Functions ¶
Types ¶
type Etcd ¶
type Etcd struct {
// contains filtered or unexported fields
}
Etcd is the receiver type for the Store interface
func (*Etcd) 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 (*Etcd) AtomicPut ¶
func (s *Etcd) AtomicPut(key string, value []byte, previous *store.KVPair, opts *store.WriteOptions) (bool, *store.KVPair, error)
AtomicPut puts a value at "key" if the key has not been modified in the meantime, throws an error if this is the case
func (*Etcd) DeleteTree ¶
DeleteTree deletes a range of keys under a given directory
func (*Etcd) Get ¶
Get the value at "key", returns the last modified index to use in conjunction to Atomic calls
func (*Etcd) NewLock ¶
NewLock returns a handle to a lock struct which can be used to provide mutual exclusion on a key
func (*Etcd) 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.
