DeleteBuilderImpl(CuratorFrameworkImpl client, int version, Backgrounding backgrounding, boolean deletingChildrenIfNeeded, boolean guaranteed, boolean quietly)

Method Summary

Modifier and Type	Method	Description
BackgroundVersionable	deletingChildrenIfNeeded()	Will also delete children if they exist.
Void	forPath(String path)	Commit the currently building operation using the given path
CuratorEventType	getBackgroundEventType()
protected int	getVersion()
ChildrenDeletable	guaranteed()	Solves edge cases where an operation may succeed on the server but connection failure occurs before a response can be successfully returned to the client.
DeleteBuilderMain	idempotent()	If the first try of this operation gets a transient error, curator will retry the operation, and treat it as successful so long as the end state of the znode is the same as if the operation had completed without error on the first try.
ErrorListenerPathable<Void>	inBackground()	Perform the action in the background
ErrorListenerPathable<Void>	inBackground(Object context)	Perform the action in the background
ErrorListenerPathable<Void>	inBackground(BackgroundCallback callback)	Perform the action in the background
ErrorListenerPathable<Void>	inBackground(BackgroundCallback callback, Object context)	Perform the action in the background
ErrorListenerPathable<Void>	inBackground(BackgroundCallback callback, Object context, Executor executor)	Perform the action in the background
ErrorListenerPathable<Void>	inBackground(BackgroundCallback callback, Executor executor)	Perform the action in the background
void	performBackgroundOperation(org.apache.curator.framework.imps.OperationAndData<String> operationAndData)
DeleteBuilderMain	quietly()
Pathable<Void>	withUnhandledErrorListener(UnhandledErrorListener listener)	Set an error listener for this background operation.
BackgroundPathable<Void>	withVersion(int version)	Use the given version (the default is -1)
