Functions ¶
func FeatureKey ¶
FeatureKey represents a feature database key.
func FeaturesKeyPrefix ¶
FeaturesKeyPrefix represents all thing's features database key prefix.
func SystemThingKey ¶
SystemThingKey returns the SystemThingData key.
Types ¶
type FeatureData ¶
type FeatureData struct {
// ID represents the Feature ID.
ID string
// ThingID matches the feature's thing ID, i.e. the ThingData.ID value.
ThingID string
// Definition represents model.Feature definitions string representations.
Definition []string
// Properties represents model.Feature properties.
Properties map[string]interface{}
// Properties represents model.Feature desired properties.
DesiredProperties map[string]interface{}
}
FeatureData represents the persistable model.Feature structure.
func (*FeatureData) Data ¶
func (data *FeatureData) Data() interface{}
Data returns the persistable data.
func (*FeatureData) Value ¶
func (data *FeatureData) Value(value interface{})
Value returns the created instance from the stored data.
type StoreData ¶
type StoreData interface {
// Key returns the storage key.
Key() string
// Data returns the persistable data.
Data() interface{}
// Value returns the created instance from the stored data.
Value(interface{})
}
StoreData provides key-value persitable pair
type SystemThingData ¶
type SystemThingData struct {
// ThingID matches the model.Thing namespace ID string representation.
ID string
// Revision represents the thing local revision that is initialised with the added model.Thing
// revision and increased on each thing's data modification, including its features modifications.
Revision int64
// Timestamp represents the thing local timestamp that is the timestamp of each
// thing's data modification, including its features modifications.
Timestamp string
// DeletedFeatures is a system field that contains the feature IDs of locally deleted features only,
// i.e. not synchronized with the remote feature existence state.
DeletedFeatures map[string]interface{}
// UnsynchronizedFeatures is a system field that contains the feature IDs of locally modified features only,
// i.e. not synchronized with the remote feature state.
// For each unsynchronized feature the revision for its offline change is stored.
UnsynchronizedFeatures map[string]int64
}
SystemThingData is used for Things Storage system data representation.
func (*SystemThingData) Data ¶
func (data *SystemThingData) Data() interface{}
Data returns the persistable data.
func (*SystemThingData) Key ¶
func (data *SystemThingData) Key() string
Key returns the datatabase key.
func (*SystemThingData) Value ¶
func (data *SystemThingData) Value(value interface{})
Value returns the created instance from the stored data.
type ThingData ¶
type ThingData struct {
// ThingID matches the model.Thing namespace ID string representation.
ID string
// PolicyID matches the model.Thing policy ID string representation.
PolicyID string
// DefinitionID represents the model.Thing definition string representation.
DefinitionID string
// Attributes represents the model.Thing attributes.
Attributes map[string]interface{}
}
ThingData represents the persistable model.Thing structure.
