Class BPING

  • All Implemented Interfaces:
    java.lang.Runnable, Lifecycle
    public class BPING
extends PING
implements java.lang.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.

      • init

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

           throws java.lang.Exception
        Description copied from class: Protocol

        Overrides:
        start in class Discovery
