Note: This is not a public class, so that applets cannot call into the implementation directly and hence cannot bypass the security checks present in the DatagramSocket and MulticastSocket classes. author:    Pavani Diwanji Method Summary native protected synchronized  void bind(int lport, InetAddress laddr)      Binds a datagram socket to a local port. protected  void close()      Close the socket. protected  void connect(InetAddress address, int port)      Connects a datagram socket to a remote destination. protected synchronized  void create()      protected  void disconnect()      Disconnects a previously connected socket. protected  void finalize()      public  Object getOption(int optID)      native protected  int getTimeToLive()      Get the TTL (time-to-live) option. protected  void join(InetAddress inetaddr)      Join the multicast group. protected  void joinGroup(SocketAddress mcastaddr, NetworkInterface netIf)      Join the multicast group. protected  void leave(InetAddress inetaddr)      Leave the multicast group. protected  void leaveGroup(SocketAddress mcastaddr, NetworkInterface netIf)      Leave the multicast group. native protected synchronized  int peek(InetAddress i)      Peek at the packet to see who it is from. native protected synchronized  int peekData(DatagramPacket p)      native protected synchronized  void receive(DatagramPacket p)      Receive the datagram packet. native protected  void send(DatagramPacket p)      Sends a datagram packet. public  void setOption(int optID, Object o)      native protected  void setTimeToLive(int ttl)      Set the TTL (time-to-live) option. Method Detail bind native protected synchronized void bind(int lport, InetAddress laddr) throws SocketException(Code) Binds a datagram socket to a local port. close protected void close()(Code) Close the socket. connect protected void connect(InetAddress address, int port) throws SocketException(Code) Connects a datagram socket to a remote destination. This associates the remote address with the local socket so that datagrams may only be sent to this destination and received from this destination. Parameters:   address - the remote InetAddress to connect to Parameters:   port - the remote port number create protected synchronized void create() throws SocketException(Code) Creates a datagram socket disconnect protected void disconnect()(Code) Disconnects a previously connected socket. Does nothing if the socket was not connected already. finalize protected void finalize()(Code) getOption public Object getOption(int optID) throws SocketException(Code) getTimeToLive native protected int getTimeToLive() throws IOException(Code) Get the TTL (time-to-live) option. join protected void join(InetAddress inetaddr) throws IOException(Code) Join the multicast group. Parameters:   multicast - address to join. joinGroup protected void joinGroup(SocketAddress mcastaddr, NetworkInterface netIf) throws IOException(Code) Join the multicast group. Parameters:   multicast - address to join. Parameters:   netIf - specifies the local interface to receive multicastdatagram packets throws:   IllegalArgumentException - if mcastaddr is null or is aSocketAddress subclass not supported by this socket since:    1.4 leave protected void leave(InetAddress inetaddr) throws IOException(Code) Leave the multicast group. Parameters:   multicast - address to leave. leaveGroup protected void leaveGroup(SocketAddress mcastaddr, NetworkInterface netIf) throws IOException(Code) Leave the multicast group. Parameters:   multicast - address to leave. Parameters:   netIf - specified the local interface to leave the group at throws:   IllegalArgumentException - if mcastaddr is null or is aSocketAddress subclass not supported by this socket since:    1.4 peek native protected synchronized int peek(InetAddress i) throws IOException(Code) Peek at the packet to see who it is from. return the address which the packet came from. peekData native protected synchronized int peekData(DatagramPacket p) throws IOException(Code) receive native protected synchronized void receive(DatagramPacket p) throws IOException(Code) Receive the datagram packet. Parameters:   Packet - Received. send native protected void send(DatagramPacket p) throws IOException(Code) Sends a datagram packet. The packet contains the data and the destination address to send the packet to. Parameters:   packet - to be sent. setOption public void setOption(int optID, Object o) throws SocketException(Code) set a value - since we only support (setting) binary options here, o must be a Boolean setTimeToLive native protected void setTimeToLive(int ttl) throws IOException(Code) Set the TTL (time-to-live) option. Parameters:   TTL - to be set.
