Java 1.2

This interface defines constants that represent low-level BSD Unix-style socket options and methods that set and query the value of those options. In Java 1.2, SocketImpl and DatagramSocketImpl implement this interface. Any custom socket implementations you define should also provide meaningful implementations for the getOption( ) and setOption( ) methods. Your implementation may support options other than those defined here. Only custom socket implementations need to use this interface. All other code can use methods defined by Socket , ServerSocket , DatagramSocket , and MulticastSocket to set specific socket options for those socket types.
