Modifier and Type Field Description

static PayloadDecoder FLOAT_DECODER
A PayloadDecoder that interprets the bytes of a payload as a float

Method Summary

All Methods Instance Methods Abstract Methods Default Methods Deprecated Methods
Modifier and Type	Method	Description
`default float`	`computePayloadFactor(int docID, int startPosition, int endPosition, BytesRef payload)`	Deprecated. Use `computePayloadFactor(BytesRef)` - doc and position can be taken into account in `PayloadFunction.currentScore(int, String, int, int, int, float, float)`
`float`	`computePayloadFactor(BytesRef payload)`	Compute a float value for the given payload
