func ConvertAndSetList ¶

func ConvertAndSetList(scheme *runtime.Scheme, list runtime.Object, objs []runtime.Object) error

ConvertAndSetList converts the given runtime.Objects into the item type of the list and sets the list items to be the converted items.

func ExtractList ¶ added in v0.3.5

func ExtractList(obj client.ObjectList) ([]client.Object, error)

ExtractList extracts the items of a list into a slice of client.Object.

func ExtractObjectSlice ¶ added in v0.3.5

func ExtractObjectSlice(slice interface{}) ([]client.Object, error)

ExtractObjectSlice extracts client.Object from a given slice.

func ExtractObjectSlicePointer ¶ added in v0.3.5

func ExtractObjectSlicePointer(slicePtr interface{}) ([]client.Object, error)

func FilterControlledBy ¶ added in v0.3.5

func FilterControlledBy(scheme *runtime.Scheme, owner client.Object, objects []client.Object) ([]client.Object, error)

FilterControlledBy filters multiple objects by using IsControlledBy on each item.

func GVKForList ¶

func GVKForList(scheme *runtime.Scheme, list runtime.Object) (schema.GroupVersionKind, error)

GVKForList determines the schema.GroupVersionKind for the given list. Effectively, this strips a 'List' suffix from the kind, if it exists.

func IsControlledBy ¶ added in v0.3.3

func IsControlledBy(scheme *runtime.Scheme, owner, controlled client.Object) (bool, error)

IsControlledBy checks if controlled is controlled by owner. An object is considered to be controlled if there is a controller (via metav1.GetControllerOf) whose GVK, name and UID match with the controller object.

func ListElementType ¶

func ListElementType(list runtime.Object) (reflect.Type, error)

ListElementType returns the element type of the list. For instance, for an appsv1.DeploymentList, the element type is appsv1.Deployment.

func SetList ¶ added in v0.3.5

func SetList(list client.ObjectList, objects []client.Object) error

SetList sets the items in a client.ObjectList to the given objects.

func SetObjectSlice ¶ added in v0.3.5

func SetObjectSlice(slicePtr interface{}, objects []client.Object) error

SetObjectSlice sets a slice pointer's values to the given objects.
