Functions

func GetObjectGroupKind

func GetObjectGroupKind(obj runtime.Object) schema.GroupKind

func IsInternalObjectError

func IsInternalObjectError(err error) bool

Types

type JSONPrinter

type JSONPrinter struct{}

JSONPrinter is an implementation of ResourcePrinter which outputs an object as JSON.

func (*JSONPrinter) PrintObj

func (p *JSONPrinter) PrintObj(obj runtime.Object, w io.Writer) error

PrintObj is an implementation of ResourcePrinter.PrintObj which simply writes the object to the Writer.

type NamePrinter

type NamePrinter struct {
	// ShortOutput indicates whether an operation should be
	// printed along side the "resource/name" pair for an object.
	ShortOutput bool
	// Operation describes the name of the action that
	// took place on an object, to be included in the
	// finalized "successful" message.
	Operation string
}

NamePrinter is an implementation of ResourcePrinter which outputs "resource/name" pair of an object.

func (*NamePrinter) PrintObj

func (p *NamePrinter) PrintObj(obj runtime.Object, w io.Writer) error

PrintObj is an implementation of ResourcePrinter.PrintObj which decodes the object and print "resource/name" pair. If the object is a List, print all items in it.

type ResourcePrinter

type ResourcePrinter interface {
	// Print receives a runtime object, formats it and prints it to a writer.
	PrintObj(runtime.Object, io.Writer) error
}

ResourcePrinter is an interface that knows how to print runtime objects.

type ResourcePrinterFunc

type ResourcePrinterFunc func(runtime.Object, io.Writer) error

ResourcePrinterFunc is a function that can print objects

func NewDiscardingPrinter

func NewDiscardingPrinter() ResourcePrinterFunc

NewDiscardingPrinter is a printer that discards all objects

func (ResourcePrinterFunc) PrintObj

func (fn ResourcePrinterFunc) PrintObj(obj runtime.Object, w io.Writer) error

PrintObj implements ResourcePrinter

type TypeSetterPrinter

type TypeSetterPrinter struct {
	Delegate ResourcePrinter

	Typer runtime.ObjectTyper
}

TypeSetterPrinter is an implementation of ResourcePrinter wraps another printer with types set on the objects

func NewTypeSetter

func NewTypeSetter(typer runtime.ObjectTyper) *TypeSetterPrinter

NewTypeSetter constructs a wrapping printer with required params

func (*TypeSetterPrinter) PrintObj

func (p *TypeSetterPrinter) PrintObj(obj runtime.Object, w io.Writer) error

PrintObj is an implementation of ResourcePrinter.PrintObj which sets type information on the obj for the duration of printing. It is NOT threadsafe.

func (*TypeSetterPrinter) ToPrinter

func (p *TypeSetterPrinter) ToPrinter(delegate ResourcePrinter) ResourcePrinter

ToPrinter returns a printer (not threadsafe!) that has been wrapped

func (*TypeSetterPrinter) WrapToPrinter

func (p *TypeSetterPrinter) WrapToPrinter(delegate ResourcePrinter, err error) (ResourcePrinter, error)

WrapToPrinter wraps the common ToPrinter method

type YAMLPrinter

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

YAMLPrinter is an implementation of ResourcePrinter which outputs an object as YAML. The input object is assumed to be in the internal version of an API and is converted to the given version first.

func (*YAMLPrinter) PrintObj

func (p *YAMLPrinter) PrintObj(obj runtime.Object, w io.Writer) error

PrintObj prints the data as YAML.
