Types

type APIObjectVersioner

type APIObjectVersioner struct{}

APIObjectVersioner implements versioning and extracting mysql 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) ParseListResourceVersion

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

ParseListResourceVersion takes a resource version argument and converts it to the etcd version. TODO: reevaluate whether it is really clearer to have both this and the Watch version of this function, since they perform the same logic.

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) ParseWatchResourceVersion

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

ParseWatchResourceVersion takes a resource version argument and converts it to the etcd version 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

type Collection

type Collection struct {
	// contains filtered or unexported fields
}

func GetCollection

func GetCollection(dbName string, sess *mgo.Session, obj runtime.Object) (*Collection, error)

func (*Collection) CreateIndex

func (c *Collection) CreateIndex(meta *client.RequestMeta) error

CreateIndex by runtime object

func (*Collection) GetRequestMeta

func (c *Collection) GetRequestMeta(sess *mgo.Session) *client.RequestMeta

type DocObject

type DocObject struct {
	TTL    time.Time `bson:"ttl"`
	UID    types.UID `bson:"uid"`
	Key    string    `bson:"key"`
	Object []byte    `bson:"obj"`
}

type Document

type Document struct {
	TTL    time.Time
	Object runtime.Object
}

func NewDocument

func NewDocument(ttl uint64, obj runtime.Object) *Document

func (*Document) Decode

func (doc *Document) Decode(codec runtime.Codec) (interface{}, error)

func (*Document) Encode

func (doc *Document) Encode(codec runtime.Codec, key string) (interface{}, error)
