Method Detail

getMaster

org.neo4j.helpers.Pair<Master,Machine> getMaster()

getMasterReally

org.neo4j.helpers.Pair<Master,Machine> getMasterReally(boolean allowChange)

getMasterExceptMyself

Machine getMasterExceptMyself()

setLastCommittedTxId

void setLastCommittedTxId(long txId)

iAmMaster

boolean iAmMaster()

getMyMachineId

int getMyMachineId()

instantiateMasterServer

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

rebindMaster

void rebindMaster()

notifyMasterChange

void notifyMasterChange(Machine newMaster)

shutdown

void shutdown()

restart

void restart()

start

void start()

setConnectionInformation

void setConnectionInformation(org.neo4j.kernel.KernelData kernel)

getConnectionInformation

ConnectionInformation getConnectionInformation(int machineId)

getConnectionInformation

ConnectionInformation[] getConnectionInformation()

getClusterStoreId

org.neo4j.kernel.impl.nioneo.store.StoreId getClusterStoreId(boolean firstTime)

Asks the cluster for and returns the storeId currently shared by the cluster members or a new one if none is there.

Parameters:

firstTime - False if it should timeout after a session interval passes - expected to be true in the same scenarios where bootstrap() is called instead of getMasterReally(boolean)

Returns:

The storeId existing in the cluster or a new one if none is found

logStatus

void logStatus(org.neo4j.kernel.impl.util.StringLogger msgLog)

bootstrap

org.neo4j.helpers.Pair<Master,Machine> bootstrap()
