Functions

func NewScalarOp

func NewScalarOp(val float64) parser.Params

NewScalarOp creates a new scalar op

Types

type FetchNode

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

FetchNode is the execution node TODO: Make FetchNode private

func (*FetchNode) Execute

func (n *FetchNode) Execute(ctx context.Context) error

Execute runs the fetch node operation

type FetchOp

type FetchOp struct {
	Name     string
	Range    time.Duration
	Offset   time.Duration
	Matchers models.Matchers
}

FetchOp stores required properties for fetch TODO: Make FetchOp private

func (FetchOp) Bounds

func (o FetchOp) Bounds() transform.BoundSpec

Bounds returns the bounds for the spec

func (FetchOp) Node

func (o FetchOp) Node(controller *transform.Controller, storage storage.Storage, options transform.Options) parser.Source

Node creates an execution node

func (FetchOp) OpType

func (o FetchOp) OpType() string

OpType for the operator

func (FetchOp) String

func (o FetchOp) String() string

String representation
