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.
