org.eclipse.persistence.sessions.coordination.CommandManager
Purpose: Provide an interface that clients can use to invoke remote commands on other TopLink instances, or on other applications that may want to receive and process TopLink commands.
Description: This is the main interface that is used to send and receive remote commands in a TopLink cluster. The sequence of remote command execution is as follows:
1. CommandProcessor creates a command and gives it to its local CommandManager to send to remote services.
2. CommandManager uses its CommandConverter to convert the command into a TopLink Command object
3. CommandManager then uses its TransportManager to send the Command to all other known cluster members that are subscribing to the same channel
4. Each remote TransportManager receives the Command and passes it off to the CommandManager
5. Each CommandManager uses its local CommandConverter to convert the command into a format appropriate to its application (CommandProcessor)
6. Each CommandManager invokes its local CommandProcessor and passes it the command (formatted the way that the application-specified converter left it in) to be executed. If the CommandProcessor is a TopLink session then the executeWithSession method will be invoked on the command.
Responsibilities:
- Invoke the DiscoveryManager to establish the TopLink cluster
- Propagate remote command to TopLink cluster
- Delegate processing command to its CommandProssesor
- Convert command to appropriate format for sending to TopLink cluster or its command processor
