Types

type Codec

type Codec Serializer

Codec is a Serializer that deals with the details of versioning objects. It offers the same interface as Serializer, so this is a marker to consumers that care about the version of the objects they receive.

var UnstructuredJSONScheme Codec = unstructuredJSONScheme{}

UnstructuredJSONScheme is capable of converting JSON data into the Unstructured type, which can be used for generic access to objects without a predefined scheme. TODO: move into serializer/json.

func NewCodec

func NewCodec(e Encoder, d Decoder) Codec

NewCodec creates a Codec from an Encoder and Decoder.

type Decoder

type Decoder interface {
	// Decode attempts to deserialize the provided data using either the innate typing of the scheme or the
	// default kind, group, and version provided. It returns a decoded object as well as the kind, group, and
	// version from the serialized data, or an error. If into is non-nil, it will be used as the target type
	// and implementations may choose to use it rather than reallocating an object. However, the object is not
	// guaranteed to be populated. The returned object is not guaranteed to match into. If defaults are
	// provided, they are applied to the data by default. If no defaults or partial defaults are provided, the
	// type of the into may be used to guide conversion decisions.
	Decode(data []byte, defaults *unversioned.GroupVersionKind, into Object) (Object, *unversioned.GroupVersionKind, error)
}

Decoders attempt to load an object from data.

type Encoder

type Encoder interface {
	// Encode writes an object to a stream. Implementations may return errors if the versions are
	// incompatible, or if no conversion is defined.
	Encode(obj Object, w io.Writer) error
}

Encoders write objects to a serialized form

type FieldLabelConversionFunc

type FieldLabelConversionFunc func(label, value string) (internalLabel, internalValue string, err error)

Function to convert a field selector to internal representation.

type Framer

type Framer interface {
	NewFrameReader(r io.ReadCloser) io.ReadCloser
	NewFrameWriter(w io.Writer) io.Writer
}

Framer is a factory for creating readers and writers that obey a particular framing pattern.

type GroupVersioner

type GroupVersioner interface {
	// KindForGroupVersionKinds returns a desired target group version kind for the given input, or returns ok false if no
	// target is known. In general, if the return target is not in the input list, the caller is expected to invoke
	// Scheme.New(target) and then perform a conversion between the current Go type and the destination Go type.
	// Sophisticated implementations may use additional information about the input kinds to pick a destination kind.
	KindForGroupVersionKinds(kinds []unversioned.GroupVersionKind) (target unversioned.GroupVersionKind, ok bool)
}

GroupVersioner refines a set of possible conversion targets into a single option.

var (
	// InternalGroupVersioner will always prefer the internal version for a given group version kind.
	InternalGroupVersioner GroupVersioner = internalGroupVersioner{}
	// DisabledGroupVersioner will reject all kinds passed to it.
	DisabledGroupVersioner GroupVersioner = disabledGroupVersioner{}
)

func NewMultiGroupVersioner

func NewMultiGroupVersioner(gv unversioned.GroupVersion, groupKinds ...unversioned.GroupKind) GroupVersioner

NewMultiGroupVersioner returns the provided group version for any kind that matches one of the provided group kinds. Kind may be empty in the provided group kind, in which case any kind will match.

type GroupVersioners

type GroupVersioners []GroupVersioner

GroupVersioners implements GroupVersioner and resolves to the first exact match for any kind.

func (GroupVersioners) KindForGroupVersionKinds

func (gvs GroupVersioners) KindForGroupVersionKinds(kinds []unversioned.GroupVersionKind) (unversioned.GroupVersionKind, bool)

KindForGroupVersionKinds returns the first match of any of the group versioners, or false if no match occured.

type KubeTypes

type KubeTypes []Pair

KubeTypes is an array to represent all available types in a parsed file. [0] is for the type itself

func ParseDocumentationFrom

func ParseDocumentationFrom(src string) []KubeTypes

ParseDocumentationFrom gets all types' documentation and returns them as an array. Each type is again represented as an array (we have to use arrays as we need to be sure for the order of the fields). This function returns fields and struct definitions that have no documentation as {name, ""}.

type MultiObjectTyper

type MultiObjectTyper []ObjectTyper

MultiObjectTyper returns the types of objects across multiple schemes in order.

func (MultiObjectTyper) ObjectKinds

func (MultiObjectTyper) Recognizes

type NegotiatedSerializer

type NegotiatedSerializer interface {
	// SupportedMediaTypes is the media types supported for reading and writing single objects.
	SupportedMediaTypes() []string
	// SerializerForMediaType returns a serializer for the provided media type. params is the set of
	// parameters applied to the media type that may modify the resulting output. ok will be false
	// if no serializer matched the media type.
	SerializerForMediaType(mediaType string, params map[string]string) (s SerializerInfo, ok bool)

	// SupportedStreamingMediaTypes returns the media types of the supported streaming serializers.
	// Streaming serializers control how multiple objects are written to a stream output.
	SupportedStreamingMediaTypes() []string
	// StreamingSerializerForMediaType returns a serializer for the provided media type that supports
	// reading and writing multiple objects to a stream. It returns a framer and serializer, or an
	// error if no such serializer can be created. Params is the set of parameters applied to the
	// media type that may modify the resulting output. ok will be false if no serializer matched
	// the media type.
	StreamingSerializerForMediaType(mediaType string, params map[string]string) (s StreamSerializerInfo, ok bool)

	// EncoderForVersion returns an encoder that ensures objects being written to the provided
	// serializer are in the provided group version.
	EncoderForVersion(serializer Encoder, gv GroupVersioner) Encoder
	// DecoderForVersion returns a decoder that ensures objects being read by the provided
	// serializer are in the provided group version by default.
	DecoderToVersion(serializer Decoder, gv GroupVersioner) Decoder
}

NegotiatedSerializer is an interface used for obtaining encoders, decoders, and serializers for multiple supported media types. This would commonly be accepted by a server component that performs HTTP content negotiation to accept multiple formats.

	DecodeNestedObjects(d Decoder) error
}

NestedObjectDecoder is an optional interface that objects may implement to be given an opportunity to decode any nested Objects / RawExtensions during serialization.

type NestedObjectEncoder

type NestedObjectEncoder interface {
	EncodeNestedObjects(e Encoder) error
}

NestedObjectEncoder is an optional interface that objects may implement to be given an opportunity to encode any nested Objects / RawExtensions during serialization.

type NoopDecoder

type NoopDecoder struct {
	Encoder
}

func (NoopEncoder) Encode

func (n NoopEncoder) Encode(obj Object, w io.Writer) error

type Object

type Object interface {
	GetObjectKind() unversioned.ObjectKind
}

All API types registered with Scheme must support the Object interface. Since objects in a scheme are expected to be serialized to the wire, the interface an Object must provide to the Scheme allows serializers to set the kind, version, and group the object is represented as. An Object may choose to return a no-op ObjectKindAccessor in cases where it is not expected to be serialized.

func Decode

func Decode(d Decoder, data []byte) (Object, error)

Decode is a convenience wrapper for decoding data into an Object.

func NewEncodable

func NewEncodable(e Encoder, obj Object, versions ...unversioned.GroupVersion) Object

NewEncodable creates an object that will be encoded with the provided codec on demand. Provided as a convenience for test cases dealing with internal objects.

func NewEncodableList

func NewEncodableList(e Encoder, objects []Object, versions ...unversioned.GroupVersion) []Object

NewEncodableList creates an object that will be encoded with the provided codec on demand. Provided as a convenience for test cases dealing with internal objects.

func UseOrCreateObject

func UseOrCreateObject(t ObjectTyper, c ObjectCreater, gvk unversioned.GroupVersionKind, obj Object) (Object, error)

UseOrCreateObject returns obj if the canonical ObjectKind returned by the provided typer matches gvk, or invokes the ObjectCreator to instantiate a new gvk. Returns an error if the typer cannot find the object.

type ObjectConvertor

type ObjectConvertor interface {
	// Convert attempts to convert one object into another, or returns an error. This method does
	// not guarantee the in object is not mutated. The context argument will be passed to
	// all nested conversions.
	Convert(in, out, context interface{}) error
	// ConvertToVersion takes the provided object and converts it the provided version. This
	// method does not guarantee that the in object is not mutated. This method is similar to
	// Convert() but handles specific details of choosing the correct output version.
	ConvertToVersion(in Object, gv GroupVersioner) (out Object, err error)
	ConvertFieldLabel(version, kind, label, value string) (string, string, error)
}

ObjectConvertor converts an object to a different version.

func UnsafeObjectConvertor

func UnsafeObjectConvertor(scheme *Scheme) ObjectConvertor

UnsafeObjectConvertor performs object conversion without copying the object structure, for use when the converted object will not be reused or mutated. Primarily for use within versioned codecs, which use the external object for serialization but do not return it.

type ObjectCopier

type ObjectCopier interface {
	// Copy returns an exact copy of the provided Object, or an error if the
	// copy could not be completed.
	Copy(Object) (Object, error)
}

ObjectCopier duplicates an object.

type ObjectCreater

type ObjectCreater interface {
	New(kind unversioned.GroupVersionKind) (out Object, err error)
}

ObjectCreater contains methods for instantiating an object by kind and version.

type ObjectTyper

type ObjectTyper interface {
	// ObjectKinds returns the all possible group,version,kind of the provided object, true if
	// the object is unversioned, or an error if the object is not recognized
	// (IsNotRegisteredError will return true).
	ObjectKinds(Object) ([]unversioned.GroupVersionKind, bool, error)
	// Recognizes returns true if the scheme is able to handle the provided version and kind,
	// or more precisely that the provided version is a possible conversion or decoding
	// target.
	Recognizes(gvk unversioned.GroupVersionKind) bool
}

ObjectTyper contains methods for extracting the APIVersion and Kind of objects.

type ObjectVersioner

type ObjectVersioner interface {
	ConvertToVersion(in Object, gv GroupVersioner) (out Object, err error)
}

type Pair

type Pair struct {
	Name, Doc string
}

Pair of strings. We keed the name of fields and the doc

type ParameterCodec

type ParameterCodec interface {
	// DecodeParameters takes the given url.Values in the specified group version and decodes them
	// into the provided object, or returns an error.
	DecodeParameters(parameters url.Values, from unversioned.GroupVersion, into Object) error
	// EncodeParameters encodes the provided object as query parameters or returns an error.
	EncodeParameters(obj Object, to unversioned.GroupVersion) (url.Values, error)
}

ParameterCodec defines methods for serializing and deserializing API objects to url.Values and performing any necessary conversion. Unlike the normal Codec, query parameters are not self describing and the desired version must be specified.

func NewParameterCodec

func NewParameterCodec(scheme *Scheme) ParameterCodec

NewParameterCodec creates a ParameterCodec capable of transforming url values into versioned objects and back.

type ProtobufMarshaller

type ProtobufMarshaller interface {
	MarshalTo(data []byte) (int, error)
}

type RawExtension

type RawExtension struct {
	// Raw is the underlying serialization of this object.
	//
	// TODO: Determine how to detect ContentType and ContentEncoding of 'Raw' data.
	Raw []byte `protobuf:"bytes,1,opt,name=raw"`
	// Object can hold a representation of this extension - useful for working with versioned
	// structs.
	Object Object `json:"-"`
}

RawExtension is used to hold extensions in external versions.

To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.

// Internal package: type MyAPIObject struct {

runtime.TypeMeta `json:",inline"`
MyPlugin runtime.Object `json:"myPlugin"`

} type PluginA struct {

AOption string `json:"aOption"`

}

// External package: type MyAPIObject struct {

runtime.TypeMeta `json:",inline"`
MyPlugin runtime.RawExtension `json:"myPlugin"`

} type PluginA struct {

AOption string `json:"aOption"`

}

// On the wire, the JSON will look something like this: {

"kind":"MyAPIObject",
"apiVersion":"v1",
"myPlugin": {
	"kind":"PluginA",
	"aOption":"foo",
},

}

So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)

type ResourceVersioner

type ResourceVersioner interface {
	SetResourceVersion(obj Object, version string) error
	ResourceVersion(obj Object) (string, error)
}

ResourceVersioner provides methods for setting and retrieving the resource version from an API object.

type Scheme

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

Scheme defines methods for serializing and deserializing API objects, a type registry for converting group, version, and kind information to and from Go schemas, and mappings between Go schemas of different versions. A scheme is the foundation for a versioned API and versioned configuration over time.

In a Scheme, a Type is a particular Go struct, a Version is a point-in-time identifier for a particular representation of that Type (typically backwards compatible), a Kind is the unique name for that Type within the Version, and a Group identifies a set of Versions, Kinds, and Types that evolve over time. An Unversioned Type is one that is not yet formally bound to a type and is promised to be backwards compatible (effectively a "v1" of a Type that does not expect to break in the future).

Schemes are not expected to change at runtime and are only threadsafe after registration is complete.

func NewScheme

func NewScheme() *Scheme

NewScheme creates a new Scheme. This scheme is pluggable by default.

func (*Scheme) AddConversionFuncs

func (s *Scheme) AddConversionFuncs(conversionFuncs ...interface{}) error

AddConversionFuncs adds functions to the list of conversion functions. The given functions should know how to convert between two of your API objects, or their sub-objects. We deduce how to call these functions from the types of their two parameters; see the comment for Converter.Register.

Note that, if you need to copy sub-objects that didn't change, you can use the conversion.Scope object that will be passed to your conversion function. Additionally, all conversions started by Scheme will set the SrcVersion and DestVersion fields on the Meta object. Example:

s.AddConversionFuncs(

func(in *InternalObject, out *ExternalObject, scope conversion.Scope) error {
	// You can depend on Meta() being non-nil, and this being set to
	// the source version, e.g., ""
	s.Meta().SrcVersion
	// You can depend on this being set to the destination version,
	// e.g., "v1".
	s.Meta().DestVersion
	// Call scope.Convert to copy sub-fields.
	s.Convert(&in.SubFieldThatMoved, &out.NewLocation.NewName, 0)
	return nil
},

)

(For more detail about conversion functions, see Converter.Register's comment.)

Also note that the default behavior, if you don't add a conversion function, is to sanely copy fields that have the same names and same type names. It's OK if the destination type has extra fields, but it must not remove any. So you only need to add conversion functions for things with changed/removed fields.

func (*Scheme) AddDeepCopyFuncs

func (s *Scheme) AddDeepCopyFuncs(deepCopyFuncs ...interface{}) error

AddDeepCopyFuncs adds a function to the list of deep-copy functions. For the expected format of deep-copy function, see the comment for Copier.RegisterDeepCopyFunction.

func (*Scheme) AddDefaultingFuncs

func (s *Scheme) AddDefaultingFuncs(defaultingFuncs ...interface{}) error

AddDefaultingFuncs adds functions to the list of default-value functions. Each of the given functions is responsible for applying default values when converting an instance of a versioned API object into an internal API object. These functions do not need to handle sub-objects. We deduce how to call these functions from the types of their two parameters.

s.AddDefaultingFuncs(

func(obj *v1.Pod) {
	if obj.OptionalField == "" {
		obj.OptionalField = "DefaultValue"
	}
},

)

func (*Scheme) AddFieldLabelConversionFunc

func (s *Scheme) AddFieldLabelConversionFunc(version, kind string, conversionFunc FieldLabelConversionFunc) error

AddFieldLabelConversionFunc adds a conversion function to convert field selectors of the given kind from the given version to internal version representation.

func (*Scheme) AddGeneratedConversionFuncs

func (s *Scheme) AddGeneratedConversionFuncs(conversionFuncs ...interface{}) error

Similar to AddConversionFuncs, but registers conversion functions that were automatically generated.

func (*Scheme) AddGeneratedDeepCopyFuncs

func (s *Scheme) AddGeneratedDeepCopyFuncs(deepCopyFuncs ...conversion.GeneratedDeepCopyFunc) error

Similar to AddDeepCopyFuncs, but registers deep-copy functions that were automatically generated.

func (*Scheme) AddGenericConversionFunc

func (s *Scheme) AddGenericConversionFunc(fn conversion.GenericConversionFunc)

AddGenericConversionFunc adds a function that accepts the ConversionFunc call pattern (for two conversion types) to the converter. These functions are checked first during a normal conversion, but are otherwise not called. Use AddConversionFuncs when registering typed conversions.

func (*Scheme) AddIgnoredConversionType

func (s *Scheme) AddIgnoredConversionType(from, to interface{}) error

AddIgnoredConversionType identifies a pair of types that should be skipped by conversion (because the data inside them is explicitly dropped during conversion).

func (*Scheme) AddKnownTypeWithName

func (s *Scheme) AddKnownTypeWithName(gvk unversioned.GroupVersionKind, obj Object)

AddKnownTypeWithName is like AddKnownTypes, but it lets you specify what this type should be encoded as. Useful for testing when you don't want to make multiple packages to define your structs. Version may not be empty - use the APIVersionInternal constant if you have a type that does not have a formal version.

func (*Scheme) AddKnownTypes

func (s *Scheme) AddKnownTypes(gv unversioned.GroupVersion, types ...Object)

AddKnownTypes registers all types passed in 'types' as being members of version 'version'. All objects passed to types should be pointers to structs. The name that go reports for the struct becomes the "kind" field when encoding. Version may not be empty - use the APIVersionInternal constant if you have a type that does not have a formal version.

func (*Scheme) AddStructFieldConversion

func (s *Scheme) AddStructFieldConversion(srcFieldType interface{}, srcFieldName string, destFieldType interface{}, destFieldName string) error

AddStructFieldConversion allows you to specify a mechanical copy for a moved or renamed struct field without writing an entire conversion function. See the comment in conversion.Converter.SetStructFieldCopy for parameter details. Call as many times as needed, even on the same fields.

func (*Scheme) AddUnversionedTypes

func (s *Scheme) AddUnversionedTypes(version unversioned.GroupVersion, types ...Object)

AddUnversionedTypes registers the provided types as "unversioned", which means that they follow special rules. Whenever an object of this type is serialized, it is serialized with the provided group version and is not converted. Thus unversioned objects are expected to remain backwards compatible forever, as if they were in an API group and version that would never be updated.

TODO: there is discussion about removing unversioned and replacing it with objects that are manifest into

every version with particular schemas. Resolve this method at that point.

func (*Scheme) AllKnownTypes

func (s *Scheme) AllKnownTypes() map[unversioned.GroupVersionKind]reflect.Type

AllKnownTypes returns the all known types.

func (*Scheme) Convert

func (s *Scheme) Convert(in, out interface{}, context interface{}) error

Convert will attempt to convert in into out. Both must be pointers. For easy testing of conversion functions. Returns an error if the conversion isn't possible. You can call this with types that haven't been registered (for example, a to test conversion of types that are nested within registered types). The context interface is passed to the convertor. TODO: identify whether context should be hidden, or behind a formal context/scope

interface

func (*Scheme) ConvertFieldLabel

func (s *Scheme) ConvertFieldLabel(version, kind, label, value string) (string, string, error)

Converts the given field label and value for an kind field selector from versioned representation to an unversioned one.

func (*Scheme) ConvertToVersion

func (s *Scheme) ConvertToVersion(in Object, target GroupVersioner) (Object, error)

ConvertToVersion attempts to convert an input object to its matching Kind in another version within this scheme. Will return an error if the provided version does not contain the inKind (or a mapping by name defined with AddKnownTypeWithName). Will also return an error if the conversion does not result in a valid Object being returned. Passes target down to the conversion methods as the Context on the scope.

func (*Scheme) Converter

func (*Scheme) ObjectKind

func (s *Scheme) ObjectKind(obj Object) (unversioned.GroupVersionKind, bool, error)

ObjectKind returns the group,version,kind of the go object and true if this object is considered unversioned, or an error if it's not a pointer or is unregistered.

func (*Scheme) ObjectKinds

func (s *Scheme) ObjectKinds(obj Object) ([]unversioned.GroupVersionKind, bool, error)

ObjectKinds returns all possible group,version,kind of the go object, true if the object is considered unversioned, or an error if it's not a pointer or is unregistered.

func (*Scheme) Recognizes

func (s *Scheme) Recognizes(gvk unversioned.GroupVersionKind) bool

Recognizes returns true if the scheme is able to handle the provided group,version,kind of an object.

func (*Scheme) RegisterInputDefaults

func (s *Scheme) RegisterInputDefaults(in interface{}, fn conversion.FieldMappingFunc, defaultFlags conversion.FieldMatchingFlags) error

RegisterInputDefaults sets the provided field mapping function and field matching as the defaults for the provided input type. The fn may be nil, in which case no mapping will happen by default. Use this method to register a mechanism for handling a specific input type in conversion, such as a map[string]string to structs.

func (*Scheme) UnsafeConvertToVersion

func (s *Scheme) UnsafeConvertToVersion(in Object, target GroupVersioner) (Object, error)

UnsafeConvertToVersion will convert in to the provided target if such a conversion is possible, but does not guarantee the output object does not share fields with the input object. It attempts to be as efficient as possible when doing conversion.

type SchemeBuilder

type SchemeBuilder []func(*Scheme) error

SchemeBuilder collects functions that add things to a scheme. It's to allow code to compile without explicitly referencing generated types. You should declare one in each package that will have generated deep copy or conversion functions.

func NewSchemeBuilder

func NewSchemeBuilder(funcs ...func(*Scheme) error) SchemeBuilder

NewSchemeBuilder calls Register for you.

func (*SchemeBuilder) AddToScheme

func (sb *SchemeBuilder) AddToScheme(s *Scheme) error

AddToScheme applies all the stored functions to the scheme. A non-nil error indicates that one function failed and the attempt was abandoned.

func (*SchemeBuilder) Register

func (sb *SchemeBuilder) Register(funcs ...func(*Scheme) error)

Register adds a scheme setup function to the list.

type SelfLinker

type SelfLinker interface {
	SetSelfLink(obj Object, selfLink string) error
	SelfLink(obj Object) (string, error)

	// Knowing Name is sometimes necessary to use a SelfLinker.
	Name(obj Object) (string, error)
	// Knowing Namespace is sometimes necessary to use a SelfLinker
	Namespace(obj Object) (string, error)
}

SelfLinker provides methods for setting and retrieving the SelfLink field of an API object.

type Serializer

type Serializer interface {
	Encoder
	Decoder
}

Serializer is the core interface for transforming objects into a serialized format and back. Implementations may choose to perform conversion of the object, but no assumptions should be made.

func NewBase64Serializer

func NewBase64Serializer(s Serializer) Serializer

type SerializerInfo

type SerializerInfo struct {
	Serializer
	// EncodesAsText indicates this serializer can be encoded to UTF-8 safely.
	EncodesAsText bool
	// MediaType is the value that represents this serializer over the wire.
	MediaType string
}

SerializerInfo contains information about a specific serialization format

type StorageSerializer

type StorageSerializer interface {
	// SerializerForMediaType returns a serializer for the provided media type.  Options is a set of
	// parameters applied to the media type that may modify the resulting output.
	SerializerForMediaType(mediaType string, options map[string]string) (SerializerInfo, bool)

	// UniversalDeserializer returns a Serializer that can read objects in multiple supported formats
	// by introspecting the data at rest.
	UniversalDeserializer() Decoder

	// EncoderForVersion returns an encoder that ensures objects being written to the provided
	// serializer are in the provided group version.
	EncoderForVersion(serializer Encoder, gv GroupVersioner) Encoder
	// DecoderForVersion returns a decoder that ensures objects being read by the provided
	// serializer are in the provided group version by default.
	DecoderToVersion(serializer Decoder, gv GroupVersioner) Decoder
}

StorageSerializer is an interface used for obtaining encoders, decoders, and serializers that can read and write data at rest. This would commonly be used by client tools that must read files, or server side storage interfaces that persist restful objects.

type StreamSerializerInfo

type StreamSerializerInfo struct {
	SerializerInfo
	// Framer is the factory for retrieving streams that separate objects on the wire
	Framer
	// Embedded is the type of the nested serialization that should be used.
	Embedded SerializerInfo
}

StreamSerializerInfo contains information about a specific stream serialization format

type TypeMeta

type TypeMeta struct {

	Kind       string `json:"kind,omitempty" yaml:"kind,omitempty" protobuf:"bytes,2,opt,name=kind"`
}

TypeMeta is shared by all top level objects. The proper way to use it is to inline it in your type, like this: type MyAwesomeAPIObject struct {

runtime.TypeMeta    `json:",inline"`
... // other fields

} func (obj *MyAwesomeAPIObject) SetGroupVersionKind(gvk *unversioned.GroupVersionKind) { unversioned.UpdateTypeMeta(obj,gvk) }; GroupVersionKind() *GroupVersionKind

TypeMeta is provided here for convenience. You may use it directly from this package or define your own with the same fields.

type Unknown

type Unknown struct {
	TypeMeta `json:",inline" protobuf:"bytes,1,opt,name=typeMeta"`
	// Raw will hold the complete serialized object which couldn't be matched
	// with a registered type. Most likely, nothing should be done with this
	// except for passing it through the system.
	Raw []byte `protobuf:"bytes,2,opt,name=raw"`
	// ContentEncoding is encoding used to encode 'Raw' data.
	// Unspecified means no encoding.
	ContentEncoding string `protobuf:"bytes,3,opt,name=contentEncoding"`
	// ContentType  is serialization method used to serialize 'Raw'.
	// Unspecified means ContentTypeJSON.
	ContentType string `protobuf:"bytes,4,opt,name=contentType"`
}

Unknown allows api objects with unknown types to be passed-through. This can be used to deal with the API objects from a plug-in. Unknown objects still have functioning TypeMeta features-- kind, version, etc. TODO: Make this object have easy access to field based accessors and settors for metadata and field mutatation.

	// other objects may be present. The right most object is the same as would be returned
	// by a normal Decode call.
	Objects []Object
}

VersionedObjects is used by Decoders to give callers a way to access all versions of an object during the decoding process.
