Types

type Batch 

type Batch struct {
	Name   string       `json:"name,omitempty"`

	Tags   Tags         `json:"tags,omitempty"`
	Points []BatchPoint `json:"points,omitempty"`
}

func ResultToBatches 

func ResultToBatches(res influxdb.Result, groupByName bool) ([]Batch, error)

func (Batch) Copy added in v0.11.0 

func (b Batch) Copy() PointInterface

func (*Batch) Interface added in v1.0.0 

func (b *Batch) Interface() PointInterface

func (Batch) PointDimensions 

func (b Batch) PointDimensions() Dimensions

func (Batch) PointFields 

func (b Batch) PointFields() Fields

func (Batch) PointGroup 

func (b Batch) PointGroup() GroupID

func (Batch) PointName 

func (b Batch) PointName() string

func (Batch) PointTags 

func (b Batch) PointTags() Tags

func (Batch) PointTime 

func (b Batch) PointTime() time.Time

func (*Batch) SetNewDimTag added in v0.11.0 

func (b *Batch) SetNewDimTag(key string, value string)

func (Batch) Setter added in v0.11.0 

func (b Batch) Setter() PointSetter

func (Batch) ShallowCopyPoints added in v1.3.0 

func (b Batch) ShallowCopyPoints() []BatchPoint

ShallowCopyPoints creates a new slice for the points but only shallow copies the points themselves. Then if a single point needs to be modified it must first be copied.

func (*Batch) UpdateGroup added in v0.11.0 

func (b *Batch) UpdateGroup()

type BatchPoint 

type BatchPoint struct {
	Time   time.Time `json:"time"`
	Fields Fields    `json:"fields"`
	Tags   Tags      `json:"tags"`
}

A point in batch, similar to Point but most information is found on the containing Batch.

Tags on a BatchPoint are a superset of the tags on the Batch All points in a batch should have the same tag and field keys.

func BatchPointFromPoint 

func BatchPointFromPoint(p Point) BatchPoint

type Dimensions added in v0.11.0 

type Dimensions struct {
	ByName   bool
	TagNames []string
}

func (Dimensions) Copy added in v0.11.0 

func (d Dimensions) Copy() Dimensions

func (Dimensions) ToSet added in v1.0.0 

func (d Dimensions) ToSet() map[string]bool

type Fields 

type Fields map[string]interface{}

func (Fields) Copy 

func (f Fields) Copy() Fields

type GroupID 

type GroupID string
const (
	NilGroup GroupID = ""
)

func ToGroupID added in v1.0.0 

func ToGroupID(name string, tags map[string]string, dims Dimensions) GroupID

type Point 

type Point struct {
	Name            string
	Database        string
	RetentionPolicy string

	Group      GroupID
	Dimensions Dimensions

	Tags Tags

	Fields Fields

	Time time.Time
}

Represents a single data point

func (Point) Bytes

func (Point) PointGroup 

func (p Point) PointGroup() GroupID

func (Point) PointName 

func (p Point) PointName() string

func (Point) PointTags 

func (p Point) PointTags() Tags

func (Point) PointTime 

func (p Point) PointTime() time.Time

func (*Point) SetNewDimTag added in v0.11.0

	PointFields() Fields

	// Return a copy of self
	Copy() PointInterface
	Setter() PointSetter
}

Common interface for both Point and Batch objects

type PointSetter interface {
	PointInterface
	SetNewDimTag(key string, value string)
	UpdateGroup()
	Interface() PointInterface
}
