Class InetNetworkBuilder

java.lang.Object
  org.apache.james.util.inetnetwork.InetNetworkBuilder

public class InetNetworkBuilder
extends java.lang.Object

Builds a InetNetwork (Inet4Network or Inet6Network) in function on the provided string pattern that represents a subnet. Inet4Network is constructed based on the IPv4 subnet expressed in one of several formats: IPv4 Format Example Explicit address 127.0.0.1 Address with a wildcard 127.0.0.* Domain name myHost.com Domain name + prefix-length myHost.com/24 Domain name + mask myHost.com/255.255.255.0 IP address + prefix-length 127.0.0.0/8 IP + mask 127.0.0.0/255.0.0.0 For more information on IP V4, see RFC 1518 and RFC 1519. Inet6Network is constructed based on the IPv4 subnet expressed in one of several formats: IPv6 Format Example Explicit address 0000:0000:0000:0000:0000:0000:0000:0001 IP address + subnet mask (/) 0000:0000:0000:0000:0000:0000:0000:0001/64 IP address + subnet mask (%) 0000:0000:0000:0000:0000:0000:0000:0001%64 The following V6 formats will be supported later: Domain name myHost.com Domain name + mask (/) myHost.com/48 Domain name + mask (%) myHost.com%48 Explicit shorted address ::1 For more information on IP V6, see RFC 2460.

Method Detail

getFromString

public InetNetwork getFromString(java.lang.String netspec)
                          throws java.net.UnknownHostException

Creates a InetNetwork for the given String. Depending on the provided pattern and the platform configuration (IPv4 and/or IPv6), the returned type will be Inet4Network or Inet6Network.

Parameters:

netspec - the String which is will converted to InetNetwork

Returns:

network the InetNetwork
