org.jgroups.blocks.ConnectionTable
public class ConnectionTable
Manages incoming and outgoing TCP connections. For each outgoing message to destination P, if there
is not yet a connection for P, one will be created. Subsequent outgoing messages will use this
connection. For incoming messages, one server socket is created at startup. For each new incoming
client connecting, a new thread from a thread pool is allocated and listens for incoming messages
until the socket is closed by the peer.
Sockets/threads with no activity will be killed
after some time.
Incoming messages from any of the sockets can be received by setting the message listener.

public ConnectionTable(int srv_port) throws java.lang.Exception
srv_port
- The port on which the server will listen. If this port is reserved, the next
free port will be taken (incrementing srv_port).

srv_port
- The port on which the server will listenreaper_interval
- Number of milliseconds to wait for reaper between attepts to reap idle connectionsconn_expire_time
- Number of milliseconds a connection can be idle (no traffic sent or received until
it will be reaped
java.lang.Exception
public ConnectionTable(BasicConnectionTable.Receiver r, java.net.InetAddress bind_addr, java.net.InetAddress external_addr, int srv_port, int max_port) throws java.lang.Exception
r
- A reference to a receiver of all messages received by this class. Method receive()
will be called.bind_addr
- The host name or IP address of the interface to which the server socket will bind.
This is interesting only in multi-homed systems. If bind_addr is null, the
server socket will bind to the first available interface (e.g. /dev/hme0 on
Solaris or /dev/eth0 on Linux systems).external_addr
- The address which will be broadcast to the group (the externally visible address
which this host should be contacted on). If external_addr is null, it will default to
the same address that the server socket is bound to.srv_port
- The port to which the server socket will bind to. If this port is reserved, the next
free port will be taken (incrementing srv_port).max_port
- The largest port number that the server socket will be bound to. If max_port < srv_port
then there is no limit.
