ZooClient

public ZooClient(String storeDir,
                 org.neo4j.kernel.impl.util.StringLogger stringLogger,
                 org.neo4j.kernel.configuration.Config conf,

                 ClusterEventReceiver clusterReceiver,
                 MasterClientFactory clientFactory)

Method Detail

instantiateMasterServer

public Object instantiateMasterServer(org.neo4j.kernel.GraphDatabaseAPI graphDb)

getStoreId

protected org.neo4j.kernel.impl.nioneo.store.StoreId getStoreId()

Overrides:

getStoreId in class AbstractZooKeeperManager

instantiateSlaveServer

public Object instantiateSlaveServer(org.neo4j.kernel.GraphDatabaseAPI graphDb,
                                     Broker broker,
                                     SlaveDatabaseOperations ops)

getMyMachineId

protected int getMyMachineId()

Specified by:

getMyMachineId in class AbstractZooKeeperManager

subscribeToDataChangeWatcher

protected void subscribeToDataChangeWatcher(String child)

subscribeToChildrenChangeWatcher

protected void subscribeToChildrenChangeWatcher(String child)

setDataChangeWatcher

protected void setDataChangeWatcher(String child,
                                    int currentMasterId)

setDataChangeWatcher

protected void setDataChangeWatcher(String child,
                                    int currentMasterId,
                                    boolean skipOnSame)

Writes into one of master-notify or master-rebound the value given. If skipOnSame is true then if the value there is the same as the argument nothing will be written. A watch is always set on the node.

Parameters:

child - The node to write to

currentMasterId - The value to write

skipOnSame - If true, then if the existing value is the same as currentMasterId nothing will be written.
