Field Detail

bitsInMask

Constructor Detail

IpNetmask

public IpNetmask(java.lang.String netmask)

---

IpNetmask

public IpNetmask(int bitsInMask)

Method Detail

parseBitCount

public static byte[] parseBitCount(int bits)

Converts into a long for a IP V4 netmask. Throws an exception if bit count is greater than 32. This is only a V4 convention.

---

getBitsInNetmask

public int getBitsInNetmask()

Return the number of bits turn on in a netmask. This is use full if you want to display the netmask as a slash with number of bits in mask.

---

applyNetmask

public byte[] applyNetmask(Address ip)

This method applies the netmask to another IpNumber object such as IpAddress or IpNetwork. Netmask is ANDed with every byte in the corresponding object. If number of bytes in the netmask does not match the number in the IpNumber object then an IllegalArgumentException is thrown.

---

applyNetmask

public byte[] applyNetmask(byte[] ip)

---

countBits

private static int countBits(byte[] byteArray)

---

toString

public java.lang.String toString()

Description copied from class: Address

Convert to dot notation string representation of the address

Overrides:

toString in class Address

---

main

public static void main(java.lang.String[] args)

Test function for IpNetmask
