 * Interface of methods to get/set socket options.  This interface is
 * implemented by: <B>SocketImpl</B> and  <B>DatagramSocketImpl</B>.  
 * Subclasses of these should override the methods
 * of this interface in order to support their own options.
 * <P>
 * The methods and constants which specify options in this interface are
 * for implementation only.  If you're not subclassing SocketImpl or
 * DatagramSocketImpl, <B>you won't use these directly.</B> There are
 * type-safe methods to get/set each of these options in Socket, ServerSocket, 
 * DatagramSocket and MulticastSocket.
 * <P>
 * A subset of the standard BSD-style socket options are supported in the
 * JDK base classes, <B>PlainSocketImpl</B> and <B>PlainDatagramSocketImpl</B>.  
 * A brief description of each and their use is provided.
