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 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
