func NewEtcdStorage

func NewEtcdStorage(client etcd.Client, codec runtime.Codec, prefix string, quorum bool) storage.Interface

Creates a new storage interface from the client TODO: deprecate in favor of storage.Config abstraction over time

Types

type APIObjectVersioner

type APIObjectVersioner struct{}

APIObjectVersioner implements versioning and extracting etcd node information for objects that have an embedded ObjectMeta or ListMeta field.

func (APIObjectVersioner) ObjectResourceVersion

func (a APIObjectVersioner) ObjectResourceVersion(obj runtime.Object) (uint64, error)

ObjectResourceVersion implements Versioner

func (APIObjectVersioner) UpdateList

func (a APIObjectVersioner) UpdateList(obj runtime.Object, resourceVersion uint64) error

UpdateList implements Versioner

func (APIObjectVersioner) UpdateObject

func (a APIObjectVersioner) UpdateObject(obj runtime.Object, expiration *time.Time, resourceVersion uint64) error

UpdateObject implements Versioner

type EtcdConfig

type EtcdConfig struct {
	ServerList []string
	Codec      runtime.Codec
	Prefix     string
	Quorum     bool
}

storage.Config object for etcd.

func (*EtcdConfig) GetType

func (c *EtcdConfig) GetType() string

implements storage.Config

func (*EtcdConfig) NewStorage

func (c *EtcdConfig) NewStorage() (storage.Interface, error)

implements storage.Config

type HighWaterMark

type HighWaterMark int64

HighWaterMark is a thread-safe object for tracking the maximum value seen for some quantity.

func (*HighWaterMark) Update

func (hwm *HighWaterMark) Update(current int64) bool

Update returns true if and only if 'current' is the highest value ever seen.

type TransformFunc

type TransformFunc func(runtime.Object) (runtime.Object, error)

TransformFunc attempts to convert an object to another object for use with a watcher.
