Types

type DefinitionID

type DefinitionID struct {
	Namespace string
	Name      string
	Version   string
}

DefinitionID represents an ID of a given definition entity. Compliant with the Ditto specification it consists of a namespace, name and a version in the form of 'namespace:name:version'. The DefinitionID is used to declare a Thing's model also it is used in declare the different models a Feature represents via its properties.

func NewDefinitionID

func NewDefinitionID(namespace string, name string, version string) *DefinitionID

NewDefinitionID creates a new DefinitionID instance with the namespace, name and version provided. Returns nil if the provided string doesn't match the form.

func NewDefinitionIDFrom

func NewDefinitionIDFrom(full string) *DefinitionID

NewDefinitionIDFrom creates a new DefinitionID instance from a provided string in the form of 'namespace:name:version'. Returns nil if the provided string doesn't match the form.

func (*DefinitionID) MarshalJSON

func (definitionId *DefinitionID) MarshalJSON() ([]byte, error)

String provides the string representation of a DefinitionID in the Ditto's specified form of 'namespace:name:version'.

func (*DefinitionID) UnmarshalJSON

func (definitionId *DefinitionID) UnmarshalJSON(data []byte) error

UnmarshalJSON marshals definition ID.

func (*DefinitionID) WithName

func (definitionId *DefinitionID) WithName(name string) *DefinitionID

WithName sets the provided name to the current DefinitionID instance.

func (*DefinitionID) WithNamespace

WithNamespace sets the provided namespace to the current DefinitionID instance.

func (*DefinitionID) WithVersion

func (definitionId *DefinitionID) WithVersion(version string) *DefinitionID

WithVersion sets the provided version to the current DefinitionID instance.

type Feature

type Feature struct {
	Definition        []*DefinitionID        `json:"definition,omitempty"`
	Properties        map[string]interface{} `json:"properties,omitempty"`
	DesiredProperties map[string]interface{} `json:"desiredProperties,omitempty"`
}

Feature represents the Feature entity defined by the Ditto's Things specification. It is used to manage all data and functionality of a Thing that can be clustered in an outlined technical context.

func (*Feature) WithDefinition

func (feature *Feature) WithDefinition(definition ...*DefinitionID) *Feature

WithDefinition sets the definition of the current Feature instance to the provided set of DefinitionIDs.

func (*Feature) WithDefinitionFrom

func (feature *Feature) WithDefinitionFrom(definition ...string) *Feature

WithDefinitionFrom is an auxiliary method to set the Feature's definition from an array of strings converted into the proper DefinitionID instances.

func (*Feature) WithDesiredProperties

func (feature *Feature) WithDesiredProperties(properties map[string]interface{}) *Feature

WithDesiredProperties sets all desired properties of the current Feature instance.

func (*Feature) WithDesiredProperty

func (feature *Feature) WithDesiredProperty(id string, value interface{}) *Feature

WithDesiredProperty sets/adds a desired property to the current Feature instance.

func (*Feature) WithProperties

func (feature *Feature) WithProperties(properties map[string]interface{}) *Feature

WithProperties sets all properties of the current Feature instance.

func (*Feature) WithProperty

func (feature *Feature) WithProperty(id string, value interface{}) *Feature

WithProperty sets/adds a property to the current Feature instance.

type NamespacedID

type NamespacedID struct {
	Namespace string
	Name      string
}

NamespacedID represents the namespaced entity ID defined by the Ditto specification. It is a unique identifier representing a Thing compliant with the Ditto requirements: - namespace and name separated by a : (colon) - have a maximum length of 256 characters.

func NewNamespacedID

func NewNamespacedID(namespace string, name string) *NamespacedID

NewNamespacedID creates a new NamespacedID instance using the provided namespace and name. Returns nil if the provided string doesn't match the form.

func NewNamespacedIDFrom

func NewNamespacedIDFrom(full string) *NamespacedID

NewNamespacedIDFrom creates a new NamespacedID instance using the provided string in the valid form of 'namespace:name'. Returns nil if the provided string doesn't match the form.

func (*NamespacedID) MarshalJSON

func (nsID *NamespacedID) MarshalJSON() ([]byte, error)

MarshalJSON marshals namespace ID.

func (*NamespacedID) String

func (nsID *NamespacedID) String() string

String provides the string representation of the NamespacedID entity in the form of 'namespace:name'.

func (*NamespacedID) UnmarshalJSON

func (nsID *NamespacedID) UnmarshalJSON(data []byte) error

UnmarshalJSON unmarshals namespace ID.

func (*NamespacedID) WithName

func (nsID *NamespacedID) WithName(name string) *NamespacedID

WithName sets the provided name to the current NamespacedID instance.

func (*NamespacedID) WithNamespace

func (nsID *NamespacedID) WithNamespace(namespace string) *NamespacedID

WithNamespace sets the provided namespace to the current NamespacedID instance.

type Thing

type Thing struct {
	ID           *NamespacedID          `json:"thingId"`
	PolicyID     *NamespacedID          `json:"policyId,omitempty"`
	DefinitionID *DefinitionID          `json:"definition,omitempty"`
	Attributes   map[string]interface{} `json:"attributes,omitempty"`
	Features     map[string]*Feature    `json:"features,omitempty"`
	Revision     int64                  `json:"-"`
	Timestamp    string                 `json:"-"`
