InterfaceAddress

public class InterfaceAddress
extends Object

java.lang.Object
   ↳ java.net.InterfaceAddress


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.

Inherited methods

From class java.lang.Object

Public methods

equals

Added in API level 9
boolean equals (Object obj)

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

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

getAddress

Added in API level 9
InetAddress getAddress ()

Returns the InetAddress for this address.

Returns
InetAddress

getBroadcast

Added in API level 9
InetAddress getBroadcast ()

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

Returns
InetAddress

getNetworkPrefixLength

Added in API level 9
short getNetworkPrefixLength ()

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.)

Returns
short

hashCode

Added in API level 9
int hashCode ()

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
int this object's hash code.

toString

Added in API level 9
String toString ()

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
String a printable representation of this object.
