func GroupHandler ¶

func GroupHandler(s runtime.NegotiatedSerializer, group metav1.APIGroup) restful.RouteFunction

GroupHandler returns a handler which will return the api.GroupAndVersion of the group.

func ListResource ¶

func ListResource(r rest.Lister, rw rest.Watcher, scope RequestScope, forceWatch bool, minRequestTimeout time.Duration) restful.RouteFunction

ListResource returns a function that handles retrieving a list of resources from a rest.Storage object.

func PatchResource ¶

func PatchResource(r rest.Patcher, scope RequestScope, admit admission.Interface, converter runtime.ObjectConvertor) restful.RouteFunction

PatchResource returns a function that will handle a resource patch TODO: Eventually PatchResource should just use GuaranteedUpdate and this routine should be a bit cleaner

func RootAPIHandler ¶

func RootAPIHandler(s runtime.NegotiatedSerializer, f func(req *restful.Request) []metav1.APIGroup) restful.RouteFunction

RootAPIHandler returns a handler which will list the provided groups and versions as available.

func SupportedResourcesHandler ¶

func SupportedResourcesHandler(s runtime.NegotiatedSerializer, groupVersion schema.GroupVersion, lister APIResourceLister) restful.RouteFunction

SupportedResourcesHandler returns a handler which will list the provided resources as available.

func UpdateResource ¶

func UpdateResource(r rest.Updater, scope RequestScope, typer runtime.ObjectTyper, admit admission.Interface) restful.RouteFunction

Types ¶

type APIResourceLister ¶

type APIResourceLister interface {
	ListAPIResources() []metav1.APIResource
}

type ContextFunc ¶

type ContextFunc func(req *restful.Request) request.Context

ContextFunc returns a Context given a request - a context must be returned

type ProxyHandler ¶

type ProxyHandler struct {
	Prefix     string
	Storage    map[string]rest.Storage
	Serializer runtime.NegotiatedSerializer
	Mapper     request.RequestContextMapper
}

ProxyHandler provides a http.Handler which will proxy traffic to locations specified by items implementing Redirector.

func (*ProxyHandler) ServeHTTP ¶

func (r *ProxyHandler) ServeHTTP(w http.ResponseWriter, req *http.Request)

type RequestScope ¶

type RequestScope struct {
	Namer ScopeNamer
	ContextFunc

	Serializer runtime.NegotiatedSerializer
	runtime.ParameterCodec

	Creater   runtime.ObjectCreater
	Convertor runtime.ObjectConvertor
	Copier    runtime.ObjectCopier

	Resource    schema.GroupVersionResource
	Kind        schema.GroupVersionKind
	Subresource string

	MetaGroupVersion schema.GroupVersion
}

RequestScope encapsulates common fields across all RESTful handler methods.

type ScopeNamer ¶

type ScopeNamer interface {
	// Namespace returns the appropriate namespace value from the request (may be empty) or an
	// error.
	Namespace(req *restful.Request) (namespace string, err error)
	// Name returns the name from the request, and an optional namespace value if this is a namespace
	// scoped call. An error is returned if the name is not available.
	Name(req *restful.Request) (namespace, name string, err error)
	// ObjectName returns the namespace and name from an object if they exist, or an error if the object
	// does not support names.
	ObjectName(obj runtime.Object) (namespace, name string, err error)
	// SetSelfLink sets the provided URL onto the object. The method should return nil if the object
	// does not support selfLinks.
	SetSelfLink(obj runtime.Object, url string) error
	// GenerateLink creates an encoded URI for a given runtime object that represents the canonical path
	// and query.
	GenerateLink(req *restful.Request, obj runtime.Object) (uri string, err error)
	// GenerateLink creates an encoded URI for a list that represents the canonical path and query.
	GenerateListLink(req *restful.Request) (uri string, err error)
}

ScopeNamer handles accessing names from requests and objects

type TimeoutFactory ¶

type TimeoutFactory interface {
	TimeoutCh() (<-chan time.Time, func() bool)
}

timeoutFactory abstracts watch timeout logic for testing

type WatchServer ¶

type WatchServer struct {
	Watching watch.Interface
	Scope    RequestScope

	// true if websocket messages should use text framing (as opposed to binary framing)
	UseTextFraming bool
	// the media type this watch is being served with
	MediaType string
	// used to frame the watch stream
	Framer runtime.Framer
	// used to encode the watch stream event itself
	Encoder runtime.Encoder
	// used to encode the nested object in the watch stream
	EmbeddedEncoder runtime.Encoder
	Fixup           func(runtime.Object)

	TimeoutFactory TimeoutFactory
