Exception

getBackgroundEventType

public CuratorEventType getBackgroundEventType()

Most events are delivered by operations themselves, so they know their event types. But in occasional cases(says, closing or background exception), events are delivered by curator framework.

performBackgroundOperation

public void performBackgroundOperation(org.apache.curator.framework.imps.OperationAndData<Void> operationAndData)
                                throws Exception

Throws:

Exception
