示例3: Equal

// Equal returns true iff the two keys represent identical key values.
func Equal(a, b ds.Key) (ret bool) {
	ret = (a.Kind() == b.Kind() &&
		a.StringID() == b.StringID() &&
		a.IntID() == b.IntID() &&
		a.AppID() == b.AppID() &&
		a.Namespace() == b.Namespace())
	if !ret {
		return
	}
	ap, bp := a.Parent(), b.Parent()
	return (ap == nil && bp == nil) || Equal(ap, bp)
}

func (d *dataStoreData) allocateIDsLocked(ents *memCollection, incomplete *ds.Key, n int) (int64, error) {
	if d.disableSpecialEntities {
		return 0, errors.New("disableSpecialEntities is true so allocateIDs is disabled")
	}

	idKey := []byte(nil)

示例7: Valid

// Valid determines if a key is valid, according to a couple rules:
//   - k is not nil
//   - every token of k:
//     - (if !allowSpecial) token's kind doesn't start with '__'
//     - token's kind and appid are non-blank
//     - token is not incomplete
//   - all tokens have the same namespace and appid
func Valid(k ds.Key, allowSpecial bool, aid, ns string) bool {
	if k == nil {
		return false
	}
	if aid != k.AppID() || ns != k.Namespace() {
		return false
	}
	for ; k != nil; k = k.Parent() {
		if !allowSpecial && len(k.Kind()) >= 2 && k.Kind()[:2] == "__" {
			return false
		}
		if k.Kind() == "" || k.AppID() == "" {
			return false
		}
		if k.StringID() != "" && k.IntID() != 0 {
			return false
		}
		if k.Parent() != nil {
			if k.Parent().Incomplete() {
				return false
			}
			if k.Parent().AppID() != k.AppID() || k.Parent().Namespace() != k.Namespace() {
				return false
			}
		}
	}
	return true

示例8: indexEntriesWithBuiltins

func indexEntriesWithBuiltins(k ds.Key, pm ds.PropertyMap, complexIdxs []*ds.IndexDefinition) *memStore {
	sip := partiallySerialize(k, pm)
	return sip.indexEntries(k.Namespace(), append(defaultIndexes(k.Kind(), pm), complexIdxs...))
}

示例9: PartialValid

// PartialValid returns true iff this key is suitable for use in a Put
// operation. This is the same as Valid(k, false, ...), but also allowing k to
// be Incomplete().
func PartialValid(k ds.Key, aid, ns string) bool {
	if k.Incomplete() {
		k = New(k.AppID(), k.Namespace(), k.Kind(), "", 1, k.Parent())
	}
	return Valid(k, false, aid, ns)
