Method Detail

connect

public void connect()

Description copied from interface: Cluster

Connects to the current Reveno group of nodes. Depending on the concrete implementation, either physical connection is opened (TCP protocol for example), or not (UPD protocol for example). In any case, it allows to performs much of initialization things.

Specified by:

connect in interface Cluster

disconnect

public void disconnect()

Description copied from interface: Cluster

Marks itself as detached from the cluster, and frees all allocated resources and connections for it.

Specified by:

disconnect in interface Cluster

isConnected

public boolean isConnected()

Description copied from interface: Cluster

Checks whether current node is included in current group of hosts.

Specified by:

isConnected in interface Cluster

Returns:

gateway

public ClusterConnector gateway()

Description copied from interface: Cluster

Provides gateway instance which provides with communication ability between nodes via sending Messages to each other.

Specified by:

gateway in interface Cluster

Returns:

marshallWith

public void marshallWith(Marshaller marshaller)

Description copied from interface: Cluster

Sets the marshaller instance, which will be used to marshall/unmarshall all incoming/outgoing messages. Surely, all nodes in cluster should use the same one.

Specified by:

marshallWith in interface Cluster

listenEvents

public void listenEvents(java.util.function.Consumer<ClusterEvent> consumer)

Description copied from interface: Cluster

Subscribes to the set of events, which can eventually be issued, reflecting some changes in membership, etc.

Specified by:

listenEvents in interface Cluster

view

public ClusterView view()

Description copied from interface: Cluster

Returns the current Reveno Cluster View. It is represented by unique nubmer and the list of current active members which are in current group. If new node(s) comes in/out of the cluster, new View instance is registered among all rest active nodes, which in turn require new leadership election process to be started.

Specified by:

view in interface Cluster

Returns:
