Public methods
equals
public boolean equals (Object obj)
Compares this object against the specified object.
The result is true
if and only if the argument is
not null
and it represents the same interface address as
this object.
Two instances of InterfaceAddress
represent the same
address if the InetAddress, the prefix length and the broadcast are
the same for both.
Parameters | |
---|---|
obj |
Object : the object to compare against. |
Returns | |
---|---|
boolean |
true if the objects are the same;
false otherwise. |

getAddress
public InetAddress getAddress ()
Returns an InetAddress
for this address.
Returns | |
---|---|
InetAddress |
the InetAddress for this address. |
getBroadcast
public InetAddress getBroadcast ()
Returns an InetAddress
for the broadcast address
for this InterfaceAddress.
Only IPv4 networks have broadcast address therefore, in the case
of an IPv6 network, null
will be returned.
Returns | |
---|---|
InetAddress |
the InetAddress representing the broadcast
address or null if there is no broadcast address. |
getNetworkPrefixLength
public short getNetworkPrefixLength ()
Returns the network prefix length for this address. This is also known as the subnet mask in the context of IPv4 addresses. Typical IPv4 values would be 8 (255.0.0.0), 16 (255.255.0.0) or 24 (255.255.255.0).
Typical IPv6 values would be 128 (::1/128) or 10 (fe80::203:baff:fe27:1243/10)
Returns | |
---|---|
short |
a short representing the prefix length for the
subnet of that address. |
hashCode
public int hashCode ()
Returns a hashcode for this Interface address.
Returns | |
---|---|
int |
a hash code value for this Interface address. |
toString
public String toString ()
Converts this Interface address to a String
. The
string returned is of the form: InetAddress / prefix length [ broadcast address ].
Returns | |
---|---|
String |
a string representation of this Interface address. |
