Functions

func Get

func Get(path []string, object interface{}) interface{}

Get returns the attribute of the object at path

func GetValue

func GetValue(path []string, object interface{}) (*types.Any, error)

GetValue returns the attribute of the object at path, as serialized blob

func List

func List(path []string, object interface{}) []string

List lists the members at the path

func NewPluginFromChannel

func NewPluginFromChannel(writes <-chan func(map[string]interface{})) metadata.Plugin

NewPluginFromChannel returns a plugin implementation where reads and writes are serialized via channel of functions that have a view to the metadata. Closing the write channel stops the serialized read/writes and falls back to unserialized reads.

func NewPluginFromData

func NewPluginFromData(data map[string]interface{}) metadata.Plugin

NewPluginFromData creates a plugin out of a simple data map. Note the updates to the map is not guarded and synchronized with the reads.

func Path

func Path(path string) metadata.Path

Path returns the path compoments of a / separated path

func PathFromStrings

func PathFromStrings(a string, b ...string) metadata.Path

PathFromStrings returns the path from a list of strings

func Put

func Put(path []string, value interface{}, object map[string]interface{}) bool

Put sets the attribute of an object at path to the given value

func String

func String(p metadata.Path) string

String returns the string representation of path
