Public methods

equals

Added in API level 9
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

Added in API level 9
InetAddress getAddress ()

Returns an InetAddress for this address.

Returns
InetAddress the InetAddress for this address.

getBroadcast

Added in API level 9
InetAddress getBroadcast ()

Returns an InetAddress for the brodcast 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

Added in API level 9
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

Added in API level 9
int hashCode ()

Returns a hashcode for this Interface address.

Returns
int a hash code value for this Interface address.

toString

Added in API level 9
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.
