InterfaceAddress

extends Object
java.lang.Object
   ↳ java.net.InterfaceAddress

Class Overview

Identifies one of a network interface's addresses. These are passed back from the JNI behind NetworkInterface.getNetworkInterfaces. Multiple addresses for the same interface are collected together on the Java side.

Summary

Public Methods
boolean equals(Object obj)
Tests whether this object is equal to another one.
InetAddress getAddress()
Returns the InetAddress for this address.
InetAddress getBroadcast()
Returns the subnet-directed broadcast address if this is an IPv4 interface, null otherwise.
short getNetworkPrefixLength()
Returns the network prefix length in bits.
int hashCode()
Returns an integer hash code for this object.
String toString()
Returns a string containing this interface's address, prefix length, and broadcast address.

Public Methods

public boolean equals (Object obj)

Since: API Level 9

Tests whether this object is equal to another one. Returns true if the address, broadcast address and prefix length are all equal.

Parameters
obj the object to be compared.
Returns
  • true if 'obj' is equal to this InterfaceAddress, false otherwise.

public InetAddress getAddress ()

Since: API Level 9

Returns the InetAddress for this address.

public InetAddress getBroadcast ()

Since: API Level 9

Returns the subnet-directed broadcast address if this is an IPv4 interface, null otherwise.

public short getNetworkPrefixLength ()

Since: API Level 9

Returns the network prefix length in bits. (In IPv4 parlance, this is known as the subnet mask, but this method applies to IPv6 addresses too.)

public int hashCode ()

Since: API Level 9

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
  • this object's hash code.

public String toString ()

Since: API Level 9

Returns a string containing this interface's address, prefix length, and broadcast address. For example: "/172.18.103.112/23 [/172.18.103.255]" or "/0:0:0:0:0:0:0:1%1/128 [null]".

Returns
  • a printable representation of this object.
