Functions

func CreateDeleteDirective added in v1.7.1 

func CreateDeleteDirective(mergeKey string, mergeKeyValue interface{}) map[string]interface{}

func CreateThreeWayMergePatch 

func CreateThreeWayMergePatch(original, modified, current []byte, schema LookupPatchMeta, overwrite bool, fns ...mergepatch.PreconditionFunc) ([]byte, error)

CreateThreeWayMergePatch reconciles a modified configuration with an original configuration, while preserving any changes or deletions made to the original configuration in the interim, and not overridden by the current configuration. All three documents must be passed to the method as json encoded content. It will return a strategic merge patch, or an error if any of the documents is invalid, or if there are any preconditions that fail against the modified configuration, or, if overwrite is false and there are conflicts between the modified and current configurations. Conflicts are defined as keys changed differently from original to modified than from original to current. In other words, a conflict occurs if modified changes any key in a way that is different from how it is changed in current (e.g., deleting it, changing its value). We also propagate values fields that do not exist in original but are explicitly defined in modified.

func CreateTwoWayMergePatch 

func CreateTwoWayMergePatch(original, modified []byte, dataStruct interface{}, fns ...mergepatch.PreconditionFunc) ([]byte, error)

CreateTwoWayMergePatch creates a patch that can be passed to StrategicMergePatch from an original document and a modified document, which are passed to the method as json encoded content. It will return a patch that yields the modified document when applied to the original document, or an error if either of the two documents is invalid.

func CreateTwoWayMergePatchUsingLookupPatchMeta added in v1.9.1 

func CreateTwoWayMergePatchUsingLookupPatchMeta(
	original, modified []byte, schema LookupPatchMeta, fns ...mergepatch.PreconditionFunc) ([]byte, error)

func GetTagStructTypeOrDie added in v1.9.1 

func GetTagStructTypeOrDie(dataStruct interface{}) reflect.Type

func ItemAddedToModifiedSlice added in v1.7.1 

func ItemAddedToModifiedSlice(original, modified string) bool

func ItemMatchesOriginalAndModifiedSlice added in v1.7.1 

func ItemMatchesOriginalAndModifiedSlice(original, modified string) bool

func ItemRemovedFromModifiedSlice added in v1.7.1 

func ItemRemovedFromModifiedSlice(original, modified string) bool

func MergingMapsHaveConflicts 

func MergingMapsHaveConflicts(left, right map[string]interface{}, schema LookupPatchMeta) (bool, error)

MergingMapsHaveConflicts returns true if the left and right JSON interface objects overlap with different values in any key. All keys are required to be strings. Since patches of the same Type have congruent keys, this is valid for multiple patch types. This method supports strategic merge patch semantics.

func NewKindItem added in v1.9.1 

func NewKindItem(key string, path *openapi.Path) *kindItem

func NewSliceItem added in v1.9.1 

func NewSliceItem(key string, path *openapi.Path) *sliceItem

func StrategicMergePatch 

func StrategicMergePatch(original, patch []byte, dataStruct interface{}) ([]byte, error)

StrategicMergePatch applies a strategic merge patch. The patch and the original document must be json encoded content. A patch can be created from an original and a modified document by calling CreateStrategicMergePatch.

func StrategicMergePatchUsingLookupPatchMeta added in v1.9.1 

func StrategicMergePatchUsingLookupPatchMeta(original, patch []byte, schema LookupPatchMeta) ([]byte, error)

Types

type DiffOptions added in v1.7.1 

type DiffOptions struct {
	// SetElementOrder determines whether we generate the $setElementOrder parallel list.
	SetElementOrder bool
	// IgnoreChangesAndAdditions indicates if we keep the changes and additions in the patch.
	IgnoreChangesAndAdditions bool
	// IgnoreDeletions indicates if we keep the deletions in the patch.
	IgnoreDeletions bool
	// We introduce a new value retainKeys for patchStrategy.
	// It indicates that all fields needing to be preserved must be
	// present in the `retainKeys` list.
	// And the fields that are present will be merged with live object.
	// All the missing fields will be cleared when patching.
	BuildRetainKeysDirective bool
}

type FieldNotFoundError added in v1.9.1 

type FieldNotFoundError struct {
	Path  string
	Field string
}

func (FieldNotFoundError) Error added in v1.9.1 

func (e FieldNotFoundError) Error() string

type InvalidTypeError added in v1.9.1 

type InvalidTypeError struct {
	Path     string
	Expected string
	Actual   string
}

func (InvalidTypeError) Error added in v1.9.1 

func (e InvalidTypeError) Error() string

type JSONMap 

type JSONMap map[string]interface{}

JSONMap is a representations of JSON object encoded as map[string]interface{} where the children can be either map[string]interface{}, []interface{} or primitive type). Operating on JSONMap representation is much faster as it doesn't require any json marshaling and/or unmarshaling operations.

func CreateTwoWayMergeMapPatch 

func CreateTwoWayMergeMapPatch(original, modified JSONMap, dataStruct interface{}, fns ...mergepatch.PreconditionFunc) (JSONMap, error)

CreateTwoWayMergeMapPatch creates a patch from an original and modified JSON objects, encoded JSONMap. The serialized version of the map can then be passed to StrategicMergeMapPatch.

func CreateTwoWayMergeMapPatchUsingLookupPatchMeta added in v1.9.1 

func CreateTwoWayMergeMapPatchUsingLookupPatchMeta(original, modified JSONMap, schema LookupPatchMeta, fns ...mergepatch.PreconditionFunc) (JSONMap, error)

func StrategicMergeMapPatch 

func StrategicMergeMapPatch(original, patch JSONMap, dataStruct interface{}) (JSONMap, error)

StrategicMergeMapPatch applies a strategic merge patch. The original and patch documents must be JSONMap. A patch can be created from an original and modified document by calling CreateTwoWayMergeMapPatch. Warning: the original and patch JSONMap objects are mutated by this function and should not be reused.
