ProxySelector

ProxySelector

java.net

---

Java 5.0

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.
