public class TCP extends BasicTCP
TCP based protocol. Creates a server socket, which gives us the local address of this group member. For each accept() on the server socket, a new thread is created that listens on the socket. For each outgoing message m, if m.dest is in the outgoing hash table, the associated socket will be reused to send message, otherwise a new socket is created and put in the hash table. When a socket connection breaks or a member is removed from the group, the corresponding items in the incoming and outgoing hash tables will be removed as well.This functionality is in TcpServer, which is used by TCP. TCP sends messages using ct.send() and registers with the connection table to receive all incoming messages.

setSocketFactory
public void setSocketFactory(SocketFactory factory)
Description copied from class:Protocol
Sets a SocketFactory. Socket factories are typically provided by the transport (TP
)- Overrides:
setSocketFactory
in classTP
-
send
public void send(Address dest, byte[] data, int offset, int length) throws java.lang.Exception
-
retainAll
public void retainAll(java.util.Collection<Address> members)
-
start
public void start() throws java.lang.Exception
Description copied from class:TP
Creates the unicast and multicast sockets and starts the unicast and multicast receiver threads- Overrides:
start
in classTP
- Throws:
java.lang.Exception
- Thrown if protocol cannot be started successfully. This will cause the ProtocolStack to fail, soJChannel.connect(String)
will throw an exception
-
stop
public void stop()
Description copied from class:Protocol
This method is called on aJChannel.disconnect()
. Stops work (e.g. by closing multicast socket). Will be called from top to bottom. This means that at the time of the method invocation the neighbor protocol below is still working. This method will replace the STOP, STOP_OK, CLEANUP and CLEANUP_OK events. The ProtocolStack guarantees that when this method is called all messages in the down queue will have been flushed

handleConnect

protected void handleDisconnect()
