Package org.jgroups.protocols

Class BPING

java.lang.Object
org.jgroups.stack.Protocol
org.jgroups.protocols.Discovery
org.jgroups.protocols.PING
org.jgroups.protocols.BPING
All Implemented Interfaces:
Runnable
public class BPING extends PING implements Runnable
Broadcast PING. Uses UDP broadcasts to discover initial membership. This protocol is useless in IPv6 environments, as IPv6 has no notion of broadcast addresses. Use IP multicasts instead (e.g. PING or MPING) when running in IPv6.

  • Method Details

    • getBindPort

      public int getBindPort()

    • setBindPort

      public void setBindPort(int bind_port)

    • init

      public void init() throws Exception
      Description copied from class: Protocol
      Called after instance has been created (null constructor) and before protocol is started. Properties are already set. Other protocols are not yet connected and events cannot yet be sent.
      Overrides:
      init in class Discovery
      Throws:
      Exception - Thrown if protocol cannot be initialized successfully. This will cause the ProtocolStack to fail, so the channel constructor will throw an exception

    • start

      public void start() throws Exception
      Description copied from class: Protocol
      This method is called on a Channel.connect(String). Starts work. Protocols are connected and queues are ready to receive events. Will be called from bottom to top. This call will replace the START and START_OK events.
      Overrides:
      start in class Discovery
      Throws:
      Exception - Thrown if protocol cannot be started successfully. This will cause the ProtocolStack to fail, so Channel.connect(String) will throw an exception

    • 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 PING

    • run

      public void run()
      Specified by:
      run in interface Runnable
