Types

type Metadata

type Metadata map[string][]interface{}

Metadata is made as a standalone package to avoid import cycle: influxd -> flux -> flux/interpreter -> flux/execute -> flux

func (Metadata) Add

func (md Metadata) Add(key string, value interface{})

func (Metadata) AddAll

func (md Metadata) AddAll(other Metadata)

func (Metadata) Del

func (md Metadata) Del(key string)

func (Metadata) Get

func (md Metadata) Get(key string) (interface{}, error)

func (Metadata) GetAll

func (md Metadata) GetAll(key string) []interface{}

func (Metadata) Range

func (md Metadata) Range(fn func(key string, value interface{}) bool)

Range will iterate over the Metadata. It will invoke the function for each key/value pair. If there are multiple values for a single key, then this will be called with the same key once for each value.

type SyncMetadata

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

SyncMetadata is a version of `Metadata` which allows concurrent modifications to it

func NewSyncMetadata

func NewSyncMetadata() SyncMetadata

func NewSyncMetadataWith

func NewSyncMetadataWith(meta Metadata) SyncMetadata

func (SyncMetadata) Add

func (md SyncMetadata) Add(key string, value interface{})

func (SyncMetadata) AddAll

func (md SyncMetadata) AddAll(other Metadata)

func (SyncMetadata) Del

func (md SyncMetadata) Del(key string)

func (SyncMetadata) Get

func (md SyncMetadata) Get(key string) (interface{}, error)

func (SyncMetadata) GetAll

func (md SyncMetadata) GetAll(key string) []interface{}

func (SyncMetadata) Range

func (md SyncMetadata) Range(fn func(key string, value interface{}) bool)

Range will iterate over the SyncMetadata. It will invoke the function for each key/value pair. If there are multiple values for a single key, then this will be called with the same key once for each value.

func (SyncMetadata) ReadView

func (md SyncMetadata) ReadView(fn func(meta Metadata))

Provides read access to the underlying `Metadata` map. Since the map may be concurrently modified outside of the closure it should not be allowed to escape it
