Types

type Gap

type Gap struct {
	uda.AggInterface

	BigGapIdxs []int
	Input      *io.ColumnInterface
	// contains filtered or unexported fields
}

func NewGap

func NewGap() (g *Gap)

CONCRETE - these may be suitable methods for general usage

func (*Gap) Accum

func (g *Gap) Accum(_ io.TimeBucketKey, _ *functions.ArgumentMap,
	cols io.ColumnInterface, _ *catalog.Directory,
) error

Accum() sends new data to the aggregate Use Zscore to find out the big hole in data.

func (*Gap) GetInitArgs

func (g *Gap) GetInitArgs() []io.DataShape

func (*Gap) GetOptionalArgs

func (g *Gap) GetOptionalArgs() []io.DataShape

func (*Gap) GetRequiredArgs

func (g *Gap) GetRequiredArgs() []io.DataShape

func (*Gap) Init

func (g *Gap) Init(_ *functions.ArgumentMap, args ...interface{}) error

func (Gap) New

func (g Gap) New() (out uda.AggInterface)

Creates a new count using the arguments of the specific implementation for inputColumns and optionalInputColumns

func (*Gap) Output

func (g *Gap) Output() *io.ColumnSeries

Output() returns the currently valid output of this aggregate
