public static File translatePath(String root,
                                 String url)
                          throws UnsupportedEncodingException

isSecure

public static boolean isSecure(String root,
                               File file)
                        throws IOException

findRoutableHostAddress

public static InetAddress findRoutableHostAddress()
                                           throws UnknownHostException,
                                                  SocketException

This method tries to find a suitable InetAddress that is routable. It calls InetAddress.getLocalHost() to find the local host. If that address it a site local address (192.168.*.*, 10.*.*.*, or 172.16.*.*) or the loopback address (127.0.0.1), it enumerates all the NetworkInterfaces, and tries to find an address that is not site local or loopback address. If it cannot it simply returns whatever InetAddress.getLocalHost().

返回:

the address of a non site local or non loopback address, unless there is only loopback or site local addresses.

抛出:

UnknownHostException

SocketException

findAllHostAddresses

public static List findAllHostAddresses(boolean includeLoopback)
                                 throws SocketException

抛出:

SocketException
