Functions

func DeleteNullInJson 

func DeleteNullInJson(jsonBytes []byte) ([]byte, map[string]interface{}, error)

Types

type Annotator 

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

func NewAnnotator 

func NewAnnotator(key string) *Annotator

func (*Annotator) GetModifiedConfiguration 

func (a *Annotator) GetModifiedConfiguration(obj runtime.Object, annotate bool) ([]byte, error)

GetModifiedConfiguration retrieves the modified configuration of the object. If annotate is true, it embeds the result as an annotation in the modified configuration. If an object was read from the command input, it will use that version of the object. Otherwise, it will use the version from the server.

func (*Annotator) GetOriginalConfiguration 

func (a *Annotator) GetOriginalConfiguration(obj runtime.Object) ([]byte, error)

GetOriginalConfiguration retrieves the original configuration of the object from the annotation, or nil if no annotation was found.

func (*Annotator) SetLastAppliedAnnotation 

func (a *Annotator) SetLastAppliedAnnotation(obj runtime.Object) error

SetLastAppliedAnnotation gets the modified configuration of the object, without embedding it again, and then sets it on the object as the annotation.

func (*Annotator) SetOriginalConfiguration 

func (a *Annotator) SetOriginalConfiguration(obj runtime.Object, original []byte) error

SetOriginalConfiguration sets the original configuration of the object as the annotation on the object for later use in computing a three way patch.
