Variables ¶

var Versioner storage.Versioner = APIObjectVersioner{}

APIObjectVersioner implements Versioner

Functions ¶

func NewEtcdStorage ¶

func NewEtcdStorage(client etcd.Client, codec runtime.Codec, prefix string, quorum bool, cacheSize int) 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) CompareResourceVersion ¶

func (a APIObjectVersioner) CompareResourceVersion(lhs, rhs runtime.Object) int

CompareResourceVersion compares etcd resource versions. Outside this API they are all strings, but etcd resource versions are special, they're actually ints, so we can easily compare them.

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, resourceVersion uint64) error

UpdateObject implements Versioner

type TransformFunc ¶

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

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