Method Detail

getBroker

public Broker getBroker()

pullUpdates

public void pullUpdates()

getConfig

public org.neo4j.kernel.Config getConfig()

Specified by:

getConfig in class org.neo4j.kernel.AbstractGraphDatabase

getStoreDir

public String getStoreDir()

Specified by:

getStoreDir in class org.neo4j.kernel.AbstractGraphDatabase

getManagementBeans

public <T> Collection<T> getManagementBeans(Class<T> type)

Specified by:

toString

public String toString()

Overrides:

toString in class org.neo4j.kernel.AbstractGraphDatabase

reconnect

public void reconnect(Exception e)

Shuts down the broker, invalidating every connection to the zookeeper cluster and starts it again. Should be called in case a ConnectionExpired event is received, this is the equivalent of building the ZK connection from start. Also triggers a master reelect, to make sure that the state ZK ended up in during our absence is respected. The cluster manager is not used outside of startup where this call should not happen and also it doesn't keep a zoo client open - so is no reason to recreate it

Specified by:

reconnect in interface ResponseReceiver
