An RMIServerSocketFactory instance is used by the RMI runtime
in order to obtain server sockets for RMI calls. A remote object can be
associated with an RMIServerSocketFactory when it is
created/exported via the constructors or exportObject methods
of java.rmi.server.UnicastRemoteObject and
An RMIServerSocketFactory instance associated with a remote
object is used to obtain the ServerSocket used to accept
incoming calls from clients.
An RMIServerSocketFactory instance can also be associated
with a remote object registry so that clients can use custom socket
communication with a remote object registry.
An implementation of this interface
should implement Object.equals(java.lang.Object) to return true when
passed an instance that represents the same (functionally equivalent)
server socket factory, and false otherwise (and it should also
implement Object.hashCode() consistently with its
