Method Detail

getMaster

Pair<Master,Machine> getMaster()

getMasterReally

Pair<Master,Machine> getMasterReally(boolean allowChange)

getMasterExceptMyself

Machine getMasterExceptMyself()

setLastCommittedTxId

void setLastCommittedTxId(long txId)

iAmMaster

boolean iAmMaster()

getMyMachineId

int getMyMachineId()

instantiateMasterServer

Object instantiateMasterServer(GraphDatabaseService graphDb)

rebindMaster

void rebindMaster()

notifyMasterChange

void notifyMasterChange(Machine newMaster)

shutdown

void shutdown()

restart

void restart()

start

void start()

setConnectionInformation

void setConnectionInformation(KernelData kernel)

getConnectionInformation

ConnectionInformation getConnectionInformation(int machineId)

getConnectionInformation

ConnectionInformation[] getConnectionInformation()

getClusterStoreId

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(StringLogger msgLog)

bootstrap

Pair<Master,Machine> bootstrap()
