 java.net.ProxySelector
All known Subclasses: java.net.ProxySelectorImpl,
| ProxySelector | | abstract public class ProxySelector (Code) | |
Selects applicable proxies when connecting to network resouce represented by
a URI. An implementation of ProxySelector
should be a concrete subclass of ProxySelector. Method
select returns a list of proxies according to the
uri. If a connection can't be established, the caller should
notify proxy selector by invoking connectFailed method.
A proxy selector can be registered/unregistered by calling
setDefault method and retrieved by calling
getDefault method.

| ProxySelector | | public ProxySelector()(Code) | | Constructor method.
|
| connectFailed | | abstract public void connectFailed(URI uri, SocketAddress sa, IOException ioe)(Code) | | If the connection can not be established to the proxy server, this method
will be called. An implementation may adjust proxy the sequence of
proxies returned by select(String, String).
Parameters:
uri - the URI that the connection fails to connectto.
Parameters:
sa - SocketAddress of the proxy.
Parameters:
ioe - The IOException which is thrown duringconnection establishment.
throws:
IllegalArgumentException - If any argument is null. |
| getDefault | | public static ProxySelector getDefault()(Code) | | Gets system default ProxySelector.
system default ProxySelector.
throws:
SecurtiyException - If a security manager is installed and it doesn't haveNetPermission("getProxySelector"). |
| select | | abstract public List<Proxy> select(URI uri)(Code) | | Gets applicable proxies based on the accessing protocol of
uri. The format of URI is defined as below:
http URI stands for http connection.
https URI stands for https connection.
ftp URI stands for ftp connection.
socket:://ip:port URI stands for tcp client sockets connection.
Parameters:
uri - the destination URI object. a list contains all applicable proxies. If no proxy is available,returns a list only contains one elementProxy.NO_PROXY.
throws:

| setDefault | | public static void setDefault(ProxySelector selector)(Code) | | Sets system default ProxySelector. Unsets system default
