Package java.net
Class InterfaceAddress
java.lang.Object
java.net.InterfaceAddress
public class InterfaceAddress extends Object
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.

- 1.6

Method Summary
Modifier and Type Method Description booleanequals(Object obj)Tests whether this object is equal to another one.InetAddressgetAddress()Returns the InetAddress for this address.InetAddressgetBroadcast()Returns the subnet-directed broadcast address if this is an IPv4 interface, null otherwise.shortgetNetworkPrefixLength()Returns the network prefix length in bits.inthashCode()Returns an integer hash code for this object.StringtoString()Returns a string containing this interface's address, prefix length, and broadcast address.

Method Details
-
equals
Tests whether this object is equal to another one. Returns true if the address, broadcast address and prefix length are all equal.- Overrides:
equalsin classObject- Parameters:
obj- the object to be compared.- Returns:
- true if 'obj' is equal to this InterfaceAddress, false otherwise.
- See Also:
Object.hashCode()
-
hashCode
public int hashCode()Description copied from class:ObjectReturns an integer hash code for this object. By contract, any two objects for whichObject.equals(java.lang.Object)returnstruemust return the same hash code value. This means that subclasses ofObjectusually 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
hashCodemethod if you intend implementing your ownhashCodemethod.- Overrides:
hashCodein classObject- Returns:
- this object's hash code.
- See Also:
Object.equals(java.lang.Object)
-
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]". -
getAddress
Returns the InetAddress for this address. -
getBroadcast
Returns the subnet-directed broadcast address if this is an IPv4 interface, null otherwise. -
getNetworkPrefixLength
public 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.)
