type ScopeNamer

type ScopeNamer interface {
	// Namespace returns the appropriate namespace value from the request (may be empty) or an
	// error.
	Namespace(req *http.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 *http.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)
