An implementation of this abstract class
can be used to automatically select one or more
Proxy objects to use to connect to a specified
URL. Install an implementation of this class with
the setDefault( )
method. URLConnection implementations use the
installed ProxySelector, if there is one, and call
select( ) to
obtain a list of suitable Proxy objects for the
connection. If a URLConnection cannot contact the
proxy server specified in a Proxy object, it calls
the connectFailed( ) method to notify the
ProxySelector object of the failure.This class is intended to be implemented by advanced users of
java.net and is not for casual use.public abstract class ProxySelector {
// Public Constructors
public ProxySelector ( );
// Public Class Methods
public static ProxySelector getDefault ( );
public static void setDefault (ProxySelector ps );
// Public Instance Methods
public abstract void connectFailed (URI uri , SocketAddress sa ,
java.io.IOException ioe );
public abstract java.util.List<java.net.Proxy> select (URI uri );
