Types

type Longs

type Longs []int64

func (Longs) Len

func (a Longs) Len() int

func (Longs) Less

func (a Longs) Less(i, j int) bool

func (Longs) Swap

func (a Longs) Swap(i, j int)

type Lucene49Codec

type Lucene49Codec struct {
	*CodecImpl
}

Implements the Lucene 4.9 index format, with configurable per-field postings and docvalues formats.

If you want to reuse functionality of this codec in another codec, extend FilterCodec.

type Lucene49NormsFormat

type Lucene49NormsFormat struct {
}

func (*Lucene49NormsFormat) NormsConsumer

func (f *Lucene49NormsFormat) NormsConsumer(state *SegmentWriteState) (w DocValuesConsumer, err error)

func (*Lucene49NormsFormat) NormsProducer

type NormMap

type NormMap struct {
	// contains filtered or unexported fields
}
