Types

type Indexer

type Indexer struct {
	*badger.DB
}

func (*Indexer) Begin

func (idx *Indexer) Begin() storage.Tx

func (*Indexer) Get

func (idx *Indexer) Get(k string) (*storage.DataPoint, error)

Get the most recent entry for k

func (*Indexer) GetAll

func (idx *Indexer) GetAll(k string, count int) ([]storage.DataPoint, error)

GetAll return all entries for k up to count

func (*Indexer) Keys

func (idx *Indexer) Keys() ([]string, error)

Keys list all keys

func (*Indexer) RadiusSearch

func (idx *Indexer) RadiusSearch(lat, lng, radius float64) ([]storage.DataPoint, error)

RadiusSearch returns the Points found in the index inside radius (no data)

func (*Indexer) RectSearch
