getUseSendQueues

public boolean getUseSendQueues()

setUseSendQueues

public void setUseSendQueues(boolean flag)

getSendQueueSize

public int getSendQueueSize()

setSendQueueSize

public void setSendQueueSize(int send_queue_size)

start

public void start()
           throws java.lang.Exception

Throws:

java.lang.Exception

stop

public void stop()

removeConnection

public void removeConnection(Address addr)

Remove addrfrom connection table. This is typically triggered when a member is suspected.

receive

public void receive(Address sender,
                    byte[] data,
                    int offset,
                    int length)

Calls the receiver callback. We do not serialize access to this method, and it may be called concurrently by several Connection handler threads. Therefore the receiver needs to be reentrant.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

send

public void send(Address dest,
                 byte[] data,
                 int offset,
                 int length)
          throws java.lang.Exception

Throws:

java.lang.Exception

retainAll

public void retainAll(java.util.Collection<Address> current_mbrs)

Removes all connections from ConnectionTable which are not in current_mbrs

Parameters:

current_mbrs -
