java.lang.Object |
down(Event evt) |
An event is to be sent down the stack.
|
java.lang.String |
getName() |
|
void |
init() |
Called after instance has been created (null constructor) and before protocol is started.
|
void |
run() |
Will be started when a suspect is added to the suspects hashtable.
|
boolean |
setProperties(java.util.Properties props) |
Configures the protocol initially.
|
void |
start() |
This method is called on a
Channel.connect(String) . |
void |
stop() |
This method is called on a
Channel.disconnect() . |
java.lang.Object |

Protocol
down_prot.down()
. In case of a GET_ADDRESS event (which tries to
retrieve the stack's address from one of the bottom layers), the layer may need to send
a new response event back up the stack using up_prot.up()

public void start() throws java.lang.Exception
Protocol
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.start
in class Protocol
java.lang.Exception
- Thrown if protocol cannot be started successfully. This will cause the ProtocolStack
to fail, so Channel.connect(String)
will throw an exceptionpublic void stop()
Protocol
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 flushedCopyright ? 1998-2008 Bela Ban. All Rights Reserved.
