MetaFactory

type MetaFactory interface {
    // Interpret should return the version and kind of the wire-format of
    // the object.
    Interpret(data []byte) (*schema.GroupVersionKind, error)
}

SimpleMetaFactory

func (SimpleMetaFactory) Interpret(data []byte) (*schema.GroupVersionKind, error) {
    findKind := struct {
        // +optional
        APIVersion string `json:"apiVersion,omitempty"`
        // +optional
        Kind string `json:"kind,omitempty"`
    }{}
    if err := json.Unmarshal(data, &findKind); err != nil {
        return nil, fmt.Errorf("couldn't get version/kind; json parse error: %v", err)
    }
    gv, err := schema.ParseGroupVersion(findKind.APIVersion)
    if err != nil {
        return nil, err
    }
    return &schema.GroupVersionKind{Group: gv.Group, Version: gv.Version, Kind: findKind.Kind}, nil

全局定义

var serializerExtensions = []func(*runtime.Scheme) (serializerType, bool){}

加载过程

func newSerializersForScheme(scheme *runtime.Scheme, mf json.MetaFactory) []serializerType {
    // ...
    for _, fn := range serializerExtensions {
        if serializer, ok := fn(scheme); ok {
            serializers = append(serializers, serializer)
        }
    }
    return serializers
}
