var Versioner storage.Versioner = APIObjectVersioner{}

Versioner implements Versioner

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) ParseResourceVersion ¶

func (a APIObjectVersioner) ParseResourceVersion(resourceVersion string) (uint64, error)

ParseResourceVersion takes a resource version argument and converts it to the etcd version. For watch we should pass to helper.Watch(). Because resourceVersion is an opaque value, the default watch behavior for non-zero watch is to watch the next value (if you pass "1", you will see updates from "2" onwards).

func (APIObjectVersioner) PrepareObjectForStorage ¶

func (a APIObjectVersioner) PrepareObjectForStorage(obj runtime.Object) error

PrepareObjectForStorage clears resource version and self link prior to writing to etcd.

func (APIObjectVersioner) UpdateList ¶

func (a APIObjectVersioner) UpdateList(obj runtime.Object, resourceVersion uint64, nextKey string, count *int64) error

UpdateList implements Versioner

func (APIObjectVersioner) UpdateObject ¶

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

UpdateObject implements Versioner
