All Implemented Interfaces:

Comparable, IAddress

public class IPAddressNetmask
extends IPAddress

This Class represents an IPAddress with Netmask. Convert applies the Netmask to the IPAddress. e.g. IPAddress 192.168.0.1 with Netmask 255.255.255.0. If the Netmask is applied to the Address 192.168.0.0 is returned.

Method Detail

convert

public IPAddress convert()

Applies the Netmask to the IPAddress It calculates bitwise or between Address and Netmask.

Returns:

this address with applied netmask

convert

public IPAddress convert(IPAddress address)

Applies the Netmask to an IPAddress. It calculates bitwise-or between Address and Netmask. e.g. if the ipaddress is 192.168.20.10 and the subnetmask is 255.255.0.0 you will get 192.168.0.0.

Parameters:

address - an address to convert

Returns:

the ipaddress with applied subnetmask (this subnetmask)

equals

public boolean equals(IPAddress address)

Applies the Netmask to this IPAddress and the IPAddress given as parameter and then it compares the two resulting Addresses.

Parameters:

address - an IPAddress to be comapred with this Address.

Returns:

true if this Address applied with this netmask and the Parameter Address with applied netmask are equal.

getNetmask

public IPAddress getNetmask()

this method returns the Nemask.

Returns:

the Netmask
