Method Detail

addListener

void addListener(DistributedBusMemberListener listener,
                 List<PeerCard> nodes)

Add a new listener.

Parameters:

listener - The callback that is invoked when a change occurs.

nodes - The set of nodes on which the listener should be added. An empty list will subscribe to all nodes, including nodes that will join the space in the future. Null will subscribe to this node only and is equivalent with a list that contains the PeerCard of this node.

removeListener

void removeListener(DistributedBusMemberListener listener,
                    List<PeerCard> nodes)

Remove an existing listener.

Parameters:

listener - The callback that was registered before with addListener(DistributedBusMemberListener, List).

nodes - The set of nodes on which the listener should be removed. An empty list will unsubscribe from all nodes. Null will unsubscribe from this node only and is equivalent with a list that contains the PeerCard of this node.
