Overview

Package latest defines the default output serializations that code should use and imports the required schemas. It also ensures all previously known and supported API versions are available for conversion. Consumers may import this package in lieu of importing individual versions.

	// It equals to the "version" part of GroupVersion.
	Version string

	// Group represents the name of the group
	Group string

	// Versions is the list of versions that are recognized in code. The order
	// provided is assumed to be from the oldest to the newest, e.g.,
	// Versions[0] == oldest and Versions[N-1] == newest.
	// Clients may choose to prefer the latter items in the list over the former
	// items when presented with a set of versions to choose.

	// in many places.

	// Codec is the default codec for serializing output that should use
	// the latest supported version.  Use this Codec when writing to

	// This codec can decode any object that Kubernetes is aware of.
	Codec runtime.Codec

	// Kubernetes versions.

GroupMeta stores the metadata of a group, such as the latest supported version.

type GroupMetaMap

type GroupMetaMap map[string]*GroupMeta

GroupMetaMap is a map between group names and their metadata.

func (GroupMetaMap) AllPreferredGroupVersions

func (g GroupMetaMap) AllPreferredGroupVersions() string

AllPreferredGroupVersions returns the preferred versions of all registered groups in the form of "group1/version1,group2/version2,..."

func (GroupMetaMap) Group

func (g GroupMetaMap) Group(group string) (*GroupMeta, error)

Group returns the metadata of a group if the gruop is registered, otherwise an erorr is returned.

func (GroupMetaMap) GroupOrDie

func (g GroupMetaMap) GroupOrDie(group string) *GroupMeta

TODO: This is an expedient function, because we don't check if a Group is supported throughout the code base. We will abandon this function and checking the error returned by the Group() function.

func (GroupMetaMap) RegisterGroup

func (g GroupMetaMap) RegisterGroup(group string) (*GroupMeta, error)

RegisterGroup registers a group to GroupMetaMap.
