Method Details

getConnectionTable

protected ConnectionTableNIO getConnectionTable(long ri,
 long cet,
 InetAddress b_addr,
 InetAddress bc_addr,
 int s_port,
 int e_port)
                                         throws Exception

Throws:

Exception

printConnections

public String printConnections()

Specified by:

printConnections in class BasicTCP

getPhysicalAddress

protected PhysicalAddress getPhysicalAddress()

Specified by:

getPhysicalAddress in class TP

send

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

Specified by:

send in class BasicTCP

Throws:

Exception

start

public void start()
           throws Exception

Description copied from class: TP

Creates the unicast and multicast sockets and starts the unicast and multicast receiver threads

Overrides:

start in class TP

Throws:

Exception - Thrown if protocol cannot be started successfully. This will cause the ProtocolStack to fail, so Channel.connect(String) will throw an exception

retainAll

public void retainAll(Collection<Address> members)

Specified by:

retainAll in class BasicTCP

stop

public void stop()

Description copied from class: Protocol

This method is called on a Channel.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

Overrides:

stop in class TP

getReaderThreads

public int getReaderThreads()

getWriterThreads

public int getWriterThreads()

getProcessorThreads

public int getProcessorThreads()

getProcessorMinThreads

public int getProcessorMinThreads()

getProcessorMaxThreads

public int getProcessorMaxThreads()

getProcessorQueueSize

public int getProcessorQueueSize()

getProcessorKeepAliveTime

public long getProcessorKeepAliveTime()

getOpenConnections

public int getOpenConnections()
