Constructor Detail

ZooClient

public ZooClient(AbstractGraphDatabase graphDb,
                 Map<String,String> config,
                 ResponseReceiver receiver)

Method Detail

flushUnprocessedEvents

protected void flushUnprocessedEvents(org.apache.zookeeper.ZooKeeper zooKeeper)

Flush all events we go before initialization of ZooKeeper/WatcherImpl was completed.

Parameters:

zooKeeper - ZooKeeper instance to use when processing. We cannot rely on the zooKeeper instance inherited from ZooClient since the contract says that such fields are only guaranteed to be published when the constructor has returned, and at this point it hasn't.
