Detailed Description

ZKLock is a globally synchronous lock that is implemented using ZooKeeper. Multiple clients can synchronize on a resource by locking onto the same path.

ZKLock::ZKLock ( ZKWrapper &  zkWrapper, std::string  path  )

inline

Parameters

zkWrapper
path	the path to lock onto. This path does not need to exist inside ZooKeeper.

Returns
