Method Detail

createDiscoveryManager

public DiscoveryManager createDiscoveryManager()

ADVANCED: BroadcastTransportManager doesn't use DiscoveryManager - instead RemoteCommandManager calls createConnections method during initialization.

Overrides:

createDiscoveryManager in class TransportManager

createConnections

public void createConnections()

INTERNAL: BroadcastTransportManager doesn't use DiscoveryManager (createDiscoveryManager method returns null) therefore this method called during RCM initialization to create all the necessary connections. BroadcastTransportManager ancestors may need to override this method.

Overrides:

createConnections in class TransportManager

createConnection

public org.eclipse.persistence.internal.sessions.coordination.RemoteConnection createConnection(ServiceId serviceId)

INTERNAL: No-op implementation of super abstract method since there is only one connection to a known topic.

Specified by:

createConnection in class TransportManager

addConnectionToExternalService

public void addConnectionToExternalService(org.eclipse.persistence.internal.sessions.coordination.RemoteConnection connection)

INTERNAL: Add a remote Connection to a remote service.

Overrides:

addConnectionToExternalService in class TransportManager

connectBackToRemote

public void connectBackToRemote(org.eclipse.persistence.internal.sessions.coordination.RemoteConnection connection)
                         throws java.lang.Exception

INTERNAL: Prepare receiving messages by registering this connection as a listener to the Subscriber. This method is called by the remote command manager when this service should connect back ('handshake') to the service from which this remote connection came.

Overrides:

connectBackToRemote in class TransportManager

Throws:

java.lang.Exception

getTopicName

public java.lang.String getTopicName()

PUBLIC: Return the topic name that this TransportManager will be connecting to.

setTopicName

public void setTopicName(java.lang.String newTopicName)

PUBLIC: Configure the Topic name for the Topic that this TransportManager will be connecting to. For some subclasses (JMS) this is a required setting and must be set; for other (Oc4jJGroups) it's typically not set.
