Types

type Count

type Count struct {
	uda.AggInterface

	Sum int64
}

func NewCount

func NewCount() (ca *Count)

CONCRETE - these may be suitable methods for general usage

func (*Count) Accum

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

Accum() sends new data to the aggregate

func (*Count) GetInitArgs

func (ca *Count) GetInitArgs() []io.DataShape

func (*Count) GetOptionalArgs

func (ca *Count) GetOptionalArgs() []io.DataShape

func (*Count) GetRequiredArgs

func (ca *Count) GetRequiredArgs() []io.DataShape

func (*Count) Init

func (ca *Count) Init(argMap *functions.ArgumentMap, itf ...interface{}) error

func (Count) New

func (c Count) New() (out uda.AggInterface)

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

func (*Count) Output

func (ca *Count) Output() *io.ColumnSeries

Output() returns the currently valid output of this aggregate
