@Deprecated public class TOA extends Protocol implements DeliveryProtocol
Deprecated.Will get removed from JGroups when Infinispan does not use it anymoreTotal Order Anycast with three communication steps (based on Skeen's Algorithm). Establishes total order for a message sent to a subset of the cluster members (an anycast). Example: send a totally ordered message to {D,E} out of a membership of {A,B,C,D,E,F}. Skeen's algorithm uses consensus among the anycast target members to find the currently highest sequence number (seqno) and delivers the message according to the order established by the seqnos.- Since:

Method Detail
-
start
public void start() throws java.lang.Exception
Deprecated.Description copied from class:Protocol
This method is called on aJChannel.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 classProtocol
- Throws:
java.lang.Exception
- Thrown if protocol cannot be started successfully. This will cause the ProtocolStack to fail, soJChannel.connect(String)
will throw an exception
-
stop
public void stop()
Deprecated.Description copied from class:Protocol
This method is called on aJChannel.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
-
down
public java.lang.Object down(Event evt)
Deprecated.Description copied from class:Protocol
An event is to be sent down the stack. A protocol may want to examine its type and perform some action on it, depending on the event's type. If the event is a message MSG, then the protocol may need to add a header to it (or do nothing at all) before sending it down the stack usingdown_prot.down()
.
-
down
public java.lang.Object down(Message message)
Deprecated.Description copied from class:Protocol
A message is sent down the stack. Protocols may examine the message and do something (e.g. add a header) with it before passing it down.
-
up
public java.lang.Object up(Event evt)
Deprecated.Description copied from class:Protocol
An event was received from the protocol below. Usually the current protocol will want to examine the event type and - depending on its type - perform some computation (e.g. removing headers from a MSG event type, or updating the internal membership list when receiving a VIEW_CHANGE event). Finally the event is either a) discarded, or b) an event is sent down the stack usingdown_prot.down()
or c) the event (or another event) is sent up the stack usingup_prot.up()
.
-
up
public java.lang.Object up(Message message)
Deprecated.Description copied from class:Protocol
A single message was received. Protocols may examine the message and do something (e.g. add a header) with it before passing it up.
