Golang Bucket.Writable Examples

Example #1

File: unique.go Project: asdine/storm

// NewUniqueIndex loads a UniqueIndex
func NewUniqueIndex(parent *bolt.Bucket, indexName []byte) (*UniqueIndex, error) {
	var err error
	b := parent.Bucket(indexName)
	if b == nil {
		if !parent.Writable() {
			return nil, ErrNotFound
		}
		b, err = parent.CreateBucket(indexName)
		if err != nil {
			return nil, err
		}
	}

	return &UniqueIndex{
		IndexBucket: b,
		Parent:      parent,
	}, nil
}

Example #2

File: list.go Project: asdine/storm

// NewListIndex loads a ListIndex
func NewListIndex(parent *bolt.Bucket, indexName []byte) (*ListIndex, error) {
	var err error
	b := parent.Bucket(indexName)
	if b == nil {
		if !parent.Writable() {
			return nil, ErrNotFound
		}
		b, err = parent.CreateBucket(indexName)
		if err != nil {
			return nil, err
		}
	}

	ids, err := NewUniqueIndex(b, []byte("storm__ids"))
	if err != nil {
		return nil, err
	}

	return &ListIndex{
		IndexBucket: b,
		Parent:      parent,
		IDs:         ids,
	}, nil
}
