Types

type BaseGenerator

type BaseGenerator struct {
}

BaseGenerator contains settings specific for Influx database.

func (*BaseGenerator) GenerateEmptyQuery

func (g *BaseGenerator) GenerateEmptyQuery() query.Query

GenerateEmptyQuery returns an empty query.HTTP.

func (*BaseGenerator) NewIoT

func (g *BaseGenerator) NewIoT(start, end time.Time, scale int) (utils.QueryGenerator, error)

NewIoT creates a new iot use case query generator.

type IoT

type IoT struct {
	*iot.Core
	*BaseGenerator
}

IoT produces Influx-specific queries for all the iot query types.

func NewIoT

func NewIoT(start, end time.Time, scale int, g *BaseGenerator) *IoT

NewIoT makes an IoT object ready to generate Queries.
