func GetNoneSelector ¶

func GetNoneSelector(inst *unstructured.Unstructured) (bool, error)

func GetSelector ¶

func GetSelector(inst *unstructured.Unstructured) (labels.Selector, error)

GetSelector returns the selector on a given object if it exists

func GetSelectorAnnotation ¶

func GetSelectorAnnotation(inst *unstructured.Unstructured) string

func GetTreeSelector ¶

func GetTreeSelector(inst *unstructured.Unstructured) (labels.Selector, error)

GetTreeSelector is similar to a regular selector, except that it adds the LabelTreeDepthSuffix to every string To transform a tree selector into a regular label selector, we follow these steps: 1. get the treeSelector annotation if it exists 2. convert the annotation string to a slice of strings seperated by comma, because user is allowed to put multiple selectors 3. append the LabelTreeDepthSuffix to each of the treeSelector string 4. combine them into a single string connected by comma

func GetTreeSelectorAnnotation ¶

func GetTreeSelectorAnnotation(inst *unstructured.Unstructured) string

func ShouldPropagate ¶
