Overview ¶

Package boltdb provides a pdk.Translator implementation using boltdb. BoltDB is great, but this package is not particularly well-used or tested, and it is recommended that one use the leveldb translator instead which has better write performance.

Index ¶

type Translator
- func NewTranslator(filename string, fields ...string) (bt *Translator, err error)

Types ¶

type Translator ¶

type Translator struct {
	Db *bolt.DB
	// contains filtered or unexported fields
}

Translator is a pdk.Translator which stores the two way val/id mapping in boltdb. It only accepts string values to map.

func NewTranslator ¶

func NewTranslator(filename string, fields ...string) (bt *Translator, err error)

NewTranslator gets a new Translator

func (*Translator) BulkAdd ¶

func (bt *Translator) BulkAdd(field string, values [][]byte) error

BulkAdd adds many values to a field at once, allocating ids.

func (*Translator) Close ¶

func (bt *Translator) Close() error

Close syncs and closes the underlying boltdb.

func (*Translator) Get ¶

func (bt *Translator) Get(field string, id uint64) (val interface{})

Get returns the previously mapped value to the monotonic id generated from GetID. For BoltTranslator, val will always be a []byte.

func (*Translator) GetID ¶

func (bt *Translator) GetID(field string, val interface{}) (id uint64, err error)

GetID maps val (which must be a byte slice) to a monotonic id.
