Functions ¶
Types ¶
type Zookeeper ¶
type Zookeeper struct {
// contains filtered or unexported fields
}
Zookeeper is the receiver type for the Store interface
func (*Zookeeper) AtomicDelete ¶
AtomicDelete deletes a value at "key" if the key has not been modified in the meantime, throws an error if this is the case
func (*Zookeeper) AtomicPut ¶
func (s *Zookeeper) AtomicPut(key string, value []byte, previous *store.KVPair, _ *store.WriteOptions) (bool, *store.KVPair, error)
AtomicPut put a value at "key" if the key has not been modified in the meantime, throws an error if this is the case
func (*Zookeeper) DeleteTree ¶
DeleteTree deletes a range of keys under a given directory
func (*Zookeeper) Get ¶
Get the value at "key", returns the last modified index to use in conjunction to Atomic calls
func (*Zookeeper) NewLock ¶
NewLock returns a handle to a lock struct which can be used to provide mutual exclusion on a key
func (*Zookeeper) Watch ¶
Watch for changes on a "key" It returns a channel that will receive changes or pass on errors. Upon creation, the current value will first be sent to the channel. Providing a non-nil stopCh can be used to stop watching.
func (*Zookeeper) WatchTree ¶
func (s *Zookeeper) WatchTree(directory string, stopCh <-chan struct{}) (<-chan []*store.KVPair, error)
WatchTree watches for changes on a "directory" It returns a channel that will receive changes or pass on errors. Upon creating a watch, the current childs values will be sent to the channel .Providing a non-nil stopCh can be used to stop watching.
